The Role of Mutations on Genes OPN1LW, OPN1MW, OPN1SW in Color Vision Deficiency Syndrome |Biomedgrid

Color vision deficiency syndrome, sometimes known as color blindness, is a genetic disorder that affects color perception. Red-green eyesight is the most common form of this syndrome. Affected people have a hard time recognizing some shades of red, yellow and green. Blue-yellow (also called Tritan defects), which rarely occurs, causes difficulty distinguishing between blue and green shades and makes it difficult to distinguish dark blue from black. The most severe and less common type of color vision deficiency syndrome is the blue monochrome cone, which causes severe visual acuity and severe reduction in color vision. Color vision deficiency syndrome is caused by mutations in the OPN1LW gene and the OPN1MW gene, which are located on the long arm of the sex X chromosome as Xq28, and the OPN1SW gene, which is located on the long arm of chromosome 7 as 7q32.1.
