Q: Are congenital heart defects hereditary? A: It depends on variables. There are a few syndromes with high frequency of specific heart defects that can have inheritance risk up to 50%. However, a complex inheritance patter is about 5% risk, which include any pattern of congenital heart defect, not necessarily the same one. In brief, they can be inheritable. Multifactorial inheritance is seen with most congenital defects, meaning they more likely to recur in future pregnancies if the first one is affected. Syndromic cases will have stronger genetic inheritance and more mendelian vertical transmission.   Keywords: congenital heart defects hereditary     Related FAQ: http://healthtopquestions.com/?p=3956 http://healthtopquestions.com/?p=3942 http://healthtopquestions.com/?p=3727
