The odds

My nan had huntingtons disease.
My auntie has it and she has a child who is aged 10, My aunties huntingtons is moving pretty rapidly, she'll need a wheelchair in the next 2-3years.

My dad may have huntingtons also, What's the odds that I'll have it?

Hi,

Your father is the son of this particular nan, right? Also, the aunt is your father's sister? Huntingon's Disease is a heritable disease, but there is still a chance that you won't get it. I believe that you should talk to your aunt or father about it. i'm sure that they will know much more about it than I do.

What do you think?

My dad said he doesn't know, And I don't see my auntie much. I researched it anyway and I have a 50/50 chance

That sounds about right. I did some research too and apparently there's just one gene (the Huntington gene) that is involved. In the disease situation, the gene is mutated, but your dad obviously carries this. I encourage you to learn as much as possible about this illness. You will therefore be able to recognise the signs of it early and will understand how to better cope with it. However, this isn't to say that you actually have the mutated version of the gene.
