The Huntington disease does not skip a generation. The Huntington disease is cause by a genetic defect on chromosome 4 in the DNA.

The Cytosine, Adynine, Guanine, repeat many times that it's supposed to. In normal human being, The CAG repeats 10-28 times in a normal gene, but a person who is affected with the Huntington, their CAG is repeated 36-120 times. Even though the cell in the body has the gene, only the brain cells seem to be affected.
