{"symbol":"SLC6A3","synonyms":["DAT","PKDYS","PKDYS1","DAT1"],"name":"solute carrier family 6 (neurotransmitter transporter), member 3","description":"This gene encodes a dopamine transporter which is a member of the sodium- and chloride-dependent neurotransmitter transporter family. The 3\u0027 UTR of this gene contains a 40 bp tandem repeat, referred to as a variable number tandem repeat or VNTR, which can be present in 3 to 11 copies. Variation in the number of repeats is associated with idiopathic epilepsy, attention-deficit hyperactivity disorder, dependence on alcohol and cocaine, susceptibility to Parkinson disease and protection against nicotine dependence.[provided by RefSeq, Nov 2009]","ncbiEntrezGeneId":6531,"ncbiEntrezGeneUrl":"http://www.ncbi.nlm.nih.gov/gene/6531","proteins":[{"symbol":"SC6A3_HUMAN","href":"/api/1.0/protein/SC6A3_HUMAN"}],"hgncRootFamilies":[{"name":"Solute carriers (SLC)","href":"/api/1.0/gene_family/Solute+carriers+%28SLC%29"}]}
