T-Cell Cytokine Gene Polymorphisms and Vitamin D Pathway Gene Polymorphisms in End-Stage Renal Disease due to Type 2 Diabetes Mellitus Nephropathy: Comparisons with Health Status and Other Main Causes of End-Stage Renal Disease
Table 5
Comparison of the distribution of polymorphic variants of tested genes between ESRD patients treated with hemodialysis due to type 2 DM nephropathy and the most common causes of ESRD other than type 2 DM nephropathy (chronic glomerulonephritis, chronic tubulointerstitial nephritis, and hypertensive nephritis).
