| Research Abstract |
Pigmentpharbenanomaly, a kind of the congenital red-green color blindness which indicates color muching by anomaloscope. We investigated the sequences of all exons of the red and green pigment genes of two pigmentpharbenanomalies. Because of the sequences were all-same as that of normal color vision, It was thought that the mechanism of Pigmentpharbenanomaly is not the abnormality of the opsins in cones.
We succeeded in the genetic analyze of male congenital color vision defects by quantitative PCRSSCP.But in female color vision defects, two X-chromosomes made the analyze is impossible.
In the analyze of the female carrier of color vision defect, we succeeded in the detection of the color vision defect gene in only protanomalous carrier but not in deuteranomalous carrier.
The mRNAs of opsin genes are in White Blood Cells (WBC) is well known. We tried to compare the mRNAs in WBC with the phenotype-color vision. Very little amount of mRNA in WBC made the analyze difficult.
