The Genetics of Albinism
Oculocutaneous albinism is an abnormal coloring of the pigmentation of eyes, hair, and most
especially the skin (Genetics Home Reference). Too much sun exposure increases the damage to
the skin which can be developed into skin cancer. It also decreases the pigmentation of the iris
and the retina’s light-sensitive tissue. An individual with albinism are having problems in their
vision like involuntary movements of the eye, more sensitive to light, and reduces sharpness.
According to Genetic Home Reference, there are various types of albinism that can be identified
through the changes in the color of their skin, eye, as well as hair which is caused by genetics.
The type 1 albinism can be identified by the white hair, light-colored irises, and having the palest
skin. Type 2 has light yellow or brown hair and the skin’s color is creamy white. Type 3 is
categorized as having milder abnormalities in vision. And Type 4 has the same symptoms as
with the Type 2 albinism.
Albinism is an inherited disorder due to non-producing melanin pigment that determines the
eyes, hair and the skin’s color. This is caused by various genes’ mutation that is inherited
through autosomal recessive. There are different patterns in inheriting albinism. The
Oculocutaneous albinism affects the skin, eyes, and the hair. This is inherited in a manner of
autosomal recessive where the copied chromosomes, as well as the genes, are inherited both
from the mother and the father. Each of the parents is a carrier of causative gene’s functional
copy as well as a non-functional copy. It is a defective gene that does not show any signs of
albinism condition. When both parents are carriers of the condition autosomal recessive, there is
a 255 risk that a child can have the chance to be affected by albinism during pregnancy, 50% can
be an unaffected carrier like the parents, and 25% chance for the child to be not carrying this
