      MonDO: MONDO:0032706

      Case: Patient AW, Belgian female developed mild gait imbalance at age 38 years with progressive decline with clear dementia at age 53 years. She died at age 62 years due to infectious complications. Homozygous for GCAP2:c.1198_1199insG; p.(His400fs*15). The variant and its segregation were confirmed in the proband and her daughter using standard Sanger sequencing methodology.

      DiseaseAssertion: Cerebellar ataxia

      FamilyInfo: No consanguineous family. Her brother died from brain tumor, her father had epilepsy and died at 84 years old, her mother was alive without ataxia or gait disorder at age 85 years. Daughter is healthy.

      CaseNOTHPOs: HP:0000639 (Nystagmus)

      CasePreviousTesting: Brain MRI at age 53 years revealed severe atrophy of the cerebellum, both vermian and hemispheric, mainly of the superior aspect, and also global cerebral atrophy (cortical and central). Levels of alpha-fetoprotein, vitamin E, copper, and folic acid were normal. Screening for trinucleotide repeat expansions was negative for SCAs 1, 2, 3, 6, 7, 8, 10, 12, and 17, and for Friedreich’s ataxia. Post-mortem brain examination revealed cerebellar atrophy in combination with a mild atrophy of the pes pontis. Normal nerve conduction studies. Normal opthalmological evaluation.

      GenotypingMethod: Exome sequencing. Sanger sequencing was performed for confirmation of the variants and for segregation analyses using standard techniques. 90 560 single-nucleotide variations and 8961 indels were called. No obvious variants in known ataxia genes were observed. Variants were filtered for variant type, rarirty (MAF <0.5%) and conservation (>0.75, phyloP). Trio-sequencing analysis to detect putativede novo variants was not possible because of the unavailability of paternal DNA for Patient NIJ and parental DNA for Patient AW.

      Functional evidence: Drosophila fly GDAP2 model supports a role of GDAP2 in motor behaviour and suggests that cellular stress might be driving the neurodegenerative cascade. Ubiquitous Gdap2 RNAi-1 knockdown results in droopy wings. Gdap2 knockdown does not result in increased levels of apoptotic cell death in central brain upon 18 hours paraquat exposure.

    1. In family L, the novel variant p.Lys22Asn was predicted to be pathogenic by both CADD and MutationTaster, and its frequency in the population is unknown. This variant may be related to the presentation of Stargardt disease in two individual cases. In individual I1, this variant was associated with the complex allele p.[Ser1642Arg; Val1682_Val1686del], whereas in individual II2, this variant was associated with the p.Gly1901Glu variant. This repetition may support the hypothesis that the variant is indeed pathogenic.

      Family L has this variant segregating through

    1. family A, only 2 of 37 candidate variants segregated with the disease in the family (Table 2 and Table S3). These two mutations were homozygous missense mutations in EXTL3 (c.1537C>T [p.Arg513Cys] [GenBank: NM_001440.3]) and CHST9 (MIM: 610191; c.1133A>G [p.Asn378Ser] [GenBank: NM_031422]) (Figure 2B)

      VariantEvidence:

    3. On the basis of sequence similarity and in-silico modeling, the p.Leu163Val mutation is predicted to lie within the first helix and to be protein destabilizing (DUET7 ΔΔG score: 1.418Kcal/mol). On the basis of amino acid conservation between homeodomains, the leucine residue is predicted to be highly conserved.

      Family 3

      Variant, (NM_177400.2; c.487C>G; p.Leu163Val), replaces conserved leucine within the first helix of the homeodomain, therefore destabilizing the protein.

      SupplementalData: n/a

    1. Our Rab39b KO mice displayed similar autism-like behaviors to those seen in the mutant mouse model of Chd8 (Platt et al. 2017), mutations of which are strongly associated with ASD. Despite its enrichment in neurons, Rab39b appears to be ubiquitously expressed in the different regions of the brain.

      NonHumanModel: Zhang_Mouse

      GeneAlteration: Exon 2 of RAB39B was targeted using two gRNAs and Cas9 mRNA in the C57BL/6N background. Mice harboring 397-bp deletions in exon 2 were obtained.

      ModelPhenotype: HP:0000256 Social and memory deficits

      HumanPhenotype: HP:0001249, HP:0000256

      ModelEvidence: Similar to PMID: 33364235, authors show through ASD-related tests that KO mice exhibit social and memory deficits. They also show that RAB39B variation results in over-proliferation and differentiation deficits of neural progenitor cells, which results in larger that normal number of neurons. Mice therefore have macrocephaly.

