Furthermore, although there have been reports of human ADIPOR1 single nucleotide polymorphisms (SNPs) associated with diabetes and insulin resistance30–32, there have also been a number of opposing studies finding no such relationship8,33–37, while yet another group failed to validate a previously identified insulin sensitivity-associated SNP but did detect a distinct relationship between this SNP and olfaction38,39. Here, ADIPOR1 is linked to diabetes mellitus.
