The Hardy–Weinberg equilibrium analysis indicated a deviation from the equilibrium in the case of rs2279017 (XPC) at p = 4.48E−04 and rs11615 (ERCC1) p = 4.78E−02, only in the group of CRC affected individuals collected and genotyped at WMU (Supplementary Table 4 in comparison with Supplementary Table 5 and Table 6). This evidence concerns the gene XPC and colorectal carcinoma.
