overview
The term albinism generally refers to oculocutaneous albinism (ok-u-low-ku-TAY-nee-us) (OCA) – a group of hereditary diseases in which little or no melanin pigment is produced. The type and amount of melanin your body produces determines the color of your skin, hair, and eyes. Melanin also plays a role in the development of optic nerves, so people with albinism have vision problems.
Signs of albinism can usually be seen in a person’s skin, hair, and eyes color, but sometimes the differences are small. People with albinism are also sensitive to the effects of the sun, which puts them at increased risk of developing skin cancer.
Although there is no cure for albinism, people with this disorder can take steps to protect their skin and eyes, and to maximize their eyesight. Albinism Treatment in Nizamabad

The reasons
- Autosomal recessive inheritance model
- Autosomal Recessive Inheritance PatternOpen Context Dialog
- Several genes provide instructions for making one of the many proteins involved in melanin production. Melanin is made by cells called melanocytes, which are found in the skin, hair, and eyes.
- Albinism is caused by a mutation in one of these genes. Different types of albinism can occur, mainly depending on the gene mutation that is causing the disorder. The mutation can result in the absence of melanin at all or a significantly reduced amount of melanin.
prevention
If a family member has albinism, a genetic counselor can help you understand the type of albinism and the chances of having a future child with albinism. It can also explain the tests available. Albinism Treatment in Nizamabad
