Modulation of neuritogenesis by a protein implicated in X-linked mental retardation.
Posttranscriptional regulation is an important control mechanism governing gene expression in neurons. We recently demonstrated that VCX-A, a protein implicated in X-linked mental retardation, is an RNA-binding protein that specifically binds the 5' end of capped mRNAs to prevent their decapping and decay. Previously, expression of VCX-A was reported to be testes restricted. Consistent with a r...
متن کاملX-linked mental retardation.
A survey of the mentally retarded children with an IQ between 30 and 55 born in a 10-year period (1955-64) and now of school age was carried out in New South Wales. The number of propositi who had a similarly affected sib of the same sex was ascertained; 58 boys had a similarly affected brother(s) and 22 girls had a similarly affected sister(s). It is suggested that the excess of affected broth...
متن کاملX linked mental retardation: a clinical guide.
Mental retardation is more common in males than females in the population, assumed to be due to mutations on the X chromosome. The prevalence of the 24 genes identified to date is low and less common than expansions in FMR1, which cause Fragile X syndrome. Systematic screening of all other X linked genes in X linked families with mental retardation is currently not feasible in a clinical settin...
متن کاملIdentification of an mRNA-decapping regulator implicated in X-linked mental retardation.
Two major decapping enzymes are involved in the decay of eukaryotic mRNA, Dcp2 and DcpS. Despite the detection of robust DcpS decapping activity in cell extract, minimal to no decapping is detected from human Dcp2 (hDcp2) in extract. We now demonstrate that one reason for the lack of detectable hDcp2 activity in extract is due to the presence of inhibitory trans factor(s). Furthermore, we demon...
متن کاملX-linked mental retardation and epigenetics
The search for the genetic defects in constitutional diseases has so far been restricted to direct methods for the identification of genetic mutations in the patients' genome. Traditional methods such as karyotyping, FISH, mutation screening, positional cloning and CGH, have been complemented with newer methods including array-CGH and PCR-based approaches (MLPA, qPCR). These methods have reveal...
