TP53 and nasopharyngeal carcinoma: Our analysis indicates that miR-146a (rs2910164, C>G), HCG9 (rs3869062, A>G), HCG9 (rs16896923, T>C), MMP2 (rs243865, C>T), GABBR1 (rs2076483, T>C), and TP53 (rs1042522, C>G) are associated with decreased susceptibility to NPC, while the other SNPs might contribute instead to increased risk of NPC.