      ModelVariant:

      WhereInPaper:

      The model is scored reduced points as the mice recapitulate the ASD phenotype seen in some human patients with RAB39B variants, but does not provide evidence for the Parkinson disease phenotype. (0.5)

    1. Undifferentiated N2A cells were infected with two independent shRNAs against Rab39b

      NonPatientCell: EFO:0005214

      GOterm: GO:0016192

      GeneAlteration: Undifferentiated N2A cells (murine neuroblastoma cell line) were infected with shRNAs to downregulate endogenous Rab39b expression by 45%.

      FunctionalEvidence: N2A cells 4d after treatment with shRNA showed a change in morphology. Clumps of actin and reduced and/or altered membrane protrusions were observed. Rescue with WT RAB39B was able to restore the normal actin and cytoskeletal morphology, indicating that Rab39b may alter intracellular vesicular trafficking steps essential for membrane remodeling.

      NonPatientCell: CL:0002608

      GOterm: GO:0016192

      GeneAlteration: Rab39b expression was knocked down in mouse primary hippocampal neurons using shRNA

      FunctionalEvidence: Expression of Rab39b was reduced by 40% as determined by RT-PCR. Morphological analysis showed significant alteration and the number of growth cones was decreased at each neurite terminal. Authors also show that RAB39B was localized to growth cones and could be involved in intracellular trafficking related to membrane recycling of Golgi-derived vesicles. Therefore RAB39B gene alterations can lead to impaired trafficking and lead to accumulation in membrane content and disorganized growth of growth cones.

    1. RESULTS

      NonHumanModel: Mouse (Mus musculus)

      GeneAlteration: Two approaches were used to create this model. The first imitated the slow fiber-specific expression of TPM3 by linking the coding region for αTm_slow(Met9Arg) to a human troponin I slow gene that drives expression specifically in these fibers via EcoRI-PstI digest and ligation into a linearized construct. The second, HSA–αTm_slow(Met9Arg), expressed the mutation in fast fibers by ligating a SmaI-BamHI cassette containing the intron and 3′-UTR of SV40 small t antigen directly downstream of the mutant cDNA sequence followed by blunt-end ligation of the HSA promoter into the EcoRV site upstream of the sequence before linearizing into a construct. These constructs were injected into fertilized eggs and screened by southern blot analysis to verify the successful insertion.

      HumanPhenotype: HP:0003798, HP:0003557, HP:0001324, HP:0011807 (Nemaline bodies, Increased variability in muscle fiber diameter, Muscle weakness, Type 1 muscle fiber atrophy)

      HumanFreeText: Disorganized sarcomeres

      ModelEvidence: The Met9Arg mouse models not only clearly recapitulate the phenotypes of nemaline/other myopathies but also provide evidence to suggest possible pathogenic mechanisms of the mutated allele in vivo. Mice expressing the mutated allele display nemaline rods and clear fiber-type disproportion, both of which are hallmarks for their respective diseases. They also displayed progressive muscle weakness starting around 5-6 months of age, a phenotype that matches the childhood-onset muscle weakness and other progressive symptoms common in TPM3-related congenital myopathy patients. Another classic phenotype, atrophy of Type I muscle fibers with a corresponding hypotrophy of Type II fibers was also present in the mice. This may be related to the increased number of slow/fast oxidative fibers in the mutant mice leading to the disruption of normal muscle fiber maturation. The mice also displayed some cytoplasmic bodies and tubular aggregates; these have been observed in varying functional studies and similar features have also been observed in humans.

      FamilyAddInfo: Patient 1 born full term with no complications, disease symptoms presented at 2mo of age with nystagmus. Gastrostomy at 2 years. Required chemodenervation for dystonia. Had transitory respiratory failure or apnoeic episode at 2 years. MRI showed increased signal in anterior nucleus of thalamus, and atrophy of cerebellar vermis.

