“…Variants in different regions of APEX1 gene have been identified and found to influence the susceptibility and progression of different cancers including lung cancer (Lo et al, 2009;Lu et al, 2009), bladder cancer , glioblastoma , cervical cancer , nasopharyngeal carcinoma (Li et al, 2013) and breast cancer (Zang et al, 2006;Kang et al, 2013). Previously 18 single nucleotide polymorphisms (SNPs) in APEX1 have been identified of which, one functional SNPs in promoter region (−656 T>G, rs1760944) and one in the fifth exon (1349 T>G, Glu148Asp, rs1130409) have been widely investigated : Li et al, 2013.…”
