Genes affected

SLC6A3 (HGNC:11049): (solute carrier family 6 member 3) This gene encodes a dopamine transporter which is a member of the sodium- and chloride-dependent neurotransmitter transporter family. The 3' 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]

Experimental studies have shown that this missense change leads to altered protein function and localization in cell culture experiments (PMID: 22514303, 25747272). In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has been reported in individuals affected with attention-deficit hyperactivity disorder (ADHD).¬†This variant is also described as 2026T/C in the literature. In the same study the authors incorrectly refer to this variant in the SLC6A4 gene, while later describing it correctly as being present in the SLC6A3 gene (PMID: 22514303). This sequence change replaces arginine with cysteine at codon 615 of the SLC6A3 protein (p.Arg615Cys). The arginine residue is moderately conserved and there is a large physicochemical difference between arginine and cysteine. This variant is present in population databases at a very low frequency (rs763131939, ExAC <0.01%). -
