Can I get Huntington's disease if my grandfather had it?

For example, if a child's grandparent has Huntington's disease, but the child's at-risk parent hasn't been tested, then the child has a 25% probability of having inherited the gene. If the parent doesn't have the expanded gene, then the risk drops from 25% to 0% - meaning there is no risk at all to the child.

What are the odds of inheriting Huntington's disease?

Each child of a parent with HD has a 50 percent chance of inheriting the HD gene. A child who does not inherit the HD gene will not develop the disease, and generally, they cannot pass it on to their children or other future generations.

Who is most likely to inherit Huntington's disease?

Although anyone can develop HD, it tends to run in people of European descent (having family members who came from Europe). But the main factor is whether you have a parent with HD. If you do, you have a 50% chance of also having the disease.
