Huntington's Disease Research Paper

Decent Essays

Huntington’s disease is caused by genetic mutation. The mutation occurs on the HTT gene; the HTT gene contains the DNA used to code for a protein called Huntingtin. The HTT gene is located on the shorter arm of the 4th chromosome. The protein, Huntingtin, is primarily used in neurons in the brain and is also found throughout the body.
The mutation on the HTT gene is on a segment of the DNA; the sequence on this part of the gene is called CAG trinucleotide repeat. The mutation causes the CAG sequence to be repeated an abnormal amount of times. In a person without the mutation, the CAG sequence is repeated 10 to 35 times on the gene. In a person with Huntington's, the CAG sequence is repeated 36 to 120 times; people who have 36 to 40 repeats
