Autosomal recessive polycystic kidney disease (ARPKD) is a hereditary disorder with an incidence of 1/10 000 to 1/40 000 individuals [1,2]. ARPKD is caused by mutations in the PKHD1 gene on chromosome 6p12 [3,4]. Prenatally, oligohydramnion, enlarged kidneys and lung hypoplasia with the typical Potter facies become evident. Principal histological manifestations involve the fusiform dilation of renal collecting ducts and distal tubuli as well as dysgenesis of the hepatic portal triad (so-called ductal plate malformation with congenital hepatic fibrosis and hyperplastic biliary ducts). The spectrum of the disease is highly variable ranging from severe perinatal manifestations to later onset and milder forms. Severe phenotypes are more often associated with truncating PKHD1 changes than moderately affected individuals [5,6]. Especially children with severe renal disease show a high perinatal mortality. Death is often caused by respiratory insufficiency due to lung hypoplasia and displacement of the diaphragm by bilateral
