DiseaseAssertion: MPS-IH
FamilyInfo: Proband was born to unrelated parents.
CasePresentingHPOs: Congenital hip dysplasia (detected at 2 months), systolic murmur, hepatomegaly, macrocrania, coarse facial features, umbilical hernia, corneal clouding, mild thoracic and lumbar kyphosis (HP:0001385, HP:0031664, HP:0002240, HP:0000256, HP:0000256, HP:0001537, HP:0007957, HP:0002751)
CaseHPOFreeText: Frequent episodes of upper airway inflammation, neuro-motor delay, palpable liver, mitral dysplastic valve, thickened and prolapsing flaps with moderate mitral valve insufficiency. MRI of the brain showed dilated perivascular Virchow-Robin spaces, in the peritrigonal site bilaterally and in the corpus callosum, and a slightly dilated ventricular system in the supratentorial area. Slight tibial valgus. X-rays detected an altered coxo-femoral joint with lateralization of the femoral head.

CaseBMT: Yes, UCB-HSCT & MUD-HSCT. First allo- HSCT from unrelated cord-blood-derived stem cells was at the age of 27 months. Six months later (33 months of age), she underwent a second HSCT from an HLA-matched unrelated donor. Normal IDUA activity was reported about 30 days post HSCT and progressively decreasing urinary GAG.

CaseNotHPOFreeText: This proband is believed to be an affected MPS-patient however, the proband did not have any obvious clinical symptoms to date (up to two years of age). The paper states that this attenuated MPS I case will need a long term follow up.
CaseEnzymeAssay: Proband identified by newborn screening. alpha-L-iduronidase activity in dried blood spot sample is 0.56 umole/L/Hr; this is below the study's DBS enzyme activity cutoff value of 3 umol/L/h
CaseUrineGAGs: Urine DMB GAG ratio is 65.7 mg/mmol creatinine. 4.76 ug/ml dermatan sulfate in urine (<0.41 ug/ml is the reference cutoff for dermatan sulfate in this study). 3.35 ug/ml heparan sulfate in urine (<0.8 ug/ml is the reference cutoff for heparan sulfate in this study). 0.17 ug/ml keratan sulfate in urine.

HCM16.1
CaseHCM16.1: Mixed ancestry
DiseaseAssertion: Hypertrophic Cardiomyopathy
FamilyInfo: N/A
CasePresentingHPOs: HP:0001639 (Hypertrophic cardiomyopathy)
HPOsFreeText: N/A
CaseNotHPOs: HP:0000819 (Diabetes mellitus)
NotHPOsFreeText: N/A
CaseAddInfo: N/A
CasePreviousTesting: See Table 1
CaseGenotypingMethod: DNA was extracted from the probands' blood, followed by sequencing of the coding regions and exon/intron boundaries of 15 genes associated with HCM. From there, they were amplified by PCR ampliication and variants were filtered by pathogenicity. Every unclassified variant was confirmed by Sanger sequencing afterwards.

CaseAddInfo: 3 other probands have the same genotype
CasePreviousTesting: See Table 1
CaseGenotypingMethod: DNA was isolated from peripheral blood. Most participants underwent testing from the Illumina Cardiomyopathy Sequencing Panel, which includes 46 cardiomyopathy related genes. For others, whole exome sequencing or Sanger squencing was used. After the results were returned, variants were filtered for pathogenicity and rarity.

CasePresentingHPOs: HP:0001639, HP:0002094 (Hypertrophic cardiomyopathy, Dyspnea)
HPOsFreeText: Max Left ventricular wall thickness of 19 mm, Left atrium diameter of 42 mm, Left ventricular ejection fraction of 64%

NotHPOsFreeText: N/A
CaseAddInfo: N/A
CasePreviousTesting: The ACM proband from Family B was genotyped for PKP2, DSP, DSC2, DSG2, JUP and CTNNA3; the HCM patient from Family B was genotyped for MYBPC3, MYH7, TNNI3 and TNNT2.
CaseGenotypingMethod: All patients in Family B were directly sequenced according to the found variants in CTNNA3 and MYH7. These variants were filtered for pathogenicity and prevalence and classified accordingly.
