    [Genetic Studies]

    Hi Everyone,

    My husband has HCM, his father died suddenly (they now think that he had HCM as well) and he has two cousins with HCM.

    I am new to the HCMA message board and hve been reading it daily for the past three weeks. I have seen many questions regardly the occurences of HCM in families but would like to know what studies have been undertaken regarding this. Are there any figures available as to the chance of passing this onto future generations.

    Thanks

    Sonja

    Dear Sonja

    HCM is genetic and they have identified about 10 different mutations so far. Each child will have a 50/50 chance of getting HCM.

    Sarah

    Thankyou for such a quick response. We actually live in Australia and I didn't expect to get such a quick response with the time differences.

    No wonder the chances are so high if they have identified 10 different mutations.

    We have a six year old son that had an echo when he was 2 (the echo was clear). We were told that he should have another when he is 10. Is it reccomended that this be done annually at this early age?

    Sonja,

    The reason HCM is genetic is that it's a dominant genetic trait. If you carry the gene, either you pass it on or you don't. (You only pass half your genes to your offspring. Their other parent passes the other half.) If you pass the gene, the child will eventually show HCM. I think it varies when this will show up, but it often is during puberty when so many other changes occur in the body. The current US standard for screening children is ever 12 - 24 months until they reach puberty, then every 12 - 18 months until fully grown. Lisa, Sarah...please correct me if I am wrong on this one. Sonja, I would definitely get him checked again. Good luck.

    Slight correction Reenie -

    Not evey person with the gene will express it. This is research that is still ongoing and I can not tell you why this happens.

    This means that a child can carry the gene never express it and then pass it on to his/her child who will develop the condition.

    Thanks, Lisa. I guess I knew that, just forgot. How else would it "skip" a generation?
