Learn About Familial Hypertrophic Cardiomyopathy

What is the definition of Familial Hypertrophic Cardiomyopathy?

Familial hypertrophic cardiomyopathy is a heart condition characterized by thickening (hypertrophy) of the heart (cardiac) muscle. Thickening usually occurs in the interventricular septum, which is the muscular wall that separates the lower left chamber of the heart (the left ventricle) from the lower right chamber (the right ventricle). In some people, thickening of the interventricular septum impedes the flow of oxygen-rich blood from the heart, which may lead to an abnormal heart sound during a heartbeat (heart murmur) and other signs and symptoms of the condition. Other affected individuals do not have physical obstruction of blood flow, but the pumping of blood is less efficient, which can also lead to symptoms of the condition. Cardiac hypertrophy often begins in adolescence or young adulthood, although it can develop at any time throughout life.

What are the causes of Familial Hypertrophic Cardiomyopathy?

Mutations in one of several genes can cause familial hypertrophic cardiomyopathy; the most commonly involved genes are MYH7, MYBPC3, TNNT2, and TNNI3. Other genes, including some that have not been identified, may also be involved in this condition.

How prevalent is Familial Hypertrophic Cardiomyopathy?

Familial hypertrophic cardiomyopathy affects an estimated 1 in 500 people worldwide. It is the most common genetic heart disease in the United States.

Is Familial Hypertrophic Cardiomyopathy an inherited disorder?

This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Rarely, both copies of the gene are altered, leading to more severe signs and symptoms.

Hearts in Rhythm Organization Hypertrophic Cardiomyopathy Registry, Biobank and Imaging Data Repository (HiRO-HCM)

Summary: The Hearts in Rhythm Organization (HiRO) is a national network of Canadian researchers/clinicians, working towards a better understanding of the rare genetic causes of sudden cardiac death (SCD). The HiRO Hypertrophic Cardiomyopathy registry, biobank and imaging data repository (HiRO-HCM) is a multicenter study that will prospectively enroll patients with HCM as well as those carrying sarcomeric g...
