Genes affected

DRD1 (HGNC:3020): (dopamine receptor D1) This gene encodes the D1 subtype of the dopamine receptor. The D1 subtype is the most abundant dopamine receptor in the central nervous system. This G-protein coupled receptor stimulates adenylyl cyclase and activates cyclic AMP-dependent protein kinases. D1 receptors regulate neuronal growth and development, mediate some behavioral responses, and modulate dopamine receptor D2-mediated events. Alternate transcription initiation sites result in two transcript variants of this gene. [provided by RefSeq, Jul 2008]

The c.1336A>G (p.T446A) alteration is located in exon 2 (coding exon 1) of the DRD1 gene. This alteration results from a A to G substitution at nucleotide position 1336, causing the threonine (T) at amino acid position 446 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
