| Outline of Final Research Achievements |
We established disease-specific iPS cells from retinitis pigmentosa patients with homozygous EYS c.8805C>A mutations. These cells will be available through Riken BioResource Center after a certain period. Two-dimentional retina-like cell culture was established from these iPS cells. Candidate drugs are screened for their potential to modulate expression of EYS mRNA and protein. In addition, while we reviewed genotype-phenotype correlations in patients with retinitis pigmentosa, we found that environmental factors such as tobacco smoking may affect clinical course.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、網膜色素変性の原因として本邦で特に頻度の高い変異をもつiPS細胞を樹立した。本細胞株は理研BRCに寄託しており、他の研究者も自由に使用することが出来るため更なる発展につながる可能性がある。また本研究で得られた環境因子（喫煙）による病態の修飾という知見については、直ちに臨床に還元することも可能なものであり、確立した治療法のない本疾患にとって重要なものになると考えらえる。
