| Research Abstract |
Retinitis pigmentosa (RP) is a highly heterogeneous genetic disease including autosomal recessive (ar), autosomal dominant (ad), and X-linked inheritance. This study was conducted to determine the spectrum and frequency of EYS mutations in 100 Japanese arRP patients. We detected 7 very likely pathogenic mutations in 18 patients. Of these 100 patients, 82 were included in the next study after 18 RP patients with very likely pathogenic EYS mutations were excluded. The mutation analysis of the USH2A revealed 5 very likely pathogenic mutations in 4 patients. Based on these data, if both EYS and USH2A genes are analyzed among Japanese arRP patients, gene defects could be detected in 22% of the patients in total (18% and 4%, respectively). We believe that screening for these 2 genes is effective for genetic testing and counseling of RP patients in Japan.
