A. Hi, Thank you for the question! The short answer is no, no matter how many people have HD in your family, your risk is always the same – 50%. Because you have said your mom has HD, then the risk of her passing HD on to any of her children is 50%. Each child will have their own individual 50% risk. If for example there were 5 siblings at risk of HD, all 5 could get HD, all 5 could not get HD and be fine, or it could be a mix of HD and not. The 50% risk is like flipping a coin, someone might flip it and get a heads, some may flip it and get tails. I hope this helps a little, let us know if you need more help.
