People with albinism have a reduced amount of melanin, or no melanin at all. This can affect their colouring and their eyesight. People with albinism often have white or very light blonde hair, although some have brown or ginger hair. The exact colour depends on how much melanin their body produces.

What are the 4 types of albinism?
To date as many as seven forms of oculocutaneous albinism are now recognized – OCA1, OCA2, OCA3, OCA4, OCA5, OCA6 and OCA7. Some are further divided into subtypes. OCA1, or tyrosinase-related albinism, results from a genetic defect in an enzyme called tyrosinase.
Does albinism affect all races?
Albinism affects people from all races. Most children with albinism are born to parents who have normal hair and eye color for their ethnic backgrounds. Some patients with albinism have white hair and very light blue eyes, others have blonde hair and blue eyes, and some even have brown hair and eyes.
Can 2 albinos have a normal child?
This means a child has to get 2 copies of the gene that causes albinism (1 from each parent) to have the condition. If both parents carry the gene, there's a 1 in 4 chance that their child will have albinism and a 1 in 2 chance that their child will be a carrier.
What race has the most albinos?
Albinism affects people of all ethnic backgrounds; its frequency worldwide is estimated to be approximately one in 17,000. Prevalence of the different forms of albinism varies considerably by population, and is highest overall in people of sub-Saharan African descent.
Are albinos rare?
Albinism is a rare group of genetic disorders that cause the skin, hair, or eyes to have little or no color. Albinism is also associated with vision problems. According to the National Organization for Albinism and Hypopigmentation, about 1 in 18,000 to 20,000 people in the United States have a form of albinism.
Do albinos smell bad?
Close relatives of Caucasian albinos have described to me their odor as sour, fishy and fetid. A Cuna Indian mother of both albino and brown-skin children said that she could wash her albino babies with soap and immediately they smelled as though they had not been washed for two weeks.
Why do albinos eyes shake?
Nystagmus (the back and forth movement of the eyes) as well as the lack of pigment in the iris and the retina are also contributing factors to our reduced vision, although to a lesser degree. The easiest way to understand how the lack of cones affects the vision of people with albinism is to turn on your television.
What is the opposite of albino?
opposite of albinism. The word “melanism” comes from the Greek for “black pigment.” Adaptive melanism is inherited and helps certain species to be camouflaged in some environments, such as a black panther hunting at night.
Are gingers albino?
The red hair in African people is caused by a mutation in a gene called TYRP1. The protein made by this gene is thought to be involved in bringing together all the enzymes needed to make brown melanin. So redheads of African descent completely lack brown melanin and are therefore albino.
Can you be born with white hair and not be albino?
What is poliosis? Poliosis is when a person is born with or develops a patch of white or gray hair while otherwise maintaining their natural hair color. It can affect both children and adults.
Do albinos live long?
Albinism is not associated with mortality. Lifespan is within normal limits. Because the reduction of melanin in the hair, skin, and eyes should have no systemic effects, the general health of a child and an adult with albinism is normal.
Why is albinism more common in Africa?
Albinism is more common in East Africa because rural tribes have a more isolated genetic pool, and because the society is less mobile.
Can you be partially albino?
"It is simply impossible, just like being 'partially pregnant' ". Conditions that are commonly termed "partial albino" include neural crest disorders such as piebaldism, Waardenburg syndrome, or other depigmentation conditions such as vitiligo.
Which country has most albinos?
Fiji has one of the highest rates of albinism in the world.