    1. Patient 1 She was born at term to first cousin parents of Pakistani origin. She presented to the dermatologist at the age of 9 months with hyperpigmentation and hypertrichosis, particularly on her back and legs (Fig. 1A). Physical examination showed extensive hyperpigmented areas with dark, long hairs over the buttocks, legs and arms. In addition, she showed limited dysmorphism: epicanthal folds, hypertelorism, widely spaced nipples and lipoatrophy of buttocks. A skin biopsy from the hyperpigmented area of her legs showed non-specific inflammation. Figure 1Open in figure viewerPowerPoint (A) Marked hypertrichosis on the lower legs. (B) Hypermelanosis on the inner aspects of the thighs. (C) Close up of (B) showing the marked hypermelanosis and hypertrichosis. In the subsequent 2 yr, failure to thrive became clear and she suffered from recurrent pyrexia’s and chronic diarrhoea. She was noted to have hepatosplenomegaly, lymphadenopathy, anaemia and mild ascites with peripheral oedema. Numerous investigations failed to explain the underlying cause. At 4 yr of age, because of the polyuria and polydipsia, she was diagnosed with diabetes mellitus necessitating insulin treatment. Islet cell and glutamic acid decarboxylase antibodies were negative. As a result of the persistent diarrhoea, faecal stool elastase was measured, which was found to be undetectable, and pancreatic enzyme replacement therapy was started. Diarrhoea persisted however, and growth slowed down [at 4.4 yr height was at −2.9 standard deviation score (SDS), at 7.6 yr height was at −3.99 SDS]. She showed hirsutism with sparing of her knees and elbows. The skin on her arms and legs showed increased tightening over the years, and similarly her face became affected. The lymphadenopathy spread and was present in the groins and axillae. Biopsies from both lymph nodes and subcutaneous tissue showed fibrofatty connective tissue with fibrosis and mononuclear cell infiltrates around the larger vessels. Inflammatory markers such as erythrocyte sedimentation rate (ESR) (160 mm/hr), and C-reactive protein (CRP) (62 mg/l) were constantly raised. Her liver and spleen were enlarged. At 7 yr, she developed increasing shortness of breath and lethargy. An echocardiogram showed mild left ventricular dilatation. A trial of oral prednisolone therapy caused some reduction in her ESR level (65 mm/hr), improved her clinical condition and activity levels and reduced lymphadenopathy. When steroid were weaned, her ESR again increased to 99 mm/hr. At the most recent physical examination at the age of 7.9 yr, her height was 101.7 cm (−4 SDS) and weight was 18.5 kg (−2.26 SDS). Her diarrhoea had settled on pancreatic enzyme replacement therapy. On prednisolone therapy, she was more energetic and less breathless. Her dermatosis had remained unchanged and she continued to have hepatomegaly (liver palpable 10 cm below the right costal margin) and splenomegaly (spleen palpable 2 cm below the left costal margin). Otherwise physical examination (including neuromuscular examination) gave normal results. She had a normal cognition. Ophthalmologic examination showed myopia with astigmatism but no signs of retinopathy. Audiometry showed a conductive hearing loss of 30 dB for which bilateral grommets were inserted. Her brain and spinal cord magnetic resonance imaging was normal, skeletal survey showed only mild sclerosis of the skull vault but otherwise gave normal results. Her karyotype was normal female, 46,XX. Immunological investigations revealed isolated immunoglobulin (Ig)A deficiency, raised IgG1, IgG2, and IgG3 with persistently raised ESR and CRP. Antibody screens for autoimmune disease were negative. She had an oral glucose tolerance test that showed elevated blood glucose with undetectable insulin concentration.

    1. Since 2000 we have performed 54 HSCT procedures (on 44 children) for MPSIH at Manchester (Table 1). Of these, six (13.6 %) displayed significant cardiomyopathy at presentation. Interestingly three of these were from the same extended pedigree (from Kuwait), sharing the R628X IDUA gene mutation. All children were diagnosed within the first 4 months of life with dilated cardiomyopathy and significant LV functional impairment. Symptomatic cardiac failure was the predominant presenting feature in five children, with silent cardiomyopathy identified on screening echocardiography in the other. Median FS and EF at diagnosis were 12.5 % (range 3–20 %) and 35 % (15–40 %) respectively. Electrocardiography (ECG) patterns varied, but included strikingly tall QRS complexes consistent with LV enlargement/hypertrophy and evidence of myocardial ischaemia (ST segment depression; T wave inversion) in several cases. Further detailed cardiac investigation (including serum troponin) was rarely performed.

      Case#: Patients 2 (male), 4 (male), and 5 (female). Kuwait. Onset between 1wk-3mo.

