For associations at cg20812370 (PBX1) and cg01577083 (RBFOX1), there was little evidence of heterogeneity in the effect of 62 type 2 diabetes SNPs on DNAm levels based on the results of the Cochran’s Q test (Q range 52.9–74.8, p value range 0.10–0.75). This evidence concerns the gene RBFOX1 and type 2 diabetes mellitus.
