| Outline of Final Research Achievements |
We have found novel retinal degeneration disease in mountainous area of Miyazaki prefecture. Firstly, we have investigated of familial history with the novel disease, as a result, we detected two big pedigrees. Secondly, we have examined to various ophthalmologic examinations. As a result, features of the novel disease were late onset, and macular and peripheral retina degeneration with deposit. In the last, we have tried to detect of cause gene. We have examined to four gene, those gene have similar phenotype to the novel disease. As a consequence, we could not detect cause gene. For that reasen, we have examined hole exome sequencing, as a result, we have detected cause gene.

| Academic Significance and Societal Importance of the Research Achievements |
本疾患の特徴である網膜下沈着物は、他の疾患においても遭遇する所見である。網膜下沈着物の発生機序は明らかにされていない。本研究で明らかとなった、新規遺伝子の機能解析を進めることで、網膜下沈着物の発生機序および、網膜変性疾患の機序解明の一助となる可能性が示唆される。また、本疾患は、一部の患者において脈絡膜新生血管を伴う症例があることや、網膜下沈着物を伴うことから、加齢黄斑変性として診断・治療されている場合が存在する。本疾患が明らかになることで、適切な診断、さらには治療に繋がる可能性が示唆される。
