I found out more information. To qualify for genetic testing, patients must have suspected or confirmed hypertrophic cardiomyopathy, and the test needs to be ordered by a hypertrophic cardiomyopathy (HCM) specialist. Hypertrophic cardiomyopathy usually is passed down through families. That means it's inherited. People with one parent with hypertrophic cardiomyopathy have a 50% chance of having the gene change that causes the disease.

Parents, children, or brothers or sisters of a person with hypertrophic cardiomyopathy should discuss this test with their cardiologist or HCM specialist.

@ipizza, since your mother was diagnosed with “a thickened septal wall” and you are experiencing some symptoms characteristic of HCM, you should speak to a cardiologist about ordering the test for you. Was your mother diagnosed with HCM or HOCM? Did she have heart surgery?