      DiseaseAssertion: MPS I Hurler

      FamilyInfo: Patients are from the same extended pedigree (family in Kuwait)

      CasePresentingHPOs: α-L-iduronidase activity= 3.73 umol/g/hr (normal range 10–50) after commencing ERT. ERT for 9 wks. Congestive cardiac failure. LV fractional shortening=10%. LV ejection fraction=29%. HSCT at 17mo. α-L-iduronidase activity= 11.24 umol/g/hr (normal range 10–50) at follow up. GAG= 31.3 after transplant. Enzyme replacement therapy results in a significant reduction in urine GAGs (either total or heparan sulfate)

    1. Other MPS I-H nonsense mutations (W180X, Y343X, Q400X and R628X), harbored in the compound heterozygous state, were also challenged, resulting in relevant rescue upon treatment with the exception of the Y343X variant. The highest degree of functional rescue was observed for the R628X/W402X heterozygote, suggesting additive effects of the R628X mutation, whose sequence context (UGAC) is predicted to be highly susceptible to suppression over the unresponsive W402X [57].

      This paper evaluated factors shaping the outcome of readthrough, namely the nucleotide and protein context, with the latter being pivotal to produce functional full-length proteins. This variant was mentioned as a MPS I-H nonsense mutation, but no new case or experimental information.

    1. A total of 801 stroke patients were enrolled in the study (Figure 1). We excluded 91 patients who did not have muscle symptoms with CK elevation or had tolerable myalgia without CK elevation. Seven patients were excluded because their baseline CK levels were not less than 480 U/L. Eleven patients were excluded because their CK levels were elevated by other medical issues including myocardial infarction and surgical procedures. We also excluded four patients as their DNA samples were insufficient for analysis. As a result, 688 patients were included in the analysis. Of the included patients, 56 experienced statin-associated muscle symptoms. Twelve patients underwent myopathy (SRM 3) after statin treatment, and two patients experienced severe myopathy (SRM 4). Forty-two patients had intolerable myalgia (SRM 2). The remaining 632 patients who never experienced SRM were classified as the control group.

      Korean stroke patients who were carriers of COQ5 rs10849757 were more associated with statin related myotoxicity risk than wild-type homozygote carriers (GG) (9.7% vs. 3.9%, p = 0.024). Only group demographics provided rather than individual phenotype/genotype information

      PreviouslyPublished: PMID: 18410979

      VariantEvidence: Kang et al. (2010; PMID: 20595384) performed functional characterization of the G437R mutation in Xenopus oocytes and observed transport activity that was approximately half that of wildtype SLC29A3. Studies in NIH 3T3 fibroblasts demonstrated accelerated turnover of the G437R mutant compared to wildtype, suggesting decreased stability.

      VariantEvidence Immunofluorescence of SLC26A1 protein, when overexpressed in HEK293 cells, showed that p.Thr185Met causes protein to fail to reach plasma membrane (Figure 2). Monitoring of intracellular pH showed that p.Thr185Met has severely reduced activity (Figure 4). PCR of slc26a1 transcript in H293K cells showed no change in amount of transcript suggesting that the low p.Ser363Leu band levels in the immunoblot (Figure 3) were due to low portein stability.

    2. In a European-American boy (B641-12) who had nephrolithiasis and was born to consanguineous parents, we detected a homozygous missense mutation in SLC26A1 (Table 1, Figure 1, and Figure S1). The paternal grandfather of this individual also had nephrolithiasis. A kidney stone was initially found in this individual during a computerized tomography scan, which was performed for the evaluation of abdominal pain. In a 24 hr urine test, oxalate was within normal range (Table S2). Renal function of this individual was normal. The detected missense mutation (c.166G>A, p.Ala56Thr)

    1. To assess the characteristics and distribution of causal variants for Mendelian disorders in the ChinaMAP, we filtered the pathogenic variants with the annotation of ClinVar database (20180603)22,23 and HGMD (Human Gene Mutation Database, 2016.2),24 and further analyzed the disease-causing variants following the guidelines from the ACMG (American College of Medical Genetics and Genomics).25 A total of 2026 variants or 1619 variants in the HGMD DM set were annotated as pathogenic or likely pathogenic by the ClinVar or ACMG, respectively (Fig. 3c and Supplementary information, Table S7).

      Database information for this variant was compiled on supplementary table s7, but no new case or experimental data.

    1. While our current study confirmed phenotypic effect of Rab39b KO on motor skill learning and social memory, more importantly, we further investigated the detailed role of RAB39B in learning and memory. We found that Rab39b KO mice exhibited defects in short-term working memory, novel objection recognition memory, and spatial memory. Moreover, Rab39b KO mice exhibited impaired synaptic plasticity and altered synaptic structure and PSD composition.

