BRCA2 and colorectal carcinoma: Moreover, the correlation analysis between ethnic-related BRCA2 SNPs and BRCA2 PVs in the CRC patients’ blood revealed that there were positive correlations between c.7397 T > C SNP and c.3860delA PV (r = 0.3, P < 0.05), as well as c.1114A > C SNP with c.4169delT and c.7177delA PVs (r = 0.5, P < 0.05; r = 0.3, P < 0.05, respectively).
