How does a person inherit Rett Syndrome

Rett syndrome is a genetic disorder. Most cases of Rett Syndrome occur in people with no history of this disorder in their family.This mutation is located on the twenty third chromosomes, which are the sex chromosomes. Females can use their second x chromosome instead of the affected one which is why females are less likley to get genetic diseases. This disease, however, has only been seen to affect females as males will most likley die before birth. Rett Syndrome is unlikley to be passed on from parent to child. It is more likley that there will be a random mutation. The parents can pass it on to their child, but this is extremly rare and doesn't happen that often. So any female has a chance to get Rett Syndrome.
