Introduction: An Albino Overview
Name comes from Latin "albus," meaning "white." It is also occasionally known as lso called achromia, achromasia, or achromatosis.
A congenital disorder.
A congenital disorder (or disease) is a defect existing at birth. Of these disorders, those characterized by structural deformities of the body are known as "congenital anomalies" and involve either physical damage to a developing fetus, or genetic mutations in the development of said fetus.
Reasons for the occurrence of congenital anomalies may include the inheritance of damaged or abnormal genes from either of the parents, or a newly occurring mutation in a germ cell that the fetus gave rise to. If an egg is fertilized with sperm that has damaged DNA, there is a chance that the fetus will develop abnormally.
Genetic diseases come in several varieties: Single-defect, multi-defect, or chromosomal.
Single-defect diseases arise from inheriting two copies of a damaged respective gene, or one copy of a dominant gene.
Multi-defect diseases are the result of numerous damaged genes.
Chromosomal disorders occur in loss or duplication of larger parts of chromosomes, often affecting significant body parts.
Characterized by the complete or partial absence of pigment in the skin, hair and eyes due to absence or defect of tyrosinase.
Tyrosinase is an enzyme that controls the production of melanin.
It can be found inside synthesised melanosomes in the skin.
It also catalyzes production of melanin by oxidation; if a fruit or vegetable is left out for a few days and blackens, tyrosinase is at work.
Biological pigment is a substance produced by an organism that allows it to project color through...

Tyrosine is converted into one of two types of melanin: eumelanin (“black-brown”) or pheomelanin (“red-blond”). Mutations affecting proteins and/or enzymes in the way of melanin’s path result in little to no melanin production (by lack of tyrosine being converted into melanin via the enzyme tyrosinase).
Mutations to the tyrosinase enzyme cause OCA type 1 and OA, the most common and easily explainable.
The “P” protein is involved in the movement of tyrosine before it synthesizes to form melanin. If this gene is damaged, the outcome with be OCA type 2.
Elimination of the Damaged Gene:
Albinism can’t be cured, seeing as it’s a congenital disease.
The effects of it, however, can be treated.
Selective breeding is the easiest way to eliminate the risk of albinism; unfortunately, this probably isn’t a very realistic way to do it.

- Albinism is a genetically inherited disease that leads the patient to have little to no melanin, which causes a loss of pigment in hair, skin, eyes, and a decrease in vision. There are different forms of albinism, but the two most popular are called Oculocutaneous Albinism and Ocular Albinism. Oculocutaneous Albinism has a pigment deficiency in skin, hair, and eye color, along with decreased vision in the eyes. Ocular Albinism has a defect in the eyes affecting vision, but there is no difference in skin and hair color (4).... [tags: Albinism, Human skin color, Melanin, Allele]

- Albinism is a person with congenital absence of pigmentation in skin, eyes, and hair (Dictionary 1). Albinism is also known as achromia, achromasia, achromatosis. Albinism is mainly known as a genetic condition. Many people in the United States are affected with a type of Albinism. People that have Albinism suffer from vision problems and are easier to get sun burns and skin cancer than others who do not have Albinism (What is Albinism. What Causes Albinism). A sign that a person can have Albinism is that they have a little pigmentation in their eyes.... [tags: Albinism Essays]

- Introduction: Recent advances in science and technology has shown a great impact on all areas of the life. One of the most important fields of science and technology is Biotechnology. The advancement in biotechnology brought forward the solutions for many of the problems that human race were facing, including the problem of feeding a large population but at the same time, it poses some new threats and challenges to human beings as well. This short report discusses the merits and demerits of extensive applications of biotechnology, specially the impacts of genetically modified/engineered crops which brought up in market 1990s....

- In December 2008, the University of Kuwazulu Natal in South Africa granted me a full scholarship and admitted for a PhD study on Algal Biotechnology project. My project specifically researched on Polyamines Extracts from Kelp Algae and their effect on plants. And was engaged in experimenting till the last-minute I left South Africa. After a good seven months of school, the South African Home Affairs send me a letter rejecting my refugee application after almost five years. Very frustrated, wrote a long appeal letter....

- Albinism: A Genetic and Social Interpretation Introduction The effects of albinism have profound phenotypic distinctions that are visibly defining between those who are affected and those who are not. However, it is the cultural belief and social stigmas surrounding albinism that has brought attention to the mutation in recent media. Ostracizing, rape, and murders of albinos, have steadily increased over the years in the southern African continent. It is due to the myths, beliefs, and misunderstandings about the condition that has left room for stigmas surrounding the condition.... [tags: Genetics]

- There are many definitions of biotechnology. It has been described as including any technique that uses living organisms to make or modify products, to improve plants or animals or to develop microorganisms for specific uses. It has also been defined as the industrial exploitation of biological systems or processes. In its broadest sense, biotechnology refers to the use of living systems to develop products. New scientific discoveries are allowing us to better understand fundamental life processes at the cellular and molecular level.... [tags: Biotechnology Research Paper Globalization]

- Page:1 Albinism is a very serious disease that could end up in death. Albinism is a recessive inherited defect in melanin, which is metabolism in which pigment is absent from skin, hair, and eyes. Albinism in hair, skin, and eyes is called oculocutaneous albinism. Humans that have oculocotaneous albinism are not able to produce melanin. These people have white, yellow, or yellow brown hair, very light ( usually blue ) eyes, and very pale skin. Their eyes may appear pink because they have very little pigment....

- The Genetic Defect Albinism In the past, albinos were usually treated with fear or awe. They were sometimes killed at birth. Albino births were common enough in some groups not to cause any excitement. For example, among the San Blas Indians of Panama, one in approximately 130 births is an albino. In the mid-nineteenth century, albinos were exhibited in sideshows. Whole families were displayed at times and were described as a unique race of might people. They were said to live underground and to come out only at night when the light was dim and would not hurt their eyes.... [tags: Papers]

- Albinism ALBINISM Albinism. The word albinism refers to a group of inherited conditions. People with albinism have little or no pigment in their eyes, skin, or hair. Recently a test has been developed to identify carriers of the gene for ty-neg albinism and for other types in which the tyrosianase enzyme does not function. The test uses a sample of blood to identify the gene for the tryrosinase enzymes by its code in DNA. The above test does not apply to to one type of albinism, called X-linked ocular albinism....
