Inheritance. Although Rett syndrome is a genetic disorder, less than 1 percent of recorded cases are inherited or passed from one generation to the next. Most cases are sporadic, which means the mutation occurs randomly, and are not inherited. A few families have been described with more than one affected family member …
How is Rett syndrome transmitted?
A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. The inheritance is dominant if one copy of the altered gene in each cell is sufficient to cause the condition. Males with mutations in the MECP2 gene often die in infancy.
What is the most severe form of autism?
Autistic disorder was the most severe. Asperger’s Syndrome, sometimes called high-functioning autism, and PDD-NOS, or atypical autism, were the less severe variants. Childhood disintegrative disorder and Rett Syndrome were also among the pervasive developmental disorders.

What type of mutation is Rett syndrome?
Most cases of Rett syndrome are caused by a change (also called a mutation) in a single gene. In 1999, NICHD-supported scientists discovered that most classic Rett syndrome cases are caused by a mutation within the Methylcytosine-binding protein 2 (MECP2) gene. The MECP2 gene is located on the X chromosome.
