ERAP1 and cervical squamous intraepithelial neoplasia: Thus, in the current study, we selected 11 SNPs located in ERAP1 (rs27037, rs27044, rs30187, rs26618, rs26653 and rs3734016) and ERAP2 (rs2549782, rs2548538, rs2248374, 2,287,988 and rs1056893) and investigated their distribution in patients with cervical intraepithelial neoplasia (CIN) and cervical cancer and healthy individuals, to assess their association with the initiation and development of cervical cancer.
