Is hypertrophic cardiomyopathy inherited?

Question: We are going to undergo fertility treatment and my husband suffers from obstructive hypertrophic cardiomyopathy. Could we do the treatment with his sperm or would it be advisable to use that of a donor so that our future son does not inherit the disease? Mayra (Madrid).

Answer: Although there are sporadic forms of hypertrophic cardiomyopathy, it is most often inherited in an autosomal dominant manner. This means that 50 percent of the offspring will inherit this alteration, affecting men and women equally.
