-Relevance to Autism
Case-control and family-based association analysis of the DRD2 gene in a cohort of 112 male-only affected sib-pair ASD families and a comparison cohort of 253 controls revealed an increased frequency of the rs1800498 TT genotype in affected males compared to the comparison group (p=0.007) (Hettinger et al., 2012). Family-based assocation tests in the same report showed that the rs1800498 T allele was over-transmitted to affected males (p=0.0003) under an additive model.
Molecular Function
This gene encodes the D2 subtype of the dopamine receptor. This G-protein coupled receptor inhibits adenylyl cyclase activity. A missense mutation in this gene causes myoclonus dystonia; other mutations have been associated with schizophrenia.

Family-based assocation tests in the same report showed that the rs1800498 T allele was over-transmitted to affected males (p=0.0003) under an additive model. Two SNPs in the DRD2 gene showed suggestive evidence for association with performance on the Peabody Picture Vocabulary Test following meta-analysis of AGRE and SSC cohorts (Eicher and Gruen, 2015).
