PPARG and type 2 diabetes mellitus: Among them, rs2920502 and linked SNPs like rs2920500 could be particularly interesting because PPARG has been associated with the development of type 2 diabetes, atherosclerosis, and cancer [7], [58], and because PPAR-γ agonists (e.g., thiazolidinedione) have been used to treat type 2 diabetes [58].
