PCLD has been documented in families from Europe (Netherlands, Belgium, Finland) as well as from the United States. In this article, we report results from extensive mutational analysis of the <jats:italic toggle=\"yes\">PRKCSH<\/jats:italic> gene in a group of 14 PCLD families and 65 singleton cases of Dutch and Finnish descent with multiple simple liver cysts. We identified <jats:italic toggle=\"yes\">PRKCSH<\/jats:italic> mutations in 12 families and in 3 sporadic cases. In 8 of 10 Finnish families we detected the 1437+2delTG splice-site mutation. In Dutch families, we found 2 other mutations that affect correct splicing of <jats:italic toggle=\"yes\">PRKCSH<\/jats:italic>: 292+1 G&gt;C (2 families) and 1338-2 A&gt;G (1 family). In another Dutch family, we detected a novel deletion (374-375delAG) in exon 6, predicting an abnormal shortened protein. Investigation of the carrier haplotypes identified a common founder chromosome in unrelated individuals in each of the 3 identified splice-site mutations. In 2 Finnish families with dominantly inherited PCLD, and in 62 of 65 sporadic cases with multiple simple liver cysts, we failed to demonstrate any <jats:italic toggle=\"yes\">PRKCSH<\/jats:italic> mutation. This corroborates the notion that autosomal dominant PCLD is genetically heterogeneous. In conclusion, we propose that, on the basis of our results, genetic screening for <jats:italic toggle=\"yes\">PRKCSH<\/jats:italic> gene mutations should be limited to patients either with a positive family history for PCLD or who have severe polycystic liver disease.
