SYNM and type 2 diabetes mellitus: Using data from the Genetics of DNAm consortium (GoDMC) [29], we found six methylation quantitative trait loci (meQTL) in blood (five in cis and one in trans) associated with five of our six T2D-associated CpGs in cg19693031 (TXNIP), cg06500161 (ABCG1), cg00144180 (HDAC4) (n = 2 meQTL), cg16765088 (SYNM) and cg24704287 (MIR23A) (Additional file 1: Table S16).
