CaseCM1829: Male, 12 years diagnosis, Japan, Asian

CasePresentingHPOs: HP:0001639 (Hypertrophic cardiomyopathy)

HPOsFreeText: N/A

CaseNotHPOs: HP:0001939 (Abnormality of metabolism/homeostasis)

NotHPOsFreeText: Neuromuscular disease, Malformation syndromes

CaseAddInfo: No family history of cardiomyopathy or sudden death, Proband found in Supplementary Table 2, Variant is asserted as novel, Mother and father are both negative for this variant

CasePreviousTesting: 8 patients with HCM and one with RCM were analyzed by NGS for the eight sarcomere-encoding genes and MYP.

CaseGenotypingMethod: Probands were subject to PCR amplification and direct sequencing of 64 cardiomyopathy-associated genes, including the eight sarcomere-encoding genes. The variants were then filtered for rarity and tested for pathogenicity.

Variant: NM_000257.3:c.2459C>A (p.Ala820Asp)
