SERPINA12 and type 2 diabetes mellitus: Indeed, we demonstrated that a significant subpopulation (7%) of both the subjects with normal fasting glucose levels (n = 259) and patients with type 2 diabetes (n = 275) displayed much higher levels (10-40 ng/ml; VaspinHigh group), while the serum vaspin levels of 93% of the samples varied from 0.2 to 3 ng/ml in the VaspinLow group.
