Summaries for Mental Retardation, X-Linked 102

UniProtKB/Swiss-Prot : 75 Mental retardation, X-linked 102: A form of mental retardation, a disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Intellectual deficiency is the only primary symptom of non-syndromic X-linked mental retardation, while syndromic mental retardation presents with associated physical, neurological and/or psychiatric manifestations. MRX102 features include mild to severe intellectual disability, hypotonia, movement disorders, behavior problems, corpus callosum hypoplasia, and epilepsy. Additionally, patients manifest variable non-neurologic features such as joint hyperlaxity, skin pigmentary abnormalities, cleft lip and/or palate, hearing and visual impairment, and precocious puberty.

MalaCards based summary : Mental Retardation, X-Linked 102, also known as mrx102, is related to lung cancer. An important gene associated with Mental Retardation, X-Linked 102 is DDX3X (DEAD-Box Helicase 3 X-Linked). Affiliated tissues include skin and lung, and related phenotypes are precocious puberty and intellectual disability
