What are the causes of hypertrophic cardiomyopathy?

Cardiomyopathy : Hypertrophic cardiomyopathy is usually inherited within families due to abnormal genes causing irregular heart muscle growth.

Genes and others: About half of patients with hypertrophic cardiomyopathy are due to mutations in genes encoding cardiac muscle proteins or sarcomeres. Few are due to errors in metabolism such as Fabry's disease due to a lack of enzyme( galactosides) and the other half the cause is unknown.The genetic group is familial and autosomal dominant-50% chance of having defective gene in a family member
