    1. DNA extraction, PCR, single strand conformation polymorphism and/or denaturing high-performance liquid chromatography, heteroduplex analysis and sequencing Screening for mutations in the SDHD, SDHB and SDHC genes was performed in all patients. RET and VHL were analysed in all patients with abdominal pheochromocytoma/paraganglioma and a subset of patients with head and neck paraganglioma (27/36). Venous blood samples were drawn for all participants and DNA was extracted from whole blood (DNA purification kit, Gentra Systems Inc, Minneapolis, Minnesota, USA). The different exons and intron–exon boundaries of the three SDH and the RET and VHL genes were amplified by PCR. Screening for mutations was performed by single strand conformation polymorphism (SSCP), and heteroduplex analysis, as described [15] or by denaturing high performance liquid chromatography (dHPLC) analysis, using the WAVE 3500 HT system (Transgenomic, Inc., Omaha, Nebraska, USA). Fragments showing abnormal migration were reamplified and sequenced on a CEQ2000 capillary sequencer (Beckman Coulter, High Wycombe, UK).

    1. DNA analysisBoston University School of Medicine's laboratory performed CLIA-approved DNA full sequence analysis of the VHL gene for the proband and site-specific DNA analysis for the proband's mother. Genomic DNA was extracted from peripheral blood lymphocytes using standard procedures. Sequence analysis consisted of polymerase chain reaction (PCR) amplification and automated fluorescence sequencing of all three VHL exons. Multiple ligation probe amplification (MLPA), using the VHL kit from MRC-Holland was also performed. The VHL kit from MRC-Holland detects approximately 97% of all deletion mutations in the VHL gene.

      ArticleReferenceSequence: Not specified - Assumption: variants assumed to have been documented by the author under reference sequence NM_000551.3.

      GenotypingMethod: Analysis consisted of polymerase chain reaction (PCR) amplification and automated fluorescence sequencing. Additionally, multiple ligation probe amplification (MLPA). Western blot analysis was also performed using horseradish peroxidase (HRP)-conjugated secondary antibodies and an enhanced chemiluminescence kit.

    2. We report the case of a 15-year-old boy with the diagnosis of aggressive GH-PRL pituitary macroadenoma and a family history of VHL disease. Pituitary resection was performed, although complete excision of the lesion could not be confirmed by the neurosurgeon. A control MRI was done 6 months after surgery and the pituitary lesion was similar to the presurgical image. A second operation allowed partial resection of the tumour followed by targeted radiotherapy.

      Case: M, 18Y0M, Ethnicity Unknown

      DiseaseAssertion: VHL

      FamilyInfo: The family history revealed VHL in his mother, who died at the age of 40, and in his maternal aunt and grandmother, deceased at 30 and 33 years, respectively. His mother was operated on three times for cerebellar hemangioblastomas, the first at 13 years of age. She had also been treated for bilateral retinal hemangioblastomas since the age of 19. In addition, she had surgery for a renal tumor at the age of 32 and also had pancreatic cysts. She died of the diffuse hemangioblastomas in the posterior fossa. Variant is stated to be previously identified in the family but it is not clear which members have been genetically tested.

      CaseHPOFreeText: Referred at the age of 15 for decreased visual acuity of the right eye. Growth failure with short stature for age and lack of pubertal development was noted. This was confirmed by ophthal-mologic examination which also showed bitemporal quadranopsia. Two retinal vascular lesions had already been diagnosed and photocoagulated. Cerebral MRI examination visualized a voluminous pituitary adenoma (confirmed pathologically) with suprasellar extension compressing the optic fibres invading both cavernous sinuses. It also confirmed two small cerebellar hemangioblastomas. On follow-up, MRI showed a persistent pituitary adenoma (confirmed by pathology) with numerous mitoses. A cystic part of the main hemangioblastoma was also noted in the right cerebellum image.

