'Huntington's disease'






Hi, this has been on my mind for sometime now, and I wanted to ask you
all a few questions. I have read an article at 'Huntington's
disease'.

Which says:
'Huntington's disease is transmitted as an autosomal dominant trait.
The disease results from changes (mutations) of a gene known as
"huntingtin" located on the short arm (p) of chromosome 4 (4p16.3). In
those with the disorder, the huntingtin gene contains errors in the
coded "building blocks" (nucleotide bases) that make up the gene's
instructions. The gene contains abnormally long repeats of coded
instructions consisting of the basic chemicals cytosine, adenine, and
guanine (CAG trinucleotide repeat expansion)....'

While it must be true, I wonder what you have to say about it. Do let
me know!
Regards,
Sherry
