HLA-DPB1 and cervical cancer: Consistent with these observations, in a meta-analysis of 11 studies including 5008 cases and 9322 controls, the variants HLA-DPB1⁎03:01, DPB1⁎04:02, DPB1⁎13:01, rs9277535 and rs3117027 in the HLA-DP gene were significantly associated with cervical cancer [46], thus substantiating the associations between genetic variations in the HLA locus and susceptibility to cervical cancer.
