Genes affected
DLG3 (HGNC:2902): (discs large MAGUK scaffold protein 3) 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 cognitive disability. Alternatively spliced transcript variants have been described. [provided by RefSeq, Oct 2009]
DLG3-AS1 (HGNC:40182): (DLG3 antisense RNA 1)
