H00480                      Disease                                

Name
X-linked mental retardation
Description
X-linked mental retardation (XLMR) is an inherited condition that causes failure to develop cognitive abilities because of mutations in several genes on the X chromosome. XLMR is subdivided into syndromic and non-syndromic forms (NS-XLMR), depending on whether further abnormalities are found on physical examination, laboratory investigation and brain imaging. The majority of genes that are mutated in NS-XLMR encode proteins are involved in three distinct pathways: Rho GTPases pathway modulating neuronal differentiation and synaptic plasticity; Rab GTPases pathway regulating synaptic vesicle cycling; gene expression regulation.
