Higher CRP concentrations were also observed in the diabetic nephropathy group with the 4b/4b genotype (p = 0.028) and in the kidney transplant diabetic nephropathy group with the 4a/4b genotype (p = 0.002) and the 4b/4b genotype (p = 0.014) compared to the control groups with the same genotypes. The gene discussed is CRP; the disease is diabetic kidney disease.
