Case study #13 Red-Green Colorblindess

How does it affect the individual?

Prompt 1

How does it affect the invididual?

It causes the individual to suffer from color vision deficiency. The disorder causes mutations in the OPN1LW, OPN1MW, and OPN1SW genes causing color vision deficiency.

Prompt 2

What causes the disorder?

How is it inherited?

Red-green color blindness or Deuteranopia, is inherited through genes on the X chromosome, more common in males who inherit the gene from their mother. Females usually carry the gene without being color blind themselves, passing it to their children.

It is sex-linked and mutations in the OPN1LW, OPN1MW, and OPN1SW genes cause the individual to suffer from color vision deficiency.

Prompt 3

What chromosomes are affected?

Red-green color blindness is primarily associated with genes located on the X chromosome.

Treatments/Management of the Disorder

Looking back at the punett squares, there is a 50% chance that the child will be completely unaffected by the disorder. There is a 25% chance that the child is a carrier of the gene but doesn't show symptoms. There is a 25% chance the child is affected by the gene and has red green color blindness. The percentage 50/25/25

Deuteranopia currently has no treatment/cure.