      CaseNotHPOFreeText: No renal lesion was found on ultrasound examination. Renal ultrasound examination was persistently normal.

The following report is a 2011 updated pedigree on the previously reported Tisherman kindred. At the time of this study, 43/49 patients have undergone mutational analysis revealing the VHL familial mutation (Y112H) and 35/49 patients have clinical VHL manifestations. Phenotypic cumulative lifetime risk was 71% for Pheo/PGL, 15% for hemangioblastoma, 33% for retinal angioma, 3% for renal cell carcinoma, and 3% for pancreatic cysts. 6 members of the family (all deceased; 4 males, 2 females) had suspected VHL and 2 (males) of these were suspected to have had Pheo/PGL.

    1. Mutation analysisAll germ-line mutations were documented by the results of genetic testing performed in Florence according to standardized protocols. DNA was extracted from the peripheral blood leukocytes of each patient using the NucleoSpin Blood L kit (Macherey-Nagel, Düren, Germany) and analyzed for germ-line mutations of SDHA (all exons), SDHB (all exons), SDHC (all exons), SDHD (all exons), SDHAF2 (all exons), MAX (all exons), TMEM127 (all exons), and VHL (all exons). For each gene, coding regions and exon–intron boundaries were amplified by PCR as described previously (Astuti et al. 2001). PCR products, purified using a commercial kit (PCR purification kit, Qiagen), were subjected to 2% agarose gel electrophoresis with ethidium bromide staining and subsequently sequenced with a genetic analyzer (ABI PRISM 310; Applied Biosystems, Milan, Italy).Multiplex ligation-dependent probe amplification reactionsPatients younger than 50 years, whose DNA sequencing was wild type for SDHB, SDHC, SDHD, SDHAF2, and VHL, underwent analysis for genomic rearrangements in these genes. For this purpose, we used commercial kits for multiplex ligation-dependent probe amplification (MLPA)-based assays (SALSA MLPA P016B VHL and SALSA MLPA P226 SDHD; MRC-Holland, Amsterdam, The Netherlands) following the manufacturers' instructions.Amplification products were diluted in HiDi formamide containing 500TAMRA internal size standards (MRC-Holland) and then separated by size using an ABI PRISM 310 Genetic Analyser (Applied Biosystems). Electropherograms were analyzed using Coffalyser MLPA DAT software (MRC-Holland).

Abdominal CT scan revealed cystic lesions throughout the parenchymatous portion of the pancreas, suspected to be related to VHLs. Together, supported the diagnosis of VHL. The patient underwent surgery of the brain, and radiotherapy which proved to work in small degrees.

    1. Interestingly, one carrier of the deletion developed bilateral breast cancer at age 46 and 49. First cancer was diagnosed at the age of 46 in her right breast. The patient was treated by mastectomy with postoperative chemotherapy (CMF). Histopathological examination revealed invasive ductal breast carcinoma of 1.8 cm size. The tumor was ER- negative, and PR-negative (HER2 was not analyzed). A metastasis in 1 axillary lymph node was found. There was no evidence of distant metastases. The tumor was classified as T1c pN1a M0, stage IIA; grade G2. Three years later, at the age of 49, she was diagnosed with cancer of her left breast. It was an invasive ductal carcinoma of 2.0 cm size. The tumor was ER-positive, PR-positive, and HER2-negative. There was no evidence for lymph-node or distant metastases. The tumor was classified as T1c pN 0 M0, stage IA, grade G2 and treated with mastectomy and tamoxifen. Ki67 expression was not tested. At present, 9 and 6 years after treatment of the breast cancers there is no evidence of breast cancer recurrence. However at age of 54, lesions typical for VHL disease including cerebellar haemangioblastoma and renal cell carcinoma were diagnosed in the patient.

