Are genetics involved if a child has a dilated cardiomyopathy?

Yes, in some cases: Nearly 20 % of cases of dilated cardiomyopathy have a familial basis.

Could be: There are several genetic locations have been identified in patients with dilated cardiomyopathy which can be mutation or inhereted.

Frequently: Current evidence supports that at least 35% of patients with nonsyndromic dilated cardiomyopathy are familial (probably genetic) or genetic in etiology. Defects in contractile proteins, sarcolemmal proteins, and ion channel proteins have been shown to cause dilated cardiomyopathy. Most have an autosomal dominant inheritance pattern, but there are autosomal recessive and x-linked defects.
