    General Discussion
    Rett Syndrome is a rare neurodevelopmental disorder that appears to occur almost exclusively in females but can occur rarely in males. Infants and children with the disorder typically develop normally until about 7 to 18 months of age, when they may begin to lose previously acquired skills (developmental regression), such as purposeful hand movements and the ability to communicate. Additional abnormalities typically include slowing of head growth (acquired microcephaly); development of distinctive, uncontrolled (stereotypic) hand movements, such as hand clapping, rubbing, or wringing; and impaired control of voluntary movements required for coordination of walking (gait apraxia). Affected children also typically develop autistic-like behaviors, breathing irregularities, feeding and swallowing difficulties, growth retardation, and episodes of uncontrolled electrical activity in the brain (seizures).

    Rett Syndrome results from a mutation (change) on the X chromosome that is transmitted as an X-linked trait. However, most cases are thought to represent new mutations that appear to occur spontaneously (sporadically) for unknown reasons. In some affected females, the disorder may result from mutations of a gene known as MECP2 that is located on the long arm (q) of chromosome X (Xq28). The MECP2 gene is thought to play an essential role in brain development.
