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.
There is no actual blindness but there is a deficiency of color vision. The most usual cause is a fault in the development of one or more sets of retinal cones that perceive color in light and transmit that information to the optic nerve. This type of color blindness is usually a sex-linked condition.wo of the most common inherited forms of color blindness are protanopia and deuteranopia. One of the common color vision defects is red-green deficiency which is present in about 8 percent of males and 0.5 percent of females of Northern European ancestry.
