ARAP1 and type 2 diabetes mellitus: Recent expression quantitative trait loci (eQTL) studies in normoglycemic donors30 have suggested that islet STARD10 expression is correlated with T2D risk variants at this locus, whereas no such islet eQTL association was observed for ARAP1. These findings contrast with other results31 reporting higher ARAP1 mRNA synthesis from the T2D risk allele.
