The Rett syndrome in males.
Two young males in their thirties are reported with a clinical history and examination indistinguishable from typical females with the Rett syndrome. Both had normal early development. The first patient had a regression by the end of the second year. He was late in walking, had prominent hand-wringing from the age of 4 years, and non-progressive dystonia from the age of 14 years. He is still ambulatory. Seizures which started at the age of 18 months have been easily controlled. The second patient has had a severe seizure disorder since the age of 7 months. In his early teens, he lost ambulation and his height and weight fell below the 2nd percentile. He has severe foot dystonia without spasticity. Both patients have a normal head size and no evidence of atrophy on a CT scan of the brain. Both had kyphoscoliosis in their teens. It is difficult to evaluate the incidence of such cases. Little attention being paid to the normal early development, they hide behind vague diagnoses such as cerebral palsy, static encephalopathy, and behavior disorder. Dystonia is often confused with spasticity, the lack of paralysis is not appreciated, apraxia and hand wringing are assumed to be self-stimulatory behaviors.
