This is a power point on albinism.

1. Albanism

2. Albinism is a point mutation. The cause for the point mutation (insertion, deletion, inversion) depends on the case.

3. The most well common and well known form of albinism isoculocutaneous albinism. There are four forms of this kind of albinism; OCA1, OCA2, OCA3, and, OCA4.

4. Symptoms Little to no pigment, depending on the form of the disorder, in the hair, eyes, and skin. Eye problems such as poor eye sight, cross eyes, and oversensitivity to light Most albinos have astigmatism. Susceptibility to sunburn and skin cancer

5. Prognosis Albinism does not improve or worsen over time. Life expectancy is not altered by albinism, however albinos are more susceptible to skin cancer via prolonged exposure to the sun.

6. Incidence About 1/17,000 people suffer from albinism in the United States and Europe, however occurrence of the disorder is much higher in Africa and Asia, reaching up to 1/5,000 in parts of the world. About 1 in 70 Americans is a carrier the flawed gene required to have an albino child.

7. Inheritance Albinism is inherited through genetically recessive alleles. Therefore if an individual receives a mutated tyrosinase gene, the gene whose mutation causes OCA2, from the father, but not the mother, he or she will be a carrier of albinism, but will not suffer from albinism.

8. Treatment While there is no method of treating the symptoms of albinism, there are precautions that sufferers can take such as wearing lots of clothing so as not to leave the skin exposed, wearing lots of sun block, and keeping out of the sunlight. Glasses can be prescribed to those with vision problems, and in severe cases eye muscle surgery is an option.
