| Research Abstract |
Thirty dichromats had a genotype of anomalous trichromacy, and 85 color-deficient subjects had a normal genotype; a total of 115 among the 725 subjects showed a discrepancy between their phenotype and genotype. Among them, 82 subjects had a base substitution of －71A→C, which is thought to cause no or little expression of the corresponding visual pigment gene. Eleven subjects had a mutation in the exons. Two had a unique haplotype in exon 3, which causes complete skipping of the exon at splicing.
