Albinism

A genetic disorder found in both humans and animals

Albino Description

Albinism is a mutation-caused genetic disorder which can cause paleness in the hair and skin as well as vision problems and many other side conditions. The science behind the white discoloration is because melanin is not present, which causes pigmentation to be nonexistent. In other words, your body does not have the coloration of skin hair and can cause iris (in the eyes) problems, too.

How Albinism is Obtained

Albinism is an autosomal recessive trait, which means it is NOT linked to X or Y chromosomes. However, this is somewhat rare due to the fact that very few people each year are born with albinism (Approx. 1 out of 20,000 in the U.S.). The trait can be minor (in lots of cases) and major forms of albinism are very rare.

How Albinism is Passed Down

Since albinism is an autosomal recessive trait, the parents would have to either...


-Both be heterozygous (One allele for albinism, one allele not for albinism) 25% chance of albinism


-1 is heterozygous, 1 is homozygous recessive (Dominant and Recessive & Recessive and recessive) 50% chance of albinism


-Both are homozygous recessive (Two alleles for albinism) 100% chance of albinism

Prognosis

The prognosis for albinism is unique from some other genetic disorders. Life expectancy is the exact same as humans without the condition, although vision problems can lead to bad vision in life. Most life-changing eye symptoms are curable, and albino people can easily have these obstacles moved out of the way and focus on life goals. Skin tone shouldn't pose as a restriction for anything, and albinos should have the opportunities that all other humans have.
