Analysis of rs25487 (Arg399Gln) in XRCC1 in Sudanese Diagnosed with Nasopharyngeal Carcinoma and Its Possible Risk Factors
Nasopharyngeal carcinoma (NPC) is a multifactorial malignancy influenced by genetic susceptibility and environmental exposures. The XRCC1 Arg399Gln (rs25487) polymorphism has been associated with NPC risk in several populations; however, evidence from African populations remains scarce. This study investigated the asso...
