The present study aimed to investigate the associations between magnetic resonance (MR) imaging-derived abdominal fat phenotypes (i.e., intra-pancreatic fat deposition (IPFD), intra-hepatic fat deposition (IHFD), skeletal muscle fat deposition (SMFD), visceral fat volume (VFV), subcutaneous fat volume (SFV)) and indices of insulin sensitivity in non-obese individuals with NODAP, T2DM, and healthy controls. The gene discussed is INS; the disease is type 2 diabetes mellitus.