    1. Genomic DNA was isolated from peripheral blood samples by Qiagen DNA Blood mini kit (Qiagen, Hilden, Germany) following the manufacturer’s instruction. Genomic DNA (50–100 ng) was amplified by PCR in a standard PCR buffer containing 200 μM per each dNTPs, 1.5 mM MgCl2, 0.25 units of Taq polymerase and 0.2 μM per each primers with the thermal cycling program of 95 °C for 30 s, 60 °C for 30 s and 72 °C for 30 s for 30 cycles. PCR products were purified and sequenced in an ABI 3730 automated sequencer (ABI, Foster City, CA, USA). The primer pairs used for the amplification of the three exons and their flanking introns of VHL gene were 1F: 5′-IndexTermggtggtctggatcgcgga-3′ and 1R: 5′-IndexTermggcttcagaccgtgctatcg-3′ (product size 418bp), 2F: 5′-IndexTermgtggctctttaacaacctttgc-3′ and 2R: 5′-IndexTermcctgtacttaccacaacaaccttatc-3′ (product size 208 bp), and 3F: 5′-IndexTermgcaaagcctcttgttcgttc-3′ and 3R: 5′-IndexTermcaaaaatgccaccaccttct-3′ (product size 504 bp).

Recombinant CTH was expressed and the proteins were purified and the levels detected. The activity of the T67I mutant was 0.6 μmol min−1 mg−1 protein, 3.5-fold lower than the wild-type, with H2S generation from homocysteine and cysteine showing similar decreases of 4-fold and 2-fold respectively. The Q240E mutant was significantly lower, with only 0.03 μmol min−1 mg−1 protein and no detectable H2S generation. See Purification and Kinetic Properties of the Patient Mutations T67I and Q240E for details.

      Furthermore, the variant was tested for PLP responsiveness. While the wild-type alleles exhibited ~80% content, the T67I and Q240E variants only displayed 19% and 0.3-1% saturation respectively. See Figure 3 for details.

      NonPatientCell: EFO:0001182 (HEK293 Cells)

      GeneFunction: GO:0008233 (Peptidase activity)

      GeneAlteration: HEK293 cells were grown and 8 missense mutations were identified and generated by PCR-mutagenesis. The human mutant cDNAs were transfected into the cells using the calcuim-phosphate coprecipitation method and examined.

      FunctionalEvidence: When HEK293 cells were transfected with wild-type and mutant human cDNA for PHEX, the resulting cells were subject to immunoblotting to determine the protein levels in both the cell lysate and the media of cells. All the variants and the wild-type showed presence in the lysate at various levels, but C85R, G579R, G579V, S711R, and A720T were all devoid of any secreted protein in the media. Ananlysis of these cells also showed possible rescue by growing transfected cells at 26 C, thus glycosylating and maturing the proteins. The endopeptidase activity of the wild-type and variants were also compared, with D237G and Y317F mutant proteins exhibiting 50–60% of wild-type activity; E581V and S711R also displayed nearly undetectable activity. This displayed that the disease causing mechanism could be related to loss of function of peptidase activity or cellular trafficking. Evidence is found under "Results".

      NonHumanModel Mus Musculus

      GeneAlteration The knock-in strain was generated by homologous recombination of the targeting vector with 129Sv/J embryonic stem cells genome. A 450-bp DNA segment encompassing 5′ UTR and exon 1 of the CASQ2 was used to screen RPCI-21 PAC mouse genomic library. Positive clones were sequenced to define the structure of an 8.5-Kb region encompassing promoter, exon 1, and part of intron 1 of mouse CASQ2. This region was cloned in 3 parts and assembled into the targeting vector pFlrt (supplemental Figure I). The linearized targeting vector was electroporated into 129Sv/J embryonic stem cells. The clone selected with G418 and gancyclovir was injected into C57BL/6NCrL blastocyts and transferred to pseudopregnant CD-1 females. Genotype was determined by sequencing of DNA extracted from tail biopsy specimens (DNasy Tissue Kit, Qiagen).

