Question

What triggers Huntington disease?

Answer 1

The HTT gene provides instructions for making a protein called huntingtin. Although the function of this protein is unclear, it appears to play an important role in nerve cells (neurons) in the brain. The HTT mutation that causes Huntington disease involves a DNA segment known as a CAG trinucleotide repeat .Aug 18, 2020

Huntington's disease is a progressive brain disorder caused by a single defective gene on chromosome 4 \u2014 one of the 23 human chromosomes that carry a person's entire genetic code. This defect is "dominant," meaning that anyone who inherits it from a parent with Huntington's will eventually develop the disease.