      NonHumanModel: Niu_Mouse

      GeneAlteration: Transcription activator like effector nuclease (TALEN) - mediated strategy was used to target exon 1 of RAB39B to generate the knockout mice in the C57BL/6J background. A mouse line with a "GT" deletion at nucleotide 106-107 that caused a frameshift and early truncation of RAB39B was obtained. Authors confirmed absence of RAB39B loss of fucntion.

      ModelPhenotype: Learning and memory deficits

      HumanPhenotype: HP:0001249

      ModelEvidence: 2-mo hemizygous male knock-out (KO) mice showed behavioral alterations compared to WT mice. KO mice showed reduced anxiety, impaired recognition memory, impaired short-term working memory, impaired spatial memory, impaired social novelty recognition, compromised motor skill learning, but motor ability was not affected. Authors indicate that impaired learning and memory was associated with altered synaptic plasticity.

      RescueMethod Fibroblasts transfected with lentiviral vector containing single copy of WT TRMT10C.

      RescueEvidence Transfected patient cells had increased MRPP1 expression, restored mitochondrial translation, normalized levels of respiratory chain complexes and mt-tRNA precursors which rescues the reduced cellular oxidative phosphorylation and slowed growth. 21857155 demonstrates both the restriction of translation and reduction of the rate of oxidative phosphorylation during MRPP1 knockdown in HeLa cells (Fig 5). Those result corroborate the gap between reduced MRPP1 expression and reduction in translation of oxidative phosphorylation machinery.

    1. Gene and mutation identification Analysis of the single nucleotide polymorphism (SNP) microarray genotypes from six patients with PHID identified a single common 1.4 Mb region of shared homozygosity within cytogenetic band 10q22.1, between SNPs rs10509321 and rs1900515 (Fig. 1A). Inspection of the Ensembl and UCSC Genome Browsers demonstrated that the region included 14 known and predicted genes: ADAMTS14, C10orf27, CDH23, EIF4EBP2, LRRC2, KIAA1274, NODAL, NPFFR1, PCBD1, PPA1, PRF1, SLC29A3, SGPL1, UNC5B. Positional candidate genes were selected for sequencing in order to identify pathogenic mutations (Fig. 1B). Five different homozygous mutations were identified in the SLC29A3 gene encoding the equilibrative nucleoside transporter 3 (Fig. 1C, Table 1). Human ENT3 has been shown recently to be the cause of H syndrome, an autosomal recessive disorder with overlapping skin features to PHID (6), indicating that these are allelic disorders. hENT3 belongs to a structurally unique protein family of nucleoside and/or nucleobase transporters (13,14). The five homozygous mutations identified segregated with the disease within each family and were not present in over 100 Lebanese and Pakistani control chromosomes.

The deletion causes a frame shift mutation p.Y314Tfs in transmembrane domain 7 and is predicted to result in the substitution of transmembrane domains 8–11 with an irrelevant protein sequence of 91 amino acids derived from an alternate reading frame. The nonsense mutation p.E444X is predicted to lead to premature protein truncation with loss of part of the final cytoplasmic domain and transmembrane domain 11 of hENT3. It would appear unlikely that the either residual protein would be capable of nucleoside transport function.Three homozygous missense mutations of SLC29A3 were identified to involve conserved amino acids (Table 1). The first missense mutation involves Methionine116 in transmembrane domain 2, which is a hydrophobic amino acid in species as distantly related as humans and nematodes, with a large basic amino acid, Arginine (p.M116R; Fig. 1C and E). The Grantham score for this substitution is 91, which is classified as a moderate change (15). Analysis using the SIFT prediction software also classifies this as a likely deleterious change (16). The introduction of a large basic amino acid into a transmembrane domain would likely result in significant disruption of the hydrophobic nature of the domain and result in retention of the transporter protein within the endoplasmic reticulum, as has been demonstrated for other membrane proteins (17).The second missense change is a recently reported Glycine to Arginine substitution at hENT3 amino acid 437 (p.G437R Fig. 1C), which is located in the putative cytoplasmic domain between transmembrane domains 10 and 11. This is the only mutation in the PHID cohort that is shared with the known mutations in H syndrome. Of particular interest is the observation that this is the sole individual in the PHID cohort who has not developed insulin-dependent DM. The p.G437R change involves the substitution of a large basic amino acid at a position where 41 members of the ENT family as distantly related as humans and Arabidopsis thaliana encode a small hydrophobic amino acid (Fig. 1E) (18). The Grantham difference for this change is 125 and is classified as a moderately radical change.The third missense change occurs at hENT3 amino acid residue 449, which is also located in the final putative intracellular domain between transmembrane domains 10 and 11, and involves the substitution of a Threonine by an Arginine (p.T449R). The amino acids encoded at this position in hENT3 orthologs are small polar/uncharged or small hydrophobic residues (Fig. 1E). Substitution by arginine is associated with a Grantham score of 71 and is predicted by SIFT as not to be tolerated.

