About

Albinism is a congenital disorder characterized by the complete or partial absence of pigment called melanin in the skin, hair and eyes. It is also known as hypopigmentation, oculocutaneous albinism or ocular albinism.

Albinism

This is an autosomal recessive type of inherited disorder, which means that the chance of the disorder being passed from one generation to the next is low. Statistics show that about 1 in 17,000 people suffer from some form of albinism.

Albinism is an inherited defect affecting melanin production and metabolism. Melanin is a naturally occurring pigment, which is responsible for the color of our skin, hair and eyes. It protects the skin from the harmful effects of ultraviolet light. Therefore, people in the tropics are darker as their sun exposure is more, in comparison to the people who live in temperate climates. If the gene encrypting this pigment is defective, the body becomes pale and white.

People who are affected by albinism are called albinos. They have absence of color in the hair, skin, or iris of the eye; or lighter than normal skin and hair. Lack of skin pigmentation makes albinos more susceptible to sunburn and skin cancers. Vision problems like extreme far-sightedness or near-sightedness, nystagmus, strabismus, photophobia and astigmatism are common in people with albinism.

Albinism can be diagnosed merely by observation of major or total absence of pigmentation of the skin, hair and eyes. Genetic testing, electroretinogram, chemical testing of hair and blood tests aid in diagnosing albinism.

There is no cure for albinism. Treatment is aimed to ease the symptoms. Treatment of the eye conditions consists of visual rehabilitation. It is important that albinos use sunscreen before sun exposure to prevent premature skin aging or skin cancer.

Albinos can live a normal life span, however, some forms of albinism can be life threatening. The lives of people with Hermansky-Pudlak syndrome can be shortened by lung disease. People in tropical countries who do not use skin protection may develop life-threatening skin cancers.

Albinism may cause social problems, because people with albinism look different from their families, peers, and other members of their ethnic group. There is no known way to prevent albinism. Genetic counseling should be considered for individuals with a family history of albinism or hypopigmentation.

i would like to clarify something. i am a Nigerian girl with albinism. i have a light complexioned skin and yellow-blonde hair. i do not regularly use sunscreen but i go out on a daily basis. the sun is hot but i hardly get sun burns. generally, the sun is not good for anyone. don't put this as if albinos would melt under the sun. i wear long sleeved clothes but many times, i love short sleeved clothes just to flaunt my smooth skin. albinism is not a disability or a kind of sickness that requires treatment. one has to carefully take care of oneself. i see albinism as a mere variation, not a genetic disorder. at least, i have the chance to be African and non African [in terms of complexion and hair colour] at the same time. many people do not have that privilege. i also see clearly, without glasses. i use shades when i am outdoors, but not always. my eyes are green, not blue

hi i m an allied health professional and doing my research on the visual outcome with different optical aids of albinos to enhance their activities of daily life so plz any of u if have informaation about albinism plz send it on my id

Hi, I am an albinic girl. I am 29 years old. I am orried about if I marry a guy than shall I have a normal baby or an albenic. What are the risk factors. Please help

Yeah, in Biology, I learned things such as Punnet Squares. If 2 capital A’s are in the genotype [AA], then they are not albino. If 2 lowercase a’s are in their genotype (aa), then they will be. If it is one of each (Aa), then they will not be albino, but they can pass it on to their kids. You have aa. Someone without albinism in their family at all is AA. If you marry that dude, your child will be Aa (they will not show albinism, but they can pass it on to their kids. If they marry someone with AA, the child will have a 50% chance of AA and a 50% chance of Aa ). If you marry someone with albinism in their family (Aa [actually, they could be AA also, but it is unlikely {it all depends on the parents}]) then your child will have a 50% chance aa (full albino) and a 50% chance Aa (pass it on to their children). Hope that helps. For more info, Google Punnet Squares.

male cant pass any symptoms because, they are XY and only the X holds the phenotype. female are XX so they can pass the phenotype. also male that has it cant hide it, because there is only 1 X. the X holds the genes so female may get XA Xa and that hide the phenotype because there is another X with lower case a.

Can anyone tell me will my children have albinism if i marry a girl whose father have albinism?

awesome

you can go to genetic counceling to see if your children have a chance of having albinism. its all in genetics.

Yeah, just see 2 comments up [pink_y]. Or, just read what I commented here: Yeah, in Biology, I learned things such as Punnet Squares. If 2 capital A’s are in the genotype (AA), then they are not albino. If 2 lowercase a’s are in their genotype (aa), then they will be. If it is one of each (Aa), then they will not be albino, but they can pass it on to their kids. You have aa. Someone without albinism in their family at all is AA.
