The term albinism typically refers to oculocutaneous (ok-u-low-Ku-TAY-nee-us) albinism (OCA) — a group of inherited disorders where there is little or no production of the pigment melanin. 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 are usually apparent in a person’s skin, hair, and eye color, but sometimes differences are slight. People with albinism are also sensitive to the effects of the sun, so they’re at increased risk of developing skin cancer.
Although there’s no cure for albinism, people with the disorder can take steps to protect their skin and eyes and maximize their vision.
Symptoms of Albinism treatment
Signs and symptoms of albinism involve skin, hair, and eye color, and vision.
The most recognizable form of albinism results in white hair and very light-colored skin compared with siblings. Skin coloring (pigmentation) and hair color can range from white to brown and may be nearly the same as that of parents or siblings without albinism.
With exposure to the sun, some people may develop:
Moles, with or without pigment — moles without pigment are generally pink-colored
For some people with albinism, skin pigmentation never changes. For others, melanin production may begin or increase during childhood and the teen years, resulting in slight changes in pigmentation.
Hair color can range from very white to brown. People of African or Asian descent who have albinism may have hair color that’s yellow, reddish, or brown. Hair color may also darken by early adulthood or stain from exposure to normal minerals in water and the environment, and appear darker with age.
Eyelashes and eyebrows are often pale. Eye color can range from very light blue to brown and may change with age.
The lack of pigment in the colored part of the eyes (irises) makes the irises somewhat translucent. This means that the irises can’t completely block light from entering the eye. Because of this, very light-colored eyes may appear red in some lighting.
Vision impairment is a key feature of all types of albinism. Eye problems and issues may include:
The rapid, involuntary back-and-forth movement of the eyes (nystagmus)
Head movements, such as bobbing or tilting the head, to try to reduce the involuntary eye movements and see better
The inability of both eyes to stay directed at the same point or to move in unison (strabismus)
Extreme nearsightedness or farsightedness
Sensitivity to light (photophobia)
Abnormal curvature of the front surface of the eye or the lens inside the eye (astigmatism), which causes blurred vision
Abnormal development of the retina, resulting in reduced vision
Nerve signals from the retina to the brain that doesn’t follow the usual nerve pathways (misrouting of the optic nerve)
Poor depth perception
Legal blindness (vision less than 20/200) or complete blindness
When to see a doctor
At your child’s birth, if the doctor notices a lack of pigment in hair or skin that affects the eyelashes and eyebrows, the doctor will likely order an eye exam and closely follow any changes in your child’s pigmentation and vision.
If you observe signs of albinism in your baby, talk to your doctor.
Contact your doctor if your child with albinism experiences frequent nosebleeds, easy bruising, or chronic infections. These signs and symptoms may indicate the presence of Hermansky-Pudlak syndrome or Chediak-Higashi syndrome, which are rare but serious disorders that include albinism.
Causes of Albinism treatment
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 (OCA), the most common type, means a person inherited two copies of a mutated gene — one from each parent (autosomal recessive inheritance). It’s the result of a mutation in one of seven genes, labeled from OCA1 to OCA7. 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.
Albinism can include skin and eye complications as well as social and emotional challenges.
Problems with vision can impact learning, employment, and the ability to drive.
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 hurt people with the condition.
People with albinism may experience bullying, teasing, or probing questions about their appearance, eyewear, or visual aid devices. They usually look very different from members of their own families or ethnic groups, so they may feel like outsiders or be treated as outsiders. These experiences may contribute to social isolation, poor self-esteem, and stress.
Using the term “person with albinism” is preferred to avoid the stigma of other terms.
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. He or she can also explain the available tests.
