GMPS and diabetes mellitus: Comparison of skeletal muscle gene expression profiles 1-year post-surgery resulted in only three significant probes that mapped to three genes: ring finger protein 6 (RNF6; p = 0.003, FC = 1.8 greater in individuals with diabetes vs. without), coiled-coil domain containing 90A (CCDC90A; p = 0.007, FC = 1.3), and guanine monophosphate synthetase (GMPS; p = 0.002, FC = −1.3).
