Entrez Gene Summary for DLG3 Gene

  • This gene encodes a member of the membrane-associated guanylate kinase protein family. The encoded protein may play a role in clustering of NMDA receptors at excitatory synapses. It may also negatively regulate cell proliferation through interaction with the C-terminal region of the adenomatosis polyposis coli tumor suppressor protein. Mutations in this gene have been associated with X-linked mental retardation. Alternatively spliced transcript variants have been described. [provided by RefSeq, Oct 2009]

GeneCards Summary for DLG3 Gene

DLG3 (Discs, Large Homolog 3 (Drosophila)) is a Protein Coding gene. Diseases associated with DLG3 include non-syndromic x-linked intellectual disability and partington syndrome. Among its related pathways are L1CAM interactions and L1CAM interactions. GO annotations related to this gene include protein C-terminus binding and PDZ domain binding. An important paralog of this gene is MPP6.

  • Mental retardation, X-linked 90 (MRX90) [MIM:300850]: 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. {ECO:0000269 PubMed:15185169}.
