| Outline of Final Research Achievements |
Autosomal dominant polycystic kidney disease (ADPKD) is the genetic disorder most commonly associated with increased risk of intracranial aneurysms (IA), and caused by deleterious mutations in PKD1 and PKD2. In this study, we tested whether IAs without obvious renal diseases also share a part of genetic backgrounds with ADPKD. We performed next generation sequencing of PKD1 and PKD2 in familial IA patients without ADPKD. Putatively functional variants were identified more frequently in the IA patients than in non-IA controls. Especially, the difference in extracellular region of PKD1 was more evident. This is the first report that PKD1 and PKD2 may be susceptibility genes of IA even in patients without ADPKD.