      SupplementalData:

    1. The older brother, P1 (Figure 1A, B), is the first child of first-cousin parents of Moroccan origin. He was born at term, with normal health indicators and metrics, following an uneventful pregnancy. P1 has an adult height of 162 cm, which is close to 167 cm, his predicted adult height based on the heights of his parents (his father is 168 cm tall and his mother is 155 cm tall). He was diagnosed with insulin-dependent diabetes at the age of 5 years. He was subsequently diagnosed with exocrine pancreas insufficiency at the age of 9 years, following the observation of bulky stools and steatorrhea with levels of fat in stool at 12 g/24 hr. At this stage, a diagnosis of cystic fibrosis was excluded and a computed tomography (CT) scan of the pancreas was normal. At the age of 14 years, nasal obstruction occurred, with infiltrates found in both the nose and the right maxillary sinus (Figure 1C). P1 was then diagnosed with RS. Several operations were required to free the nasal fossae, between the ages of 14 and 18 years. An improvement was observed after the initiation of antibiotic treatment, but multiple relapses occurred 10 months after treatment, despite the use of various combinations of antibiotics. Apparently spontaneous recovery was observed from the age of 18 years onwards. Biological signs of inflammation persisted, with both a high erythrocyte sedimentation rate (>50 mm) and polyclonal hypergammaglobulinemia (IgG = 15.3 g/l, IgA = 4.2 g/l, IgM = 2.8 g/l). Finally, P1 developed a very mild contracture of the fingers and toes at the age of 12 years (Figure 1D). At last follow up, the patient was 33 years old and had insulin-dependent diabetes and exocrine pancreatic deficiency. He is doing well, with daily subcutaneous insulin and oral pancreatic extract treatments, which have normalized his glycemia and steatorrhea. He has required no further surgery since the age of 18 years, but still suffers from chronic nasal obstruction and an enlarged nose due to the presence of a nasal mass (Figure 1B). He recently suffered from local pain of the knee. X-ray revealed lytic bone lesions of both patellas (Figure 1E). No other lesions were detected on X-ray or bone scintigraphy. This patient is otherwise healthy (Table 1). Both cardiac morphology and function were normal on cardiac ultrasonography (US). Dermatologist examination revealed no pigmented hypertrichotic skin lesions and skin biopsies taken at 3 different sites were normal. Speech and tone audiometries were normal. Ophtalmologic examination revealed mild diabetic retinopathy but no uveitis and no histiocytic infiltration.

      CasePreviousTesting:

      CaseGenotypingMethod: genome-wide linkage (GWL) analysis by homozygosity mapping and whole-exome sequencing (WES) by next-generation deep sequencing. Sanger sequencing for validation.

      Variant: c.243delA (p.Lys81fs) homozygous

      ClinVarID: or CAID: 636986 / CA913184824

      gnomAD: This frameshift variant, Lys81fs which is occurs in exon 2, is absent from gnomAD. Down-scoring for consanguinity and alternative splicing.

      AddCaseInfo: First-cousin, heterozygous parents. Proband has 1 affected sister who is also a homozygote. Proband also has a variant in VCL (c.610G>C) which is predicted benign and associated with HCM, which the proband does not have.

      PreviouslyPublished: PMID: 18947330

      VariantEvidence: This mutation decreases the levels of transcript variant 1 through NMD and results in an absence of the WT protein, but allows the expression of a mutated mRNA transcript variant 3, which would ordinarily be subject to NMD. This hENT3-variant3-81fs variant was expressed but displayed lower levels of adenosine transporter activity than the hENT3-variant1-WT protein.

    1. RT-PCR analysis of mRNA samples from five unrelated patients with mutations affecting the 3′ end of exon 3 (c.550G>C, c.550G>A, and c. 550+5 G>A) performed by our group, showed an additional transcript lacking exon 3. Second, the semi-quantitative comparison of the expression of both variants in controls and patients on agarose gels, revealed an apparently higher expression of the exon 3 skipped variant in these patients than in controls

      FunctionalEffect: RT-PCR of mRNA samples from patients blood showed an additional transcript lacking exon 3. Expression in agarose gels revealed a higher expression of the exon 3 skipped variant in these pts vs controls.

