Renal damage markers, particularly those associated with tubular dysfunction such as neutrophil gelatinase-associated lipocalin (NGAL), N-acetyl-β-D-glucosaminidase (NAG), and kidney injury molecule (KIM-1), have recently attracted attention as sensitive and specific biomarkers to detect early kidney damage [5, 6]. The gene discussed is LCN2; the disease is Nephropathy.
