WebThe huntingtin gene (HTT or HD gene) tells your body how to build the huntingtin protein. You get one HTT gene from each parent. If you have Huntington’s disease, one of your parents passed on an HTT gene with a mutation (like a misprint in a book). It tells your body to create an unusually long protein. WebNov 17, 2011 · In the normal huntingtin gene, this sequence is repeated between 11 and 29 times. In the mutant gene, the repeat occurs over and over again, from 40 times to more than 80. This defect causes the resulting huntingtin protein to be malformed, prone to clumping in the brain and causing the death of nearby nerve cells.
