We finally screened out 13 eQTL-SNPs localized in Co-m6ARs, and 4 have been reported strongly associated with diabetes, including GAB2, LMNB2, XAB2, and RBM39. This co-expression analysis provides important information to reveal the potential regulatory mechanism of RNA m6A methylation in T2DM. Here, RBM39 is linked to diabetes mellitus.
