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]

Collection Method: clinical testing

The c.50A>T (p.E17V) alteration is located in exon 2 (coding exon 1) of the DRD1 gene. This alteration results from a A to T substitution at nucleotide position 50, causing the glutamic acid (E) at amino acid position 17 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
