Answer

Hypertrophic cardiomyopathy is usually inherited in an autosomal dominant fashion with incomplete penetrance. Mutations in four genes that encode sarcomeric proteins—TNNT2, MYBPC3, MYH7, ­and TNNI3—account for approximately 90% of cases. [27] Most people with symptomatic hypertrophic cardiomyopathy will experience them at rest. Less often, a person with this disorder will experience an initial episode of VT or VF with significant exertion.
