Autosomal dominant tubulointerstitial kidney disease-2 (ADTKD2) is characterized by adult onset of impaired renal function and salt wasting resulting in chronic renal insufficiency and end-stage renal failure by the sixth decade. Renal biopsy shows tubulointerstitial nephropathy, sometimes with the formation of renal cysts at the corticomedullary junction, although cysts are not pathognomonic for the disease and are not an essential criterion for the diagnosis. More variable features may include anemia, hypertension, hyperuricemia, and gout; urinary sediment is bland. The features are nonspecific and there is significant inter- and intrafamilial variability, as well as incomplete penetrance, which may hinder the clinical diagnosis (summary by Stavrou et al., 2002, Wolf et al., 2004; review by Devuyst et al., 2019).
