The correlation coefficients between ERBB3 methylation and the abundance of MHC in cervical cancer are arranged as follows: HLA-E r = 0.514 (p < 0.01), HLA-DQA2 r = 0.471 (p < 0.01), TAP1 r = 0.471 (p < 0.01), HLA-DPB1 r = 0.464 (p < 0.01), HLA-DRA r = 0.455 (p < 0.01), HLA-DPA1 r = 0.454 (p < 0.01). Here, HLA-DRA is linked to cervical carcinoma.
