2014-08-04 · Classic Rett syndrome is most commonly caused by mutations in the MECP2 gene and is usually inherited in an X-linked dominant manner. The vast majority of cases are not inherited from a parent, but are due to a new mutation in the affected person. Treatment mainly focuses on the specific signs and symptoms of the condition. Se hela listan på rarediseases.org Symptomatic Rett Syndrome severity tends to increase in males, and mortality rates are higher, largely attributable to their single X-chromosome genetic status.

Rett syndrome (RS; MIM 312750) is a severe neurological disorder affecting exclusively females. Its prevalence is about 1 in 10 000 female births, and it is a prominent cause of profound mental handicap in women.

Clinical features. RTT is a severe neurodevelopmental disorder, mostly affecting females. However, there are also rare cases of boys and adult males with RTT (1). The most important clinical signs are impairment in cognition, motor control and communication skills.

Males with either classic or severe Rett syndrome have the same MeCP2 mutations that cause classic Rett syndrome in girls. Those boys who have been identified with less severe neurological and/or psychiatric manifestations carry mutations in the MECP2 gene that are not found in girls with any identifiable phenotypic abnormality of the central nervous system. Se hela listan på healthguideinfo.com It has been more than 50 years since Andreas Rett first described the unusual clinical entity that came to be known as Rett syndrome (Online Mendelian Inheritance in Man number 312750), and 20 years since the discovery that Rett syndrome is caused by mutations in X-linked MECP2. Coleman (1990) reported a possible case of Rett syndrome in a male, and Philippart (1990) reported 2 such cases.

9 Aug 2015 Rett syndrome (RTT) is a neurogenetic disorder in which a period of typical development is followed by loss of previously acquired skills.

In the United States, the disorder affects 1 in 10,000 girls by the age of 12.

Rett syndrome is a progressive neurodevelopmental disorder that almost exclusively affects females. Only in rare cases are males affected. Infants with Rett syndrome generally develop normally for about 7 to 18 months after birth. Thus, he suggested that it is the high male:female de novo germline mutation rate that explains the absence of affected males in Rett syndrome. Villard et al. (2001) identified a mutation in the MECP2 gene in only 1 of 5 families with RTT, suggesting an alternative molecular basis for the phenotype in the other 4 familial cases.

Gender and Cultural Factors The occurrence of Rett syndrome has been observed to exist fairly equally across all racial, ethnic, and cultural groups but has been noted to be significantly more common in female births as opposed to male births.
