Summaries for Mental Retardation, X-Linked, Syndromic, Wu Type

UniProtKB/Swiss-Prot : 75 Mental retardation, X-linked 94: 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. MRX94 patients have moderate mental retardation. Other variable features are macrocephaly, seizures, myoclonic jerks, autistic behavior, asthenic body habitus, distal muscle weakness and hyporeflexia.

MalaCards based summary : Mental Retardation, X-Linked, Syndromic, Wu Type, is also known as mrx94, and has symptoms including seizures and myoclonus. An important gene associated with Mental Retardation, X-Linked, Syndromic, Wu Type is GRIA3 (Glutamate Ionotropic Receptor AMPA Type Subunit 3). Affiliated tissues include eye and bone, and related phenotypes are macrocephaly and intellectual disability

Disease Ontology : 12 A syndromic X-linked intellectual disability characterized by moderate intellectual disability with variable occurrence of asthenic body habitus, dysmorphic features, autistic features, macrocephaly, seizures, myoclonic jerks, and hyporeflexia that has material basis in mutation in the GRIA3 gene on chromosome Xq25.