    2. 2 Clinical presentationThe patient was a 4 yr-old boy referred to Myelin Disorders Clinic at Children's Medical Center, Tehran, Iran in 2017 due to macrocephaly and abnormal facies. He was the second child born to a consanguineous marriage. He was born after a full-term, uneventful pregnancy with a birth weight, length and head circumference (HC) of 4200 g, 47 cm and 39 cm, respectively. Within the first months of life, macrocephaly and puffy eyelids were noted, but motor, cognitive and speech developmental milestones were compatible with chronological age at age one yr-old. HC at age of 1 year was 49 cm (>+2 Z-score). By the age of 2 yr, he developed umbilical hernia, which later underwent surgical operation, but it was not completely disappeared, so that it was visible at the time of our examination at 4 yr old in spite of previous corrective surgery. From age of 3 yr-old up to now, half a tablet per day of levothyroxine has been prescribed for him due to clinical suspicion of hypothyroidism, but review of his medical documents did not reveal abnormal thyroid function tests. By the age of 4 yr, when he referred to Myelin Disorders Clinic, his head circumference and height were 54.5 cm (>+3 Z-score) and 106 cm (>-2 Z-score), respectively ( Fig. 1 .A). Developmental milestones regarding Denver Developmental Screening Test (DDST) were normal. Neurologic examinations were normal but systemic exams showed abnormal facial characteristics including sparse eyebrows, high forehead, broad nasal bridge, epicanthic folds, downward slanted palpebral fissures, long philtrum, retro-micrognathia, full lips, coarsening appearance, gingival hyperplasia and premature teeth. Clinical examination also showed flat feet, hyperextensible skin, joints hyperlaxity and easy bruising. No symptom of ichthyosis or scoliosis were noticed. A large hypopigmented skin lesion under anterior abdominal region around umbilicus was observed ( Fig. 1 .B-E). His parents claimed that the skin lesion was the remaining of an old burn. Open full size image Fig. 1 Diagram of head circumference of index case over time is shown by black dots. Standard deviation (SD) lines with the corresponding Z-score are presented (A). Clinical features of the proband: coarse facies with downward slanted palpebral fissures, high forehead, broad nasal bridge, epicanthic folds, retro-micrognathia, Puffy droopy eyelids, full everted lips and sparse eyebrows (B), gum hypertrophy, irregular dentition long philtrum (C), flat feet (D) and umbilical hernia (E). First brain MRI of patient at age 4 years. Axial and coronal planes at the level of basal ganglia and centrum semiovale, in T2 weighted spin echo and FLAIR sequences images reveals diffuse abnormal white matter signal more pronounced at superficial subcortical and deep peritrigonal regions (F, G, H). Bilateral anterior temporal small subcortical cysts formation (I, J-black arrows) and increased perivascular spaces in posterior deep white matter are noticed clearly visible in FlAIR sequence images (K-black arrow). Sequence chromatogram showing homozygote and heterozygote state of NM_001242581.1: c.2251dup mutation in the parents and affected boy (L).For more detailed evaluations brain MRI and complementary metabolic studies using gas chromatography–mass spectrometry (GC-MS) were performed. Eventually whole exome sequencing (WES) was performed to look for a probable genetic factor involved in leukoencephalopathy and abnormal facies.

    1. Altered p.K7del protein distribution as detected by in vivo modelling in the zebrafish

      NonHumanModel: Zebrafish

      GeneAlteration: TPM2 complementary DNA was obtained and subcloned in-frame with GFP by PCR using the 5' CMV/SP6 promoter. Site-directed mutagenesis was performed to engineer the DNA with the p.K7del mutation. Afterwards, both types of complementary DNA were injected into stage 1 zebrafish embryos. Myofibers were isolated and analyzed from 4- and 7-day post fertilization zebrafish.

      ModelPhenotype: N/A

      ModelFreeText: 3x decrease in TPM2 width, Disorganized sarcomeres, Localization of TPM2 to the z-band, Decreased overall sarcomere length, Accumulations of Actinin

      HumanPhenotype: N/A

      HumanFreeText: Disorganized myofibrils and abnormal Z bands, Disorganized sarcomeres, Nuclear clumps

      ModelEvidence: This in vivo zebrafish model reflects several of the muscular phenotypes that are displayed in many nemaline myopathy patients. Although only the myofibres were studied, which does not allow for gross muscular phenotypes to develop, there are clear similarities. The disorganized/shortened sarcomeres are commonly seen in muscle biopsies in patients, as well as actin-based nuclear clumps that accumulate. The z-bands and myofibrils can also be demonstrated in nemaline myopathy patients, although the patterns observed are somewhat dissimilar.

