Definition of leprosy disease
Leprosy is a genetic disease caused by the absence of melanin in the skin, hair and eyes, and causes skin and eye sensitivity when exposed to light. The essential function of melanin is to protect the skin from ultraviolet rays resulting from the sun. Because the eye is not fully completed, the male and female leprosy, a non-contagious skin disease that begins to appear since the birth of the child, is caused by different gene mutations that affect different points, leading to a decrease in the production of melanin Yen.
The shape of the sufferer with leprosy or leprosy is white, the skin is very white and pale and the color of the eyes is blue. The growth of people with leprosy is not affected naturally. Leprosy does not affect their health or fertility and the rate of birth of a leptemic child when a leprous person marries a non-leprous person Very few.
Causes of leprosy
- Optic dermatomastia: divided into four types:
- The first type of visual skin jugular is caused by a transgenic factor of tyrosinase, which encodes the tyrosinase enzyme. The function of tyrosinase forms the melanin dye of the amino acid tyrosine, affecting 70 species of mutations in this type of leprosy.
- The second type of optic dermatitis occurs because of a mutation in a genetic factor affecting the chromosome bodies.
- The third type of optic dermatitis occurs as a result of a mutation affecting the melanin pigment.
- The fourth type of optic dermatitis is caused by a mutation in the genetic factor of the membrane-related protein.
- Visual dilution is caused by mutation in the genetic factor found in X-rays.
People who suffer from lengthening need special care because of the sensitivity of their skin and eyes. Sometimes their eyes tend to reddish, and may be visually impaired. They may be visually impaired. Eyesight and skin may be called optic dystrophy. People with anorexia suffer from lack of vision or weakness, Eyes may require contact lenses or glasses to improve vision, especially when exposed to sunlight, and the disease can be treated with only a correction of the eye can not be more patient The leprechaun of the challenge Yat’s hearing, which is rare.
