The cGAS-STING pathway in innate immunity plays an important role in protecting against HPV infection.Chen et al. described that the rs2516448 SNP in the MHC locus may affect susceptibility to cervical cancer, a finding that we attempted to replicate in a Chinese population.
The C allele of rs9272143 conferred protection against cervical cancer (odds ratio [OR] = 0.73, 95% confidence interval [CI] = 0.65-0.82; P = 1.6 × 10(-7)), which is associated with higher expression level of HLA-DRB1, whereas the T allele of rs2516448 increased the susceptibility to cervical cancer (OR = 1.33, 95% CI = 1.19-1.49; P = 5.8 × 10(-7)), with the same association shown with MICA-A5.1.
