DRD2 - dopamine receptor D2 Gene
Also Known as D2R; D2DR
Species: Homo sapiens
About DRD2
This gene has 10 transcripts (splice variants), 207 orthologues, 18 paralogues and is associated with 1 phenotype. Biased expression in adrenal (RPKM 4.1), endometrium (RPKM 0.7) and 3 other tissues.
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]
