Prevalence of Rett’s Disorder
RS is less common than other PDDs.
RS prevalence range between 1:10,000 births and 1:15,000 births. As of 2002, little is known about its prevalence across different racial and ethnic groups.
50%–80% of children with Rett’s disorder will eventually develop epilepsy.
Males with pathogenic MECP2 mutations usually die within the first 2 years from severe encephalopathy, unless they have an extra X chromosome (often described as Klinefelter syndrome), or have somatic mosaicism.
Females can live up to 40 years or more. 14
RS prevalence occurs at 6-7 cases of Rett’s disorder per 100,000 girls15
