SLC2A1 and diabetes mellitus: In all European Americans, multivariate analysis adjusting for diabetes simultaneously examined the association with albuminuria of all six GLUT1 SNPs, and the Enh2 risk genotype had an increased OR with albuminuria (OR = 3.37, 95% CI: 0.83 - 13.78, p = 0.090) whereas XbaI did not (OR = 0.94, 95% CI: 0.26-3.42, p = 0.931).
