A. Hi Eric,

Thank you for reaching out to HDYO with your question. My name is Chandler and I work with young people and families in the US to answer questions and provide support.

Your friend is lucky to have someone that cares about him as much as you do. If your friend got tested for Huntington’s Disease (HD) and tested negative, then he won’t develop symptoms and his son and future children are not at risk. HD also can’t skip a generation. Once it has stopped in a family line (i.e your friend testing negative has stopped it for his family line from here on out) it is done for that family.

If he is concerned about anything his son is experiencing he should see his primary care doctor to assess for any other medical issues.

I hope this information helps. Please don’t hesitate to reach out with any other questions.

Take care,
