XRCC5 and colorectal carcinoma: The same research group also identified significant association of overall survival in CRC with SNPs located in miRNA target sites of DNA repair protein RAD52 homolog (RAD52) (rs11226), X-ray repair cross-complementing protein 5 (XRCC5) (rs1051685) and single-strand-selective monofunctional uracil-DNA glycosylase 1 (SMUG1) (rs2233921) [140,141].
