| Outline of Final Research Achievements |
KO mice lacking the Kansl1-L gene associated with hyperparathyroidism were male infertile, became polycystic kidney with age. We investigated how Kansl1-L is involved in cystic kidney formation. Dilation of the tubules, source of cysts, was observed in both males and females from the age of 2 weeks old. The number of dilated tubules increased with aging, but only in males, multiple cysts and enlargement were seen. Polycystic kidney disease occurred in about half of KO males. Kansl1-L was shown to be a causative gene of a pathway different from Pkd1 and Pkd2, suggesting a relationship with cilia.

| Academic Significance and Societal Importance of the Research Achievements |
Kansl1-L欠損多発性嚢胞腎は老齢になって初めて発症すると思われたが、嚢胞のきっかけである尿細管の拡張は生後2週齢からみられた。さらに老年60週齢ころの嚢胞の大型化と多発は雄だけにみられ、この嚢胞腎は雌雄差のある疾患であることがわかった。Kansl1-Lは今までにみつかっていない、発症に性差がある多発性嚢胞腎の原因遺伝子であり、雄性不妊を合併する遺伝性疾患の原因遺伝子の可能性がある。
