Trait	Controls	T2DM
Gender (Male/Female)	95/93	192/172

Available demographic characteristics of case control population. See also Materials and Methods. Individuals with nephropathy had either microalbumin:creatinine ratios over 300, end stage renal disease, or elevated creatinines without another cause. Individuals without nephropathy had 10 years of T2DM with a microalbumin:creatinine ratio under 30. All other individuals, including those with microalbuminuria, were considered unknown. * Significantly different at p < 0.001.
