Cure for rare form of color blindness steps closer with novel gene insight. In a new study published in PLOS ONE, researchers have uncovered novel insights into two genetic mutations that may be a cause of a rare form of color blindness called achromatopsia, paving the way for a cure for the condition.
Ninety-nine percent of people with color blindness have difficulty distinguishing between red and green. The absence of one pigment will cause red-green colorblindness. The absence of two pigments will make it difficult to distinguish between blue and yellow as well as green and red. Achromatopsia, the rarest kind of colorblindness, involves the absence of all three pigments. People suffering from this form of color blindness can only see in black, white and gray.
