Albinism

Albinism is not a disease. People with albinism have little or no pigment in their eyes, skin, or hair. They have inherited altered genes that do not make the usual amounts of pigmment called melanin. Albinism affects people from all races. Most children with albinism are born to parents who have normal hair and eye color for their ethnic backrounds. There are different types of albinism, but all forms are associated with vision problems.

if you lack a dark brown pigment (melanin) in your skin, eyes, and hair

it may result in vision problems

Normally both parents have to have the recessive gene for the particular trait that causes complete or partial albinism. Therefore it will appear more frequently in families with a history of albinism.

Ocular albinism (OA1) is caused by a genetic defect on chromosome 11 of the GPR143 gene.

Oculocutaneous albinism type 2 (OCA2 or P gene albinism) results from a genetic defect on chromosome 15 in the P protein that helps the tyrosinase enzyme to function.

Oculocutaneous albinism type 3 (OCA3) is rarely described and results from a genetic defect on chromosome 9 in TYRP1, a protein related to tyrosinase.

Oculocutaneous albinism type 4 (OCA4) results from a genetic defect in chromosome 5 at position 13.3, in the SLC45A2 protein that helps the tyrosinase enzyme to function.

I think no. It's caused by a recessive gene so if a person has albinism their genotype can only be recessive, recessive ---> AA (small a small a or whatever you call it). No other genotype will mean that person has Albinism, like if it has at least one big A, that means it's just a carrier of albinism.

Melanism is rarer than Albinism

The difference in longevity between normal people and people with albinism is not well researched. Scientists believe their longevity to be comparable to that of normal people.

Virtually every species of animal has a rare recessive gene mutation that causes the inability to make pigmentation. Their eyes are often very sensitive to sunlight, and they run risk of skin disorders generally from absorbing too much sunlight.

An albino lion would be almost pure white, or perhaps a little pink.

There apparently is also a gene for a white lion due to a recessive gene called: chinchilla or color inhibitor. These aren't considered true albinos. White isn't a particularly good color for lions to be stealthy... but humans have attempted to increase the numbers of individuals expressing these genes.

Albinism doesn't affect a person's life expectancy. People with albinism may be limited in their activities because they can't take exposure to the sun, but their overall lifespan should remain unchanged.

No, not at all. Though because of the light skin and sensitivity to sunlight, albinos are at a larger risk of skin cancer.

yes, of course!! people with aids/cancer/progeria/diabetes can dye their hair. right?

EDIT***

Actually, no, they cannot. When someone is Albino, their hair has no pigment, which means that holding and locking in color is extremely difficult.

ANSWER:

YES!!!! i am albino, i have done it before. but let me say it is a looooot harder to do than color hair but it is a longer processes

ANSWER:

I really wouldn't! I'm a teenager with albinism and with my experience in the salon today I'm never going near hair dye ever again! Originally, i was going to get low lgihts. I had a test strand done a few weeks earlier and it was fine. However I changed my mind and we decided to do a glaze instead of a dye because eventually they said my roots would turn grey. They started putting this nice golden blonde color in my hair and we literally watched my hair turn GREY in minutes ! They rushed me to the sink to get it out. They managed to get most of it out but my hair doesn't look the same and it won't for a few weeks. I really wouldn't do this if you aren't 100% positive your hair will take the color correctly.

ANSWER:

I am 43 year old albino and have been getting my hair colored since I was 18. The very first time the lady butchered it and turned my hair orange. But that was a very long time ago. The place I have been going to over the past 15 years have been fantastic. The first product that they used to put on burned really bad, but was necessary. Now the product hardly burns at all. You simply have to find a place that is willing to keep trying until they get it right. Ask first if they will, if not go elsewhere. Its your money, and its their job to satisfy what you want.

About this Yes people with Albinisme can dye their hair with Hena my color is just brown/redish so that you know that

Yes. They tend to have pale blonde or yellow hair, pink eyes, pink skin, and usually have eye problems. This can occur in any race.

The lack of pigment in the eyes of people with albinism changes the light index of the lens which leads to refractive issues such as extreme farsightedness. They may also have problems with glare.

yes it can be but that is not always the case albinism is a genetic disorder that can just happen for no particular reason like a baby being born with an organ failure or a missing arm or whatever it is not allways passed down from the parents and it can skip gnerations

hope this helped

life is a little harder when you have to have assitance to find what to wear and to compare things.

From all I have read and studied (I am a 2nd semester senior nursing student at a major university) Spina Bifida is not so much a chromosomal defect as a neural defect caused by a lack of folic acid during the very early stages of pregnancy.

This is why women who wish to get pregnant are encouraged to begin taking folic acid BEFORE they actually get pregnant.

One would define albinism as either a complete or partial absence of skin, hair, and eye pigment. This is due to the deficiency of an enzyme called tyrosinase, which is involved in the production of melanin.

It is passed on from mother or father to child if the parents are albino, or if the mother carries the gene for albinism. The father cannot carry the gene as only woman are able to be carriers. Therefore, even if both parents are normal, the child can be albino (because the mother obviously carries the gene for albinism).

:D

Albinism is a genetic defect where the person afflicted is homozygous recessive for albinism. So it cannot be cured.

Topical treatment involves wearing clothing or sunblock to avoid skin damage, as there is usually not enough melanin to tan the skin. Protecion of the eyes, which also lack pigment in the iris, is also a concern. This can lead to retinal damage in some individuals, and should be monitored.

1 in 17,000, or 0.0059%

1 in 70, or 1.4% are carriers.

The estimated 2007 population of the US is 302,854,000

Albinism's effects vary with its severity, with outcomes ranging from combined pigment loss in the hair, skin and iris to pigment loss limited to the retina.
