There are a few reasons why I chose albinism as my topic. First and foremost, in kindergarten I had a friend who was an albino, and although I have not seen him in over 10 years I am still curious as to what the causes of albinism are.
Another reason I am curious about albinism actually extends from my first reason.
I often wondered if there was any chance that my kids could possibly be born with it. I also used to wonder whether or not my friend could see the same way I could, since his eyes looked so different from mine. As a result of all of this, Albinisim essay could not turn down the opportunity to research a disease that has held my curiosity for such a long time.
Albino skin is whitish in appearance, sometimes seeming to be almost translucent. Similarly, albino hair is also very pale, appearing closer to white than blonde.
Albinism makes the skin extremely sensitive to sunlight. Albinos need to be very careful about exposure to the sun as they have a very high risk of burning due to lack of protection from ultraviolet rays, which is normally provided by the pigment melanin 2.
Similar to the skin, albino eyes also lack color; the irises usually appear pinkish. People with albinism often have eye problems. First of all, they suffer from severe sensitivity to bright lights.

Albinism also affects people of all races equally. Approximately 1 in 17, people has one of the types of albinism, which amounts to roughly 18, people in the United States 1.
The gene associated with albinism is called OCA1 among a few others. OCA1 codes for the protein tyrosinase. This protein is responsible for converting tyrosine into something called DOPA dihydroxyphenylalanine.
DOPA plays an important part in the formation of melanin by next becoming dopaquinone. Dopaquinone then forms black-brown eumelanin or red-yellow pheomelanin.
