Since they have two X chromosomes and one Y chromosome, these boys can potentially have the MECP2 mutation but still produce enough MeCP2 proteins to survive. Nearly all cases involving Rett Syndrome in boys involve a child who also has Klinefelterâs Syndrome.
The HTT mutation that causes Huntington disease involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks (cytosine, adenine, and guanine) that appear multiple times in a row. Normally, the CAG segment is repeated 10 to 35 times within the gene. In people with Huntington disease, the CAG segment is repeated 36 to more than 120 times. People with 36 to 39 CAG repeats may or may not develop the signs and symptoms of Huntington disease, while people with 40 or more repeats almost always develop the disorder.
