Juvenile Huntington's Disease
Hi there,
I am reading up on Juvenile Huntington's disease, reagrding a child who is 17 years old with cerebral atrophy of unknown cause. I have read about Juvenile HD as it looks similar to this child's presentation. Want i want to know is, does a child with HD necessarily have to have an HD sympomatic parent? I realise one parent has to be a carrier of the affected alele, but do they necessarily develop HD themselves?

Dear Mary

Thank you for visiting

HD is a progressive chorea with an autosomal dominant inheritance and usually begins in the middle age. It is characterised by choreiform movements and mental deterioration leading to dementia. It is accompanied by atrophy of caudate nucleus and loss of certain brain cells with a decrease in the level of several neurotransmitters. The parent who carries the affected gene, does not necessarily develop HD.

Kind regards
