Rett Syndrome

Rett Syndrome

Rett Syndrome is a neurological disorder that is classified as an autism spectrum disorder by the DSM-IV.  It is found overwhelmingly in girls. In 1964, Dr. Andreas Rett first described Rett Syndrome. Development appears normal until sixteen to eighteen months of age. It is cased by a defective regulatory,  methyl CpG binding protein 2, (MECP2 gene) found on the X chromosome. Temporary regression follows during which the child loses communication skills and purposeful use of the hands. Then stereotyped hand movements, gait disturbances and slowing rate of head growth become apparent.
