Genes affected

DRD3 (HGNC:3024): (dopamine receptor D3) This gene encodes the D3 subtype of the five (D1-D5) dopamine receptors. The activity of the D3 subtype receptor is mediated by G proteins which inhibit adenylyl cyclase. This receptor is localized to the limbic areas of the brain, which are associated with cognitive, emotional, and endocrine functions. Genetic variation in this gene may be associated with susceptibility to hereditary essential tremor 1. Alternative splicing of this gene results in transcript variants encoding different isoforms, although some variants may be subject to nonsense-mediated decay (NMD). [provided by RefSeq, Jul 2008]

The c.1018G>T (p.V340F) alteration is located in exon 7 (coding exon 6) of the DRD3 gene. This alteration results from a G to T substitution at nucleotide position 1018, causing the valine (V) at amino acid position 340 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
