Saulnier et al. [51] examined the association between circulating TNFR1 levels and all-cause mortality in 522 patients with type 2 diabetes and DKD (eGFR < 60 mL/min/1.73 m2 and/or albumin/creatinine 30 mg/mmol) using a follow-up study of Survie, Diabete de type 2 et Genetique (SURDIAGENE). This evidence concerns the gene TNFRSF1A and diabetic kidney disease.