      CasePreviousTesting: Chromosome analysis, microdeletion 22q11.2 testing, chromosomal microarray analysis, fragile X testing (FMR1) and methylation sensitive MLPA for chromosome 11 and 7 loci (Silver-Russell syndrome) testing were unremarkable and normal.

      CaseGenotypingMethod: WES

      Sanger sequencing was used to confirm the mutation and to exclude the presence of the mutant in the parents.

      The WES identified a heterozygous mutation in ARID1A, a gene that is associated with Coffin-Siris syndrome. The mutation was a 6 bp duplication in (NM_006015.4:c.489_494dupCGCCGC, p.[(A164_A165dup)]. It was maternally inherited, and the mother was not noted to have behavioral abnormalities. In addition, the WES revealed 18 different mutations in 12 genes (Supplemental Table 1). Most of these were ruled out due to high frequencies in the control population in homozygoues state, or the genes were associated with disease entities that had disparate phenotypes than the those presenting in the proband.

      AddCaseInfo:

      VariantEvidence: No variant evidence to confer alteration of FBXO11 function or pathogenicity. Furthermore, the presence of a VUS in ARID1A that is responsible for Coffin-Siris syndrome, which has many overlapping phenotype, cannot be ruled out as contributory, even in the absence of an strongly overt phenotype in the mother. Subtle behvioral phenotypes could be present, and she was not fully evaluated to rule out and behavioral abnormalities. Albeit, this mutation has arisen in another unrelated individual, de novo, in Martinez et al., 2017 (PMID: 27620904 ), as well as one patient, de novo in the DECIPHER DDD study (case 325596).Therefore, I am downgrading the score but minimally.

    1. All nine affected individuals presented with various skeletal dysplasias. In four families (A and C–E), X-rays revealed severe platyspondyly leading to disproportionate stature (Figure 1). Lumbar gibbus and kyphoscoliosis were observed in families C and D, respectively. Three individuals (from families D and E) had cervical malformations and a hypoplastic odontoid peg with cervical instability. Short stature was also present in families A and B but appeared to be the result of limb shortening. Metaphyseal abnormalities of the long bones were found in families A and E, whereas families B–D showed epiphyseal abnormalities (Figure 1). Brachydactyly was observed in affected individuals from families A, B, and D. In addition to showing skeletal abnormalities, all affected individuals in families B and C had intellectual disability (ID). This could not be assessed for individuals A:II-1, E:II-1, and E:II-2 because of their early death at 7 weeks, 6 months, and 10 months of age, respectively. Both siblings of family B were severely disabled and unable to speak and are currently wheelchair bound. Dysmorphic facial features were non-discriminatingly mild but included coarse facial features, a prominent nose, and full cheeks in almost all affected individuals (Figure S1). A single palmar crease was also observed in six of nine affected individuals. A striking phenotype present in three of the five families was T-cell-negative SCID. Affected individuals from families A and B showed a lack of T cells, whereas B cell numbers were normal (Figure 4). Family E showed idiopathic CD4+ lymphopenia and an absolute lack of naive T cells (both CD4+CD45RA+ and CD8+CD45RA+ T cells were missing). In families B and E, a typical skin rash prompted further evaluation of the blood cells. Maternal T cells were excluded, and the oligoclonal T cell reaction found in the presence of eosinophilia was compatible with an Omenn-like presentation of SCID.1,2 Worth mentioning are also the liver cysts seen in affected individuals from families A and E. Although the phenotypes were widely variable and partly contrasting (e.g., severe versus no ID, severe versus mild platyspondyly, and epiphyseal versus metaphyseal changes), all major malformations and features occurred in three organ systems only: the immune system, the skeleton, and the neurological system. All together, we classify these five families as having phenotypic variability of an EXTL3-related neuro-immuno-skeletal dysplasia phenotype. The affected individuals from families A and E died in early infancy, whereas the others are currently between 2 and 38 years of age. Individual III-1 from family D died at 30 years of age from a unknown cause. Table 1 gives an overview of the most affected organ systems in all affected individuals. Detailed case reports and clinical data for each affected individual can be found in the Supplemental Note.

