SLC31A1 and non-small cell lung carcinoma: In the NSCLC patient cohort, we genotyped eight tagging and potentially functional SNPs of SLC31A1 gene, three at 5′flanking region (rs4979223, rs4978536 and rs2233914), three at the intron (rs10817464, rs10981699 and rs10817465), and two at 3′UTR (rs10513202 and rs10759637), all of which were in Hardy-Weinberg equilibrium (HWE) (Supplementary Table 1), and six of which are common variants (minor allele frequency, MAF >0.05) in this study population.
