-Relevance to Autism
Deletion of DLGAP3 in mice results in increased anxiety and compulsive grooming behavior, which can be alleviated by a selective serotonin reuptake inhibitor, as well as defects in cortico-striatal synapses (Welch et al., 2007). Rare and common variants in the DLGAP3 have subsequently been shown to associate with obsessive-compulsive disorder (OCD) , Tourette Syndrome (TS), and pathological grooming behaviors in humans (Bienvenu et al., 2008; Zuchner et al., 2009; Crane et al., 2011).
Molecular Function
May play a role in the molecular organization of synapses and neuronal cell signaling. Could be an adapter protein linking ion channel to the subsynaptic cytoskeleton. May induce enrichment of PSD-95/SAP90 at the plasma membrane.

SFARI Gene score
Strong Candidate


The protein encoded by the DLGAP3 gene interacts with the proteins encoded by the high confidence ASD genes SHANK2, SHANK3, and CUL3 (Boeckers et al., 1999; Bennett et al., 2010). Deletion of DLGAP3 in mice results in increased anxiety and compulsive grooming behavior, which can be alleviated by a selective serotonin reuptake inhibitor, as well as defects in cortico-striatal synapses (Welch et al., 2007). Rare and common variants in the DLGAP3 have subsequently been shown to associate with obsessive-compulsive disorder (OCD), Tourette Syndrome (TS), and pathological grooming behaviors in humans (Bienvenu et al., 2008; Zuchner et al., 2009; Crane et al., 2011; Boardman et al., 2011).