      AddCaseInfo: The parents of this individual were consanguineous and of Moroccan origin and were found to be heterozygous carriers of the variant. The individual's younger sister (TTD275HE) was also affected and homozygous for this variant. She also presented with brittle hair, dysmorphic features, mild developmental delay, microcephaly, mild difficulty swallowing, no failure to thrive, cheerful character, mild ichthyosis, additional left thumb, no recurrent infections and growth retardation

      VariantEvidence: This variant has been identified in two other individuals (other than this proband and her sibling) of Moroccan origin, giving rise to the question of a founder mutation. This proband is not being scored since the variant has already been awarded default points previously.

    1. To confirm pathogenicity of the c.68G>T human mutation and to provide an informative model of the human disease, this mutation was introduced into the orthologous mouse gene using CRISPR/Cas9 gene-editing (protein ID: 94%, Figures S4A and S4B). PlaaG23V/G23V

      ExperimentName: Plaa G23V/G23V homozygous mice

      HumanPhenotype: HP:0012448

      ModelEvidence: Plaa G23V homozygous mice are viable past birth, but cannot survive past 6 months without assistance of feeding, etc (Figure 3B). The mutant show microcephaly (reduced brain volume, Figure 3C). MRI performed on the G23V homozygous mice compared with control wildtype littermates show significantly reduced corpus callosum and cerebellum volumes, indicating reduced white matter (Figure 3E). The cerebellum is noted to have disrupted foliation (figure S5C). The authors note early onset neurodysfunction, including tremor and muscle weakness , showing severe hindlimb clasping, reduced grip strength and altered gait detectable from P14 (Figure 3 and Figure S5).

      They authors even went on to cross the Plaa G23V heterozygous mice with Plaa homozygous null mice to create Plaa G23V/- mice that have a more severe phenotype that the homozygous Plaa G23V homozygous, but less severe that the Plaa homozygous null (plaa-/-).

      Reason: This mouse model represents a patient derived mutation that was knocked directly into the mouse Plaa locus, through use of Crispr/Cas9 gene editing. The mice were shown to have reduced Plaa protein expression (reduced by 70%), and the development of phenotypes consistent with phenotypes observed in individuals. I have therefore, increased the score based on the evidence provided.

      CaseAddInfo: Family is consanguineous, The MYPBC3 variant was the only one to segregate with the disease, with the CACNB2 variant also being present in individuals with "severe" forms of the disease. CACNB2+ MYH7- individuals showed no symptoms of cardiomyopathy, supporting a modifying effect leading to the clinical heterogeneity of this family, MYBPC3 variant leads to a premature termination and a loss of 49 amino acids which is predicted to undergo NMD but is also associated with incomplete penetrance

      CasePreviousTesting: Marked hypertrophic septum (27  mm) and a left-ventricular outflow obstruction (LVOTO) of 32  mmHg, Clinical features in Table 1, No members showed Brugada syndrome phenotypes, Proband also has polymorphisms in TGFB1 and AKAP9 but no other affected family member contains them suggesting a benign pathogenicity

      CaseGenotypingMethod: Genomic DNA was extracted from peripheral blood. PCR amplification was performed and sanger sequencing was performed for MYH7 and MYPBC3 mutations. After positive confirmation of the MYBPC3 mutation, RAAS genes were genotyped for a possible modifying effect. Negative findings led to a targeted NGS for the index patient using all known 104 causing/closely related genes of cardiomyopathy and chanelopathy. These variants were then filtered and analyzed for pathogenicity and confirmed in family members via Sanger sequencing.

      GeneAlteration: Samples were collected from deltoid muscle biopsy of control individuals and LGMD2C individuals with the 525delT founder mutation. No further alteration necessary.

