HLA-DPA1 and cervical cancer: In addition, HLA-DP rs9277535 G allele and DPB1∗13:01 might be regarded as protective factor (95%CI: 0.753-0.855, Pz=0.001) and risk factor (95%CI: 1.107-3.039, Pz=0.019) of cervical cancer in Asia, respectively, while HLA-DPB1∗13:01 was not regarded as risk factor for cervical cancer in the GWAS of cervical cancer in Japanese [7]; that might be related to the relatively small number of cases of the GWAS, thus having low weight.
