We report a large three-generation autosomal dominant polycystic kidney disease family from Northern Italy found to be associated with the PKD2 locus. Hepatic involvement (liver cysts, fibrosis, cholelithiasis or jaundice), subarachnoidal hemorrhage (1 case) and esophageal diverticula (1 case) were present in affected individuals. Among the older members, the males (aged 54-61 years) had hepatic cysts or fibrosis and were on chronic hemodialysis, the females (aged 69 and 70 years) had hepatic cysts, hepatomegaly, mild fibrosis and a mild and moderate renal impairment, respectively. In this family, clinical findings do not differ substantially from those reported for PKD1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
