Several SNPs are associated with genes that play a key role in T2D and, according to the GTEx RNA-seq track of the UCSC Genome Browser, have the highest median expression in the liver; this is the case of NAT2 (rs1495741), FURIN (rs2521501), and SLC30A1 (rs2157719). This evidence concerns the gene SLC30A1 and type 2 diabetes mellitus.
