Q. Do both parents have to be carriers of Huntington’s disease to pass it on to a future child?

A. Hi Isaiah,

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

To answer your question it sounds like you are asking if both parents need to have HD for a child to be at risk. Only one parent needs to have the HD gene for their children to be at risk for inheriting the gene themselves. This article explains it a bit more. Has one of your parents been diagnosed with HD? HD can be really confusing, but I am here if you have more questions. Don’t hesitate to reach out.
