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.
Color blindness, also known as color vision deficiency, is the inability to distinguish colors and shades or to recognize them at all. It occurs when the color-sensing cones of the retina are absent or do not function properly. About 8 percent of males and 1 percent of females are color-blind to some degree. Most color-blind people have difficulty in distinguishing among various shades of the same color or seeing some colors as brightly as others; the inability to distinguish any colors at all and see the world in black-and-white is rare. Most color blindness is inherited and present at birth.