A fibroblast line from this patient with the infantile form of the disease was investigated for mutations by single strand conformation polymorphism analysis and direct sequencing of PCR products. A nonsense mutation was found which generated a stop codon at codon 284. The study investigated the steady-state level of mRNA produced by cells containing stop codons using a competitive polymerase chain reaction technique and found that at codon 284, the mRNA levels were 0.8%, as percent of normal per single gene dose.

      CasePMIDs:

    1. We identified two unrelated children with DSS. Their clinical features are given in Table 1 and their radiographs are shown in Figure 1. They presented with fractures, cortical thickening and widening of the diaphysis of the long bones, cranial base sclerosis, broad ribs with sclerosis and platyspondyly. Subject 1 suffered from recurrent ear and skin infections between the ages of 8 and 11 months. Subject 2 presented with a pulmonary infection at two years of age and later necessitated surgical removal of her adenoids for breathing difficulties. Bone marrow biopsies were not performed in either child. Neither child had neurological symptoms or dental anomalies. Only subject 1 had skin findings, which were recurrent transient erythematous papules on the lower abdomen (1). Dual-energy X-ray absorptiometry for subject 1 showed a lumbar spine BMD Z-score of +8.1 at 2 years of age, and +11.9 at 5 years of age. Because she has short stature, these greatly elevated bone density scores are actually underestimates (6).

Images from subject 1 at 33 months (and 22 months for the pelvis) are from Whyte et al. (1), and have been reproduced with authorization from the publisher. For subject 2, radiographs were taken at 4 years of age. Note the sclerosis at the skull base, periphery of the iliac wings and metaphyses, platyspondyly, and in the long bones cortical thickening at the diaphysis, diaphyseal enlargement with relative radiolucency and a fracture in subject 2.We performed whole-exome sequencing to identify the genetic basis of DSS. Our study was approved by the Institutional Review Board of the Baylor College of Medicine. As shown in Table 2, after discrete filtering against dBSNP129 for variants with known minor allele frequencies <5% (according to the 1000 Genomes Pilot project), only 303 genes had rare or novel protein-impacting variants in both subjects. As an initial strategy, we kept genes in which variants corresponded to an autosomal recessive model (i.e. homozygous or compound heterozygote variants). There were 132 such overlapping genes. Given the high number of false-positive INDEL calls, we preferentially explored genes that showed at least one single nucleotide polymorphism (SNP). As shown in Table 2, only 17 genes shared by the two subjects showed rare or novel protein-impacting variants. Variants were visualized and compared with 12 other exomes of subjects with unrelated conditions. After keeping only high-quality variants (e.g. removing variants in repeat regions or variants seen in unrelated conditions that are likely false positives), and considering variants predicted to be pathogenic, only SLC29A3 variants remained. Subject 1 is heterozygous for p.Ser203Pro (c.607T>C) and p.Arg386Gln (c.1157G>A).

During these episodes, urticaria began midway through an infusion but resolved soon after the infusion was completed. In the four patients with recurrent urticaria, the episodes eventually became less frequent and less severe and finally stopped. In three patients (Patients 1, 5, and 6), the urticaria was accompanied by angioedema (thickening of the tongue and tightening of the throat) on a total of nine occasions and by moderate transient hypoxemia on three occasions.

      CasePreviousTesting: Serum CK levels 8,000 - 18,000 UI/l; Genetic testing also included DMD, FKRP, DM1, DM2;

      CaseGenotypingMethod: DNA was collected from peripheral blood or saliva samples. WES was performed and processed though a pipeline before aligning the reads and analyzing the candidate gene list for any variants using the various inheritance patterns. Screening was performed based on in silico predictors with a liberal threshold to filter variants before PCR amplification and Sanger sequencing confirmed the pathogenic mutations.

    1. Nine different mutations (c.494-1G>A, c.793-6C>G, c.793-5C>A, p.M1L, p.Y64X, p.A327P, p.W402X, p.P533L, and p.R628X) were identified. Computational analysis results supported the pathogenicity of novel mutations, suggesting improper splicing. Seven already-known polymorphisms were detected in the screened cohort as well.
