| Outline of Final Research Achievements |
Retinitis pigmentosa (RP) is a highly heterogeneous genetic disease with autosomal recessive (ar), autosomal dominant, or X-linked inheritance. We analyzed mutations of EYS and USH2A in Japanese arRP cases (total 100). The analysis of EYS for 100 RP patients elucidated 7 probable pathogenic mutations from 18 cases.
Our recent analysis of the EYS using MLPA method to assay the copy number of each exon elucidated a case with an exon deletion and another case with an exon duplication from 9 patients in which only one probable causative mutation had been detected. It is quite possible that more of copy number mutations latently exist in EYS and others of RP patients.
