Albinism

This man was born with Oculocutaneous albinism, the most recognized type. Oculotaneous albinism affects the skin, hair, and eyes, making him appear milky-white in complexion, and pink eyes due to lack of melanin, the protein which determines coloring in the body and is crucial to eye development. Eye disorders are common with albinism.

Albinism is a genetic disorder passed through families as a recessive disorder. It affects melanin production in the body, causing the person affected to have pale skin, hair, and discolored eyes. People with albinism often have vision problems and are more susceptible to sunburn and skin cancer.

Albinism

Albinism is inherited through families. It can be through autosomal homozygous inheritance, or other types through sex-linked recessive inheritance. The Punnet square below shows different scenarios where someone would have the disorder or be a carrier, as shown in the pedigree.

Albinism cannot be prevented or cured after conception. It can, however, be treated by closely observing it and taking careful measures, such as regular physical and eye checkups.

When you have albinism, you lack an enzyme called tyrosinase, which makes melanin from tyrosine, an important amino acid in your DNA. Without melanin, there is no pigment in your skin to absorb the sun's UV-rays, and you are at high risk of skin damage.Melanin is also essential to eye development, which is why albinos tend to have eye disorders, such as nystragamus, amblyopia, optic nerve hypoplasia, etc.
