Q. If your nan uncles aunties and mom have huntingtons does that mean that you will as well?
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.
