The T allele in rs3761549 (T/C) FOXP3 was correlated with a susceptibility to lung carcinoma among the Iran population [28], whereas the A allele of rs3761548 significantly increased the NSCLC risk (OR = 2.32 and 95% CI = 1.736–3.102) in Chinese patients [29]. This evidence concerns the gene FOXP3 and non-small cell lung carcinoma.
