GSTO1 as a Potential Risk Factor for Diabetic Nephropathy: Evidence From Mendelian Randomisation and Multi‐Omics Analyses

Diabetic nephropathy (DN) is a major complication of diabetes mellitus and a leading cause of end‐stage renal disease (ESRD). Glutathione S‐transferase omega 1 (GSTO1) is implicated in redox regulation and inflammation, but its causal role in DN remains unclear. This study aimed to investigate the potential causal relationship between GSTO1 and DN risk.
