HLA-DRB1 and cervical cancer: A recent meta-analysis found the class II alleles HLA-DQR*02, -*03, and -*06:03 to decrease and HLA-DQB1*05, -*03:01, and -*04:02 to increase risk of cervical cancer [20], while a genome-wide study concluded HLA-DRB1*06:02 and -*15:01 to be major risk alleles in cervical carcinogenesis [6].
