Fact Sheet 54: Cardiomyopathies - Cardiovascular Disease 2
Familial hypertrophic cardiomyopathy (FHCM) is a genetic condition causing thickening of the heart muscle surrounding the ventricles leading to a range of health problems.
There have been at least 11 different genes that have been found to be associated with a predisposition for FHCM when they are faulty. Most of these genes instruct the cells to contract the heart muscle (sarcomere proteins). The pattern of inheritance of FHCM is described as autosomal dominant.
