A recent cohort study (TRIBE–AKI Consortium) in adults used urinary biomarkers (tubular injury markers [NGAL, IL-18, KIM-1, L-FABP], tubular function markers [FeNa] and glomerular injury markers [albumin]) to differentiate between various causes of AKI in liver failure. The gene discussed is HAVCR1; the disease is acute kidney injury.
