@Mitchell2011Keenan with the brain and it's processes with coordination and logical/emotional reasoning. Even more concerning is the phenomena of Anticipation, where the CAG will actually expand from successive passing of the gene. This means it is possible to have Huntington's Disease crop up in a family without it ever being present before.

@Mitchell2011Keenan CAG stands for Cytosine,Adenine and Guanine. They are molecules that make up the DNA for living things along with Thymine/Uracil depending if it's DNA or RNA. Huntington's Disease occurs when Chromosome #4 has more than 35 CAG repeats, because this particular portion of the gene codes for Huntingtin, a protein sequence has no known purpose but gathers in the brain. The issue is when the CAG repeat extends beyond 35, the protein it produces becomes elongated and interferes

@Allibaby78 CAG repeat, does CAG stand for something?
-
As the gene is passed on from one generation to the next, the number of repeats - called a CAG repeat expansion - tend to get larger. The larger the number of repeats, the greater your chance of developing symptoms at an earlier age. Therefore, as the disease is passed along in families, it becomes evident at younger and younger ages

Huntington's disease is caused by a genetic defect on chromosome #4. The defect causes a part of DNA, called a CAG repeat, to occur many more times than it is supposed to. Normally, this section of DNA is repeated 10 to 35 times. But in persons with Huntington's disease, it is repeated 36 to 120 times.
