What Gene Causes Color Blindness

But sometimes color blindness is not.

What gene causes color blindness. Inherited color blindness color blindness from gene mutations. Usually genes inherited from your parents cause faulty photopigments molecules that detect color in the cone shaped cells or cones in your retina. It is most commonly inherited from mutations on the x chromosome but the mapping of the human genome has shown there are many causative mutations mutations capable of causing color blindness originate from at least 19 different chromosomes and 56 different genes as shown online at the online mendelian inheritance in man omim.

Blue yellow color blindness and complete color blindness are passed down on other chromosomes so they affect males and females equally. However research has shown that mutations that can lead to color blindness originate from in excess of 19 different chromosomes and many different genes. In the genetics the gene that determines color blindness is a recessive trait whereas normal color vision is the dominant trait.

Color blindness is typically an inherited genetic disorder. 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. In addition to genetic reasons there are some rare occasions where color blindness can be caused by non genetic factors.

Red green and blue colour blindness is usually passed down from your parents. Inherited color blindness is usually the result of receiving a genetically mutated gene on the x chromosome. Other less common forms of color blindness result from changes in the opn1 sw gene blue cone monochromacy or alterations to the opn1 mw dna sequence blue yellow color blindness 2.

Colour blindness is a usually a genetic hereditary condition you are born with it. Over 50 genes have been associated with color blind genetic traits and many of them are found on the x chromosome leading people to consider color blindness an example of an x or sex linked trait. A color blindness gene is a gene linked with colorblindness.
