The molecular basis of variable phenotypic severity among common missense mutations causing Rett syndrome
Rett syndrome is caused by mutations in the X-linked MECP2 gene, which encodes a chromosomal protein that binds to methylated DNA. Mouse models mirror the human disorder and therefore allow investigation of phenotypes at a molecular level. We describe an Mecp2 allelic series representing the three most common missense Rett syndrome (RTT) mutations, including first reports of Mecp2[R133C] and Me...
متن کاملIdentification of a Novel Arylsulfatase B Gene Mutation in Three Unrelated Iranian Mucopolysaccharidosis Type-VI Patients with Different Phenotype Severity
Background: Mucopolysaccharidosis type-VI (MPS-VI), which is inherited as an autosomal recessive trait, results from the deficiency of N-acetylgalactosamine 4-sulfatase (arylsulfatase B) activity and the lysosomal accumulation of dermatan sulfate. In this study, ARSB mutation analysis was performed on three unrelated patients who were originally from the West Azerbaijan province of Iran. Method...
متن کاملMutational analysis of MECP2 in Japanese patients with atypical Rett syndrome.
Rett syndrome (RTT) is one of the most common neurodevelopmental disorders in females. Recently, this disease was found to be linked with mutations in the methyl-CpG-binding protein 2 gene (MECP2) and various mutations have been reported. To explore the spectrum of phenotypes resulting from MECP2 mutations, we searched for mutations in the MECP2 of 20 Japanese patients who had more than five of...
متن کاملMicroduplication of Xp22.31 and MECP2 Pathogenic Variant in a Girl with Rett Syndrome: A Case Report
Rett syndrome (RS) is a neurodevelopmental infantile disease characterized by an early normal psychomotor development followed by a regression in the acquisition of normal developmental stages. In the majority of cases, it leads to a sporadic mutation in the MECP2 gene, which is located on the X chromosome. However, this syndrome has also been associated with microdeletions, gene translocations...
متن کاملRett syndrome with and without detected MECP2 mutations: an attempt to redefine phenotypes.
BACKGROUND The diagnosis of Rett syndrome (RTT) is based on a set of clinical criteria, irrespective of mutation status. The aims of this study were (1) to define the clinical differences existing between patients with Rett syndrome with (Group I) and without a MECP2 mutation (Group II), and (2) to characterize the phenotypes associated with the more common MECP2 mutations. PATIENTS AND METHO...
