TNFRSF1A and type 2 diabetes mellitus: Compared to the Joslin Study of the Genetics of Type 2 Diabetes and Kidney Complications, the SURDIAGENE study had a much higher incidence of mortality (Table 2), which might be attributed in part to clinical characteristics (SURDIAGENE patients were older and had lower eGFR compared to Joslin patients), although the impact of circulating TNFR1 levels on ESRD was extremely similar with both studies.
