Genes affected

DLGAP1 (HGNC:2905): (DLG associated protein 1) Predicted to enable molecular adaptor activity. Predicted to be a structural constituent of postsynaptic density. Predicted to be involved in several processes, including aggresome assembly; regulation of postsynaptic neurotransmitter receptor activity; and regulation of proteasomal protein catabolic process. Predicted to be located in plasma membrane. Predicted to be part of postsynaptic density. Predicted to be active in glutamatergic synapse and postsynaptic density, intracellular component.
