Also known as: D2R; D2DR
Summary: 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. Alternative splicing of this gene results in two transcript variants encoding different isoforms. A third variant has been described, but it has not been determined whether this form is normal or due to aberrant splicing. [provided by RefSeq, Jul 2008]
Annotation information: Note: A frequently studied SNP, known as TaqI DRD2 (rs1800497), was originally associated with the DRD2 gene (GeneID 1813) but was later found to be located within exon 8 of the adjacent gene, ANKK1 (GeneID 255239). The location of rs1800497 is not always specified within publications. Publications may be associated with either locus or with both loci in order to point out the relationship of rs1800497 to both loci. [13 Feb 2013]
Expression: Biased expression in adrenal (RPKM 4.1), endometrium (RPKM 0.7) and 3 other tissues See more

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
