Rarely seen in person, with pale fair skin, white like a gray hair, eyebrows and lashes. All right, the hair these people devoid of pigmentation, like the epidermis, so they are not able to sunbathe. Call this congenital albinism, and people, carriers of the defective gene – albinos.
In our time of high radioactivity, bad food, bad habits and bad heredity of the genetic variance in the set of incidence, so the number of "white" people in the world is growing. Still some people ascribe magical properties, and others, however, do not accept albinos in society, considering them to be, pardon the pun, "black sheep". This position is extremely ignorant, as man has no effect on what set of chromosomes, it can be born. To treat congenital defects and defects of scornful means to be inhuman and inhumane.
Today we have collected 10 interesting facts about people with albinism that will help enlighten the population about the aspects of the disease and instill in them the right attitude towards it.
10. Albinism is not uncommon
Yes, many people live life not seen the albino, and it is not surprising, because according to statistics, only 1 person out of 20 thousand suffering from an unusual disease. In the cities at the same time can accommodate about 50 albinos – and this is not uncommon, as they are also moved to transport, visit public places and social institutions, and sometimes manage to get on local TV as an invited guest. By the way, among representatives of the Negroid race people without pigmentation more. But if you take the whole planet, the whole 1% of the world population – people with albinism. A carrier of the recessive gene of this disease is, in theory, every 70 people.
9. Different types of albinism
Few people knows that the depigmentation from the albino can be primary (congenital) and secondary (acquired). All depends on the degree of the blockade of the secretion of the enzyme tyrosinase, which is responsible for producing the melanin pigment that provides color to our dermal. Full albinism is accompanied by concomitant eye diseases (cataract, impaired vision, strabismus), photophobia, abnormalities of the skin (dryness and sensitivity, propensity to burn) and other pathologies. But a partial or incomplete mountaineering is more a visual issue that appears white lesions-spots the gray strands in her hair, depigmented eyebrows or eyelashes.
8. Albinism congenital disease
Basically albinism is congenital in nature. The child passed the defective genes that will block the melanin production. If both parents are carriers of the gene of this disease, the risk of a baby albino is 25%. In the case where one parent has a normal gene, it will be sufficient for the synthesis of melanin. If the history of your family once there have been cases of albinism, then you can check your carrier. It's enough to give the scientist to test in the laboratory the follicle of your hair on the ability to produce melanin.
7. One of the 17 000
In fact, one of the 17 thousand people in any case there is full or partial form of albinism. For the disease there is no separation by gender, only by race. However, it was noted that men more common form of eye disease – when the iris is also devoid of pigmentation.
6. Albinism can pass
It is believed that in the presence of the defective gene medicine is powerless – it is. Medication for albinos haven't figured out a partial form revise solely cosmetic techniques and plastic surgery. However, there are cases when kids with a simple form of the disease light skin, hair, eyelashes and eyebrows have gradually acquired pigmentation with growing up.
5. Vitamin D
Scientists estimate that people are albinos, despite the lack of ability to sunbathe, produced valuable for of the skin and musculoskeletal system vitamin D is 5 times faster than others. What is this mystery? The fact that vitamin produced in the skin when ultraviolet rays with a spectrum (e.g., solar) get into it. This means that melanin pigment is a kind of barrier that prevents a more complete absorption by the dermis ultraviolet radiation and, accordingly, the production of vitamin D. However, albinos cannot tan because of the severe photophobia.
4. Animals-albinos – are not uncommon
Defective recessive gene can be detected not only in humans but also in the mammal, reptiles, birds and other fauna. Of course, as people, so animals are more difficult to get along with other dogs – those that don't accept outlandish representative in his pack. And with predators animals-albinos unlucky as noticeable disadvantageous colouring makes them stand out compared to other relatives and the world in General. In addition, females mostly choose the most "colored" members, and depigmented pay attention at the last moment. Interestingly, animals have disease-antagonist of albinism called "melanism". In this case, the representatives revealed the prevalence of the dark color pigment.
3. Albinism does not require treatment
Despite the fact that albinism is a disease – it does not require treatment. Albinos are a way of life in physiological and psychological development do not differ from other, live to be average, according to statistics, years. Another thing that people with albinism are often found accompanying symptoms and pathology, which require competent care. This and photophobia, and pathology of the organs of vision, and disorders of hemostasis. We should also mention the problem of the skin and a tendency to Allergy, hypersensitivity, dermatitis, high risk of oncological processes. Vaccine or treatment for albinism yet, as have not learned to intervene in the genetic code already born person.
2. Albinism is most common in Africa
Statistics says that people with albinism are approximately 6 times more likely to appear among the African people. 3 thousand inhabitants 1 albino. Pathology is more common in East Africa, and the highest concentration is reached in Tanzania (in average there are albinos in 15 times more, than in any other region of the world, that's 1 persons 1.4 million). In Burundi and Kenya the ratio of albinos and normal people is about 1 to 5 thousand Exact reason why there is this variation, scientists can not name.
1. Persecution of people with albinism
About people with this disorder has long been spread various rumors. On the background of the superstition they were hunted warlocks, wanting to get part of the body, supposedly endowed with special power. Other people on the contrary believed albinos almost gods-healers, which could eliminate human misery. Rumored to be in Tanzania on the black market the price of a limb of an albino can reach 75 thousand dollars. Media and culture the subject of albinism often ridiculed or put people socially dangerous, defective, underdeveloped.
Modern man, having knowledge about albinism, can try to support people, to help them to adapt to society, to organize jobs. Be humane toward the people.
