Diabetic kidney disease (DKD) is clinically diagnosed in patients exhibiting a reduction in their estimated glomerular filtration rate (eGFR) to <60 ml/min/1.73m2, persistent elevation of albuminuria (Urine Albumin-to-Creatinine Ratio [UACR] ≥ 30 mg/g), or both. This evidence concerns the gene ALB and diabetic kidney disease.
