Leber congenital amaurosis (LCA) is a genetically and clinically heterogeneous
disease, and represents the most severe form of inherited retinal dystrophy
(IRD). The present study reports the mutation spectra and frequency of known LCA
and IRD-associated genes in 34 Japanese families with LCA (including three
families that were previously reported). A total of 74 LCA- and IRD-associated
genes were analysed via targeted-next generation sequencing (TS), while recently
discovered LCA-associated genes, as well as known variants not able to be
screened using this approach, were evaluated via additional Sanger sequencing,
long-range polymerase chain reaction, and/or copy number variation analyses. The
results of these analyses revealed 30 potential pathogenic variants in 12 (nine
LCA-associated and three other IRD-associated) genes among 19 of the 34 analysed
families. The most frequently mutated genes were CRB1, NMNAT1, and RPGRIP1. The
results also showed the mutation spectra and frequencies identified in the
analysed Japanese population to be distinctly different from those previously
identified for other ethnic backgrounds. Finally, the present study, which is the
first to conduct a NGS-based molecular diagnosis of a large Japanese LCA cohort,
achieved a detection rate of approximately 56%, indicating that TS is a valuable
method for molecular diagnosis of LCA cases in the Japanese population.
