Infants with Rett syndrome generally develop normally for about 7 to 18 months after birth. At this point, they lose previously acquired skills developmental regression such as purposeful hand movements and the ability to communicate.

Additional abnormalities occur including impaired control of voluntary movements ataxia and the development of distinctive, uncontrolled hand movements such as hand clapping or rubbing.

Some children also have slowing of head growth acquired microcephalyAffected children often develop autistic-like behaviors, breathing irregularities, feeding and swallowing difficulties, growth retardation, and seizures.

Most Rett syndrome cases are caused by identifiable mutations of the MECP2 gene on the X chromosome and can present with a wide range of disability ranging from mild to severe. The course and severity of Rett syndrome is determined by the location, type and severity of the MECP2 mutation and the process of random X-inactivation see Causes section below.

Many researchers now consider Rett syndrome as part of a spectrum of disease relating to mutations of the MECP2 gene.

Another disorder, MECP2 duplication syndrome, has recently been described in the medical literature.
