Compared with subjects carrying variant genotypes (GG/TG) and non-HPV16 infections, those carrying wild-type genotype (TT) of rs4282438 and HPV16 positive had a 5.22-fold increased risk of cervical cancer (95 % CI = 3.39-8.04).
In this study, associations between invasive cervical cancer and four cervical cancer susceptibility loci (rs13117307 at 4q12, rs8067378 at 17q12, and rs4282438 and rs9277952 at 6p21.32) in the Han Chinese population were investigated in a Japanese population.
No association was found with the two SNPs (rs4282438 or rs9277952) that were recently identified within the HLA-DP region in a cervical cancer GWAS in the Chinese population.
We additionally replicated an association between HLA-DPB1 and HLA-DPB2 (HLA-DPB1/2) at 6p21.32 and cervical cancer (rs4282438, Pcombined, stringently matched=4.52×10(-27), per-allele ORstringently matched=0.75).
