Abstract

Key Clinical Message: We report an otherwise healthy 32‐year‐old man with portal hypertension, variceal bleeding, and congenital hepatic fibrosis with ductal plate malformation. Genetic screening identified two TMEM67 mutations. Biallelic TMEM67 mutations are known to cause Joubert/Meckel syndrome or nephronopthisis with hepatic fibrosis, but have never been found in isolated hepatic fibrosis.
