Interestingly, the serum PSAP (319.6 ± 78.38 vs. 207.2 ± 42.43, P<0.0001) and EPDR1 (7.988 ± 3.484 vs. 6.399 ± 3.788, P=0.0823) concentrations were significantly higher in T2DM subjects compared to normal control controls (see Figure 2). This evidence concerns the gene PSAP and type 2 diabetes mellitus.