      FunctionalEvidence: TUNEL staining was perfomed on muscle samples from LGMD2C patients and healthy controls to test for cell apoptosis. No positive staining was detected in any control individuals while it was commonly found in the patient muscle. This indicates that a result of SGCG disruption is increased cellular apoptosis likely contributing to the myofiber degeration and muscle atrophy seen commonly in LGMD patients.

      CasePresentingHPOsFreeText: apo-B plasma levels <2% of normal and > 50% acanthocytes; total cholesterol 1.27 (normal range 4-6.5 mmol/l), triglyceride 0.3 (normal range 0.3-1.8 mmol/l), apoB 1.5 (normal range 60-140 mg/dl), “virtually no LDL”; diagnosed with “homozygous” (i.e. biallelic) familial hypobetalipoproteinemia because both parents (AD and PD) had total plasma cholesterol and apo-B levels below the 5th percentile. Designated as the proband in the paper. However, only one variant identified (note that full gene sequencing was not performed”), and therefore PD (mother of DD) was added as the proband here as she is heterozygous for the variant and has lipid levels consistent with this.

      PresentingNotHPOsFreeText: No neurological or retinal disease.

      CasePreviousTesting: On Western blot a truncated species of apo-B was found in the VLDL/chylomicron fraction (fig. 3), predicted based on size to be at the 5’ end of exon 26. The protein was absent from the HDL or infranate fractions.

      CaseGenotypingMethod: Genomic DNA was digested with a panel of restriction enzymes and Southern blotted. Based on truncated apoB size (detected on Western blot), the variant was predicted to be at the end of exon 26. Approximately 1.7 kb of genomic DNA including exon 26 was amplified by the polymerase chain reaction (PCR), cloned into M13, and sequenced.

Patient UB612 (IV-1) was diagnosed with severe BMF and monosomy 7 without BM dysplasia at the age of 13 months. Transplantation was planned but eventually cancelled because his blood cell counts improved spontaneously. This patient is now 5 years old, without residual cytopenia or monosomy 7. His mother, patient UB609 (III-2), experienced a rather similar story 32 years previously; when she was 13 months old she was diagnosed with severe AA and BM transplantation was planned, which was also cancelled due to spontaneous improvement. Although they were not included in our IBMF cohort, we managed to investigate more patients in this family. The mother’s sister (III-3) also had early transitory pancytopenia, and both sisters, now aged 33 and 37 years, are doing well. Interestingly, the grandmother (II-2) had a cerebellar atrophy with ataxia, a nystagmus and the SAMD9L mutation found in her oral swab, whereas her own mother (I-2) also had the same neurological phenotype but could not be genetically explored.

    1. Patient 1 The first patient had no familial history of VHL disease and was 21 years old when he experienced a sudden right hearing loss. The resulting cophosis was irreversible. The radiological work-up revealed an osteolytic mass of the right temporal bone of heterogeneous signal on both T1- and T2-weighted images (Fig. 1), consistent with the diagnosis of endolymphatic sac tumor. The tumor invaded the otic capsule and the petrous apex but did not extend in the cerebellopontine angle. Its mean tumor diameter (MTD) at diagnosis was approximately 2.6 cm (formula—MTD = (length×width×height)1/3MTD = (length×width×height)1/3 {\hbox{MTD = }}{\left( {{\hbox{length}} \times {\hbox{width}} \times {\hbox{height}}} \right)^{{1/3}}} ) [16]. The rest of the neurological exam was normal and a conservative management was decided. During follow-up, the patient suffered from other manifestations of VHL disease: retinal and central nervous system hemangioblastomas, pheochromocytoma, renal tumors, and pancreatic cysts. The germline mutation of the VHL gene was also identified (c.337C>T, p.Arg113X). After 20 years of radiological surveillance, the size of his endolymphatic sac tumor remains stable (Fig. 2). Apart from his deafness, the patient does not suffer from any vestibular symptoms and his facial function is normal (House and Brackmann grade I).
