What Mutation Causes Color Blindness
Most people understand color blindness to be a pre set condition that remains constant however depending on the mutation inherited color blindness can be progressive and unfortunately potentially lead to full blindness.
What mutation causes color blindness. Eight to ten percent of all males and one half of a percent of all females are color blind. To have red green color blindness both x chromosomes would need to have the gene for red green color blindness. Blue yellow color blindness and complete color blindness are passed down on other chromosomes so they affect males and females equally.
Color blindness is typically an inherited genetic disorder. According to certain studies it has been found these mutations originate from 19 different chromosomes and 56 different genes. Red green and blue colour blindness is usually passed down from your parents.
Color blindness is a common inherited sex linked disorder that affects a person s ability to see or recognize certain colors. Monochromacy total color blindness dichromacy. Continued what causes color blindness.
However there s no cure for inherited color blindness. The genes that produce photopigments are carried on the x chromosome. Color blindness is classified according to cause as well.
Now researchers have discovered that some people with the gene mutation that causes colorblindness lose an entire set of color cones with no detriment to the acuity of their vision overall. Mutations in these genes can cause color blindness. Females have 2 x chromosomes one from their mother and one from their father.
The gene which is responsible for the condition is carried on the x chromosome and this is the reason why many more men are affected than women. Usually genes inherited from your parents cause faulty photopigments molecules that detect color in the cone shaped cells or cones in your retina. Inherited color blindness can be active from birth or manifest during childhood and early adulthood.
If some of these genes are missing or damaged color blindness will occur. Their retinas look like swiss cheese with black holes where red or green cones should be. Photopigments are in both the rods and cones of the eyes.
Inherited color blindness occurs due to mutations on the x chromosome. If color blindness occurs as the result of illness or injury treating the underlying cause may help to improve color detection.
