I have a 50/50 chance of inheriting Huntington’s disease – should I take a test to find out? | Lillian Hanly

A coin toss could give me two completely different lives. But once I know the result there’s no going back I’ve spent most of my life knowing I may have inherited a faulty gene that would cause Huntington’s disease, a neurodegenerative disease that can be fatal.

Right now, I am happily ignorant of whether I carry the mutation or not. A coin toss could give me two completely different lives. Once I know the results, there’s no going back.

I’m 27 years old, and I’m starting to think seriously about my future, whether that is moving overseas or contemplating having children.
