Autosomal recessive inheritance pattern Autosomal recessive inheritance pattern To have an autosomal recessive disorder, you inherit two mutated genes, one from each parent.

These disorders are usually passed on by two carriers. Their health is rarely affected, but they have one mutated gene recessive gene and one normal gene dominant gene for the condition.

With each pregnancy, two carriers have a 25 percent chance of having an unaffected child with two normal genes lefta 50 percent chance of having an unaffected child who is also a carrier middleand a 25 percent chance of having an affected child with two recessive genes right.

Several genes provide instructions for making one of several proteins involved in the production of melanin. Melanin is produced by cells called melanocytes, which are found in your skin, hair and eyes.

Albinism is caused by a mutation in one of these genes. Different types of albinism can occur, based mainly on which gene mutation caused the disorder. The mutation may result in no melanin at all or a significantly reduced amount of melanin. Types of albinism Types of albinism are classified based on how they're inherited and on the gene that is affected.

Oculocutaneous albinism OCAthe most common type, means a person inherited two copies of a mutated gene — one from each parent autosomal recessive inheritance.

OCA causes decreased pigment in the skin, hair and eyes, as well as vision problems. The amount of pigment varies by type, and the resulting color of skin, hair and eyes also varies by and within types.

Ocular albinism is mainly limited to the eyes, causing vision problems. The most common form is type 1, inherited by a gene mutation on the X chromosome.

X-linked ocular albinism can be passed on by a mother who carries one mutated X gene to her son X-linked recessive inheritance. Ocular albinism occurs almost exclusively in males and is much less common than OCA.

Albinism related to rare hereditary syndromes can occur. For example, Hermansky-Pudlak syndrome includes a form of OCA as well as bleeding and bruising problems and lung and bowel diseases.

Chediak-Higashi syndrome includes a form of OCA as well as immune problems with recurrent infections, neurologic abnormalities and other serious issues. Complications Albinism can include skin and eye complications as well as social and emotional challenges.

Eye complications Problems with vision can impact learning, employment and the ability to drive. Skin complications People with albinism have skin that is very sensitive to light and sun exposure.

Sunburn is one of the most serious complications associated with albinism because it can increase the risk of developing skin cancer and sun damage-related thickening of the skin. Social and emotional challenges Some people with albinism may experience discrimination.

The reactions of other people to those with albinism can often have a negative impact on people with the condition.Get the latest health news, diet & fitness information, medical research, health care trends and health issues that affect you and your family on rutadeltambor.com Sclerotherapy is a medical procedure whereby a chemical, the sclerosant, is injected into a vein to entirely obliterate it.

The sclerosant damages the innermost lining of the vessel (the endothelium), resulting in a clot that blocks the blood circulation in the vein beyond.

Albinism is a defect of melanin production. Melanin is a natural substance in the body that gives color to your hair, skin, and iris of the eye. Reduce sunburn risk by avoiding the sun, using sunscreen, and covering up completely with clothing when exposed to the .
