About Genetic Cardiomyopathy

Cardiomyopathy can have many different names and causes. At the Genetic CardioMYopathy Awareness Consortium, our focus is on cardiomyopathy that is inherited, or passed from one family member to the other. There are 55-75 genes that are known to cause genetic based cardiomyopathy.

Close to half of all cardiomyopathy cases have some type of genetic basis or are inherited but only a very small percentage of diagnosed cardiomyopathy patients are ever asked to get genetically tested by their cardiologists even though their governing organizations recommend genetic testing. If you are interested in exploring genetic testing go to Support For Your Journey.

To learn more about cardiomyopathy and the different types of cardiomyopathies (all can have a genetic basis) take a look at the information below.

Cardiomyopathy Overview

All forms of cardiomyopathy have a few things in common:
