Mutations of the nephrocystin 3 gene cause autosomal recessive adolescent Nephronophthisis or Renal-hepatic-pancreatic dysplasia (RHPD).
Gene mutations cause alteration of tubular basement membrane, degeneration and dilatation of tubules, which finally leads to generalized tubulo-interstitial sclerosis. Cysts predominantly appear at the cortico-medullary junction.
