It was interesting that rs12444338, rs4738244 and rs12051272 SNPs, which are in different regions of CDH13 gene showed a correlation trend with NSCLC (P = 0.011, 0.018 and 0.024, respectively), which might be due to the fact that rs12444338 was in LD with the rs4783244 and rs12051272 (Table 4). Here, CDH13 is linked to non-small cell lung carcinoma.
