The GA + AA and GG genotypes in our study are equivalent to the CT + TT and CC genotypes, respectively, described in the studies referenced in this paragraph since they refer to the genotypes on the minus (antisense) strand [6,19,24,25,32] Previous analyses of visfatin SNP rs61330082 have reported that it is associated with an increased risk of NSCLC, esophageal squamous cell cancer (ESCC), bladder cancer, and HCC [6,19,24,25,32]. Here, NAMPT is linked to esophageal squamous cell carcinoma.
