The solute carrier family 1 (glial high affinity glutamate transporter), member 2 gene, SLC1A2, rs3794087 variant and assessment risk for restless legs syndrome
2014
Abstract Objective A glutamatergic dysfunction has been postulated to play a role in restless legs syndrome (RLS) pathophysiology, as glutamate concentrations have been found to increase in the thalamus of RLS patients. The aim of our study was to investigate the possible association between the single nucleotide polymorphism (SNP) rs3794087 in the solute carrier family 1 (glial high affinity glutamate transporter), member 2 gene, SLC1A2 , related with glutamate transport and the risk for RLS. Methods We studied the allelic and genotype frequencies of the SNP rs3794087 in 205 patients with RLS and 328 healthy controls using TaqMan genotyping. Results The rs3794087 genotype and allelic frequencies did not significantly differ between patients with RLS and controls and were unrelated with the age at onset of RLS, gender, and family history of RLS. Conclusions The results of our study suggest that the rs3794087 polymorphism is not related to the risk for RLS.
