| Research Abstract |
Defects of the ion channel in retinal cones are related to rod monochromatism(where functional cones are congenitally absent). When the 68 missense mutations(those causing a change in the amino acid sequence) of the channel so far reported were functionally studied, 16 gave membrane current but the others did not. Among the latter, some gave membrane current when the cells were cultured at lower temperature. With regard to such mutations, we are going to establish easier method to have the abnormal channel transported to the cell surface, for practical use.
