Abstract

To investigate the pathogenic variants of retinal dystrophies in the Japanese population using microarray analysis. DNA extracted from the blood samples of 84 families (87 patients) with retinal dystrophies (retinitis pigmentosa, Leber congenital amaurosis, cone-rod dystrophy and Bietti's crystalline retinopathy) was screened by Asper Biotech services. All the variants detected by microarray analysis were verified by direct sequencing. Mutations were detected in 2 of 36 families with autosomal dominant retinitis pigmentosa, 2 of 4 with Leber congenital amaurosis, 11 of 24 with cone-rod dystrophy, 3 of 7 with macular dystrophy and 6 of 7 with Bietti's crystalline retinopathy. Genotype screening using microarray analysis can be effectively used to determine the variants of retinal dystrophies, except retinitis pigmentosa, in the Japanese population.
