HLA-C and cervical carcinoma: Moreover, their expression levels are only weakly correlated with each other; for example, the Pearson's correlation coefficient of expression levels for all pairs of the four genes ranges from -0.123 (between RP11.384K6.6 and ITSN1) to 0.304 (between RP11.384K6.6 and RP11.384K6.2) in terms of 376 EUR individuals in the Geuvadis Project 19, implying that the four non-MHC genes are likely new novel genes involved in the risk of developing cervical cancer.
