Outline of Final Research Achievements

Leber congenital amaurosis (LCA) is a genetically heterogeneous disease, whose clinical features include blindness or severe visual impairment within the first year of life and represents the most severe form of inherited retinal dystrophy (IRD). We performed the mutation analysis in 34 Japanese families with LCA to evaluate the mutation spectrum and frequency of known LCA-associated genes in the Japanese population. 74 genes responsible for IRD were examined by targeted-next generation sequencing (NGS).
The results of these analyses revealed 30 potential pathogenic variants in 12 genes among 19 of the 34 analyzed families. The results also showed the mutation spectra and frequencies identified in the analyzed Japanese population to be distinctly different from those previously identified for other ethnic backgrounds. The observed detection rate of about 56% indicated that targeted NGS is a valuable method for molecular diagnosis of LCA cases in the Japanese population.

Academic Significance and Societal Importance of the Research Achievements

Leber先天盲(LCA)は、生後早期より高度に視機能が障害される遺伝性網膜疾患である。LCAの原因遺伝子の同定は、予後の判定に重要である。2017年末にアメリカ食品医薬品局がLCAの原因遺伝子RPE65の遺伝子治療を承認し、患児らに希望を与える事になった。この遺伝子治療を受けるには原因遺伝子の特定が必須であり、遺伝子診断の重要性は増している。本研究では、日本人LCA 34家系の遺伝子診断を行い19家系の患児から原因変異の可能性が高い変異を検出した。今回検討した家系からはRPE65遺伝子治療に適応する患児は検出されなかったが、本研究の成果はわが国の今後の遺伝子治療を考える上で必要な情報である。
