100 RTT patients (98 females, 2 males) with MECP2 mutations underwent baseline neurological evaluation (KKI-RTT Severity Scale) and QTc measurement (standard 12 lead electrocardiogram) as part of our prospective natural history study.
RTT is usually associated with normal development in infancy followed by loss of acquired skills and evolution of characteristic hand wringing movements and episodes of hyperventilation.A panel of 25 female and 22 male patients with a clinical diagnosis of AS and no molecular abnormality of 15q11-13 were screened for MECP2 mutations and these were identified in four females and one male.

Rett syndrome is a neurodevelopmental disorder that affects females almost exclusively, and in which eight common point mutations on the X-linked MeCP2 gene are knows to cause over 70% of mutation-positive cases.
Rett syndrome (RTT) is a severe neurodevelopmental disorder caused, in most classic cases, by mutations in the X-linked methyl-CpG-binding protein 2 gene (MECP2).
Rett syndrome (RTT), caused by mutations in MECP2 (encoding methyl CpG binding protein 2), and Angelman syndrome (AS), caused by maternal deficiency of chromosome 15q11-13, are autism-spectrum neurodevelopmental disorders.
Rett syndrome is frequently caused by a mutation in methyl-CpG-binding protein (MECP2) gene, localized on chromosome Xq28, whereas Angelman syndrome is frequently caused by different genetic anomalies at chromosome 15q11-q13 (deletions, uniparental disomy, imprinting center mutations, ubiquitin E3 ligase [UBE3A] gene mutations).
Rett syndrome (RTT) is an X-linked postnatal neurodevelopmental disorder, which is primarily caused by mutations in the gene encoding methyl-CpG binding protein 2 (MeCP2).
Rett syndrome (RTT) is a debilitating neurological condition associated with mutations in the X-linked MECP2 gene, where apparently normal development is seen prior to the onset of cognitive and motor deterioration at 6-18 months of life.
Rett syndrome (RS) is an X-linked dominant neurodevelopmental disorder caused by mutations in MECP2 (Xq28) and characterized by normal development until 6-12 months of age, followed by regression with loss of acquired skills, gradual onset of microcephaly, stereotypic hand movements and psychomotor delay.
Rett syndrome (RTT) is an X-linked severe neurodevelopmental disorder mostly affecting female and is mainly caused by mutations of methyl-CpG-binding protein 2 gene (MECP2).
Rett syndrome (RS) is a severe X-linked neurological disorder in which most patients have mutations in the methyl-CpG binding protein2 (MECP2) gene.No effective treatment exists.
Rett Syndrome, an X-linked dominant neurodevelopmental disorder characterized by regression of language and hand use, is primarily caused by mutations in methyl-CpG-binding protein 2 (MECP2).
