ERCC1 and nasopharyngeal carcinoma: The genotype frequency of SNP rs2274084 on GJB2 gene was significantly different between EBV‐positive NPC and normal control.26 The C118T genotype on the excision repair cross‐complementing group 1 (ERCC1) gene was reported to be associated with plasma EBV DNA levels.27 In the present study, we found that rs11169571 on ATF1 was associated with the risk of NPC.
