FLCN and diabetic retinopathy: (b) Bar plot comparing the true positive rate (π1), TPR, for association of diabetic retinopathy with all SNPs, all eSNPs, eSNPs from the 103 differential response genes to glucose (n = 7253), and eSNPs found in retina and >20 GTEx tissues for folliculin (FLCN) (n = 272).
