==Overview==
==Overview==
[[Albinism]] is a defect of [[melanin]] production that results in little or no color ([[pigment]]) in the skin, hair, and eyes.
[[Albinism]] is an inherited disease which is caused by defective [[melanin]] production. Melanin gives color to [[skin]], [[hair]], and [[eyes]].


==What are the symptoms of Albinism?==
==What are the symptoms of Albinism?==
A person with [[albinism]] will have one of the following symptoms:
Symptoms of [[albinism]] include both dermal and eye features:


* Absence of color in the hair, skin, or [[iris]] of the eye
* White or hypo-pigmented [[hair]]
* Lighter-than-normal skin and hair
* White or hypo-pigmented [[eyelashes]]
* Patchy, missing skin color
* White or hypo-pigmented [[skin]]
 
* [[Photophobia]]  
Many forms of albinism are associated with the following symptoms:
* Decreased [[visual acuity]]
 
* Pink or hypopigmented [[eyes]]
* Crossed eyes ([[strabismus]])
* [[Strabismus]]
* Light sensitivity ([[photophobia]])
* Rapid eye movements ([[nystagmus]])
* Vision problems, or functional [[blind]]ness


==What causes Albinism?==
==What causes Albinism?==
Albinism occurs when one of several genetic defects makes the body unable to produce or distribute melanin, a natural substance that gives color to your hair, skin, and iris of the eye.
[[Albinism]] is caused by [[mutation]] of [[genes]] that lead to defect in [[melanin]] synthesis. This [[mutation]] is inherited through the family.
 
The defects may be passed down through families.


===Types of albinism===
===Types of albinism===
There are two main types of albinism:
Types of [[albinism]] include:
 
* [[Oculocutaneous albinism]]; causes white or [[hypopigmentation]] of [[skin]], [[hair]], and [[eyes]]. The [[hypopigmentaion]] is usually seen when patients are compared to other family members
* Type 1 albinism is caused by defects that affect production of the pigment, [[melanin]].
* [[Hermansky-Pudlak syndrome]]; causes white or [[hypopigmentation]] of [[skin]], [[hair]], and [[eyes]] along with [[bleeding]] and [[lung]] problems
* Type 2 albinism is due to a defect in the "P" [[gene]]. People with this type have slight coloring at birth.
* [[Chediak-Higashi syndrome]];  Causes white or [[hypopigmentation]] of [[skin]], [[hair]], and [[eyes]]. It increases susceptibility to [[infection]] along with [[nerve]] defects and [[bleeding]] problems
 
* [[Ocular albinism]]; causes [[hypopigmentation]] of [[eyes]], [[nystagmus]], [[strabismus]], decreased [[visual acuity]], and [[photophobia]]
The most severe form of albinism is called oculocutaneous albinism. People with this type of albinism have white or pink hair, skin, and iris color, as well as vision problems.
 
Another type of albinism, called [[ocular albinism]] type 1 (OA1), affects only the eyes. The person's skin and eye colors are usually in the normal range. However, an eye exam will show that there is no coloring in the back of the eye ([[retina]]).
 
[[Hermansky-Pudlak syndrome]] (HPS) is a form of albinism caused by a single gene. It can occur with a bleeding disorder, as well as with [[lung]] and [[bowel]] diseases.
 
===Localized albinism===
Other complex diseases may lead to loss of coloring in only a certain area (localized albinism). These conditions include:
 
* [[Chediak-Higashi syndrome]] (lack of coloring all over the skin, but not complete)
* [[Tuberous sclerosis]] (small areas without skin coloring )
* [[Waardenburg syndrome]] (often a lock of hair that grows on the forehead, or no coloring in one or both irises)


==Who is at highest risk?==
==Who is at highest risk?==
Since albinism is an inherited condition, you are at an increased risk if you have a family history of albinism.<ref>http://www.healthline.com/adamcontent/albinism#causesincidenceandriskfactors</ref>
Individuals with familial history of [[albinism]] are at risk of [[albinism]]


==When to seek urgent medical care?==
==When to seek urgent medical care?==
Call your health care provider if you have albinism or symptoms such as light sensitivity that cause discomfort. Also call if you notice any skin changes that might be an early sign of [[skin cancer]].
* If you notice [[skin]] changes, they might be possible developing [[skin cancer]]
* If you notice a change in your vision or light sensitivity


==Diagnosis==
==Diagnosis==
[[Genetic testing]] offers the most accurate way to diagnose albinism. Such testing is helpful if you have a family history of albinism. It is also useful for certain groups of people who are known to get the disease.
[[Genetic testing]] is the most definite test for diagnosis. Additionally, [[ophthalmology]] examination is considered for evaluation of [[eye]] features.
 
Your doctor may also diagnose the condition based on the appearance of your skin, hair, and eyes. An ophthalmologist should perform a [[electroretinogram]] test, which can reveal vision problems related to albinism. A visual evoked potentials test can be very useful when the diagnosis is uncertain.


==Treatment options==
==Treatment options==
The goal of treatment is to relieve symptoms and depends on the severity of the disorder.
The treatment options include:
 
Treatment involves protecting the skin and eyes from the sun:
 
* Reduce [[sunburn]] risk by avoiding the sun, using sunscreen, and covering up completely with clothing when exposed to the sun.
* Sunscreen should have a high [[sun protection factor]] (SPF).
* Sunglasses (UV protected) may relieve [[light sensitivity]].


Glasses are often prescribed to correct vision problems and eye position. Eye muscle surgery is sometimes recommended to correct abnormal eye movements ([[nystagmus]]).
* Avoidance of prolonged sun exposure
* Sunglasses with [[UV]] protection for [[light sensitivity]]
* Upon sun exposure, application of [[sunscreen]] with at least SPF 30+ every 2 hours is recommended
* Glasses to correct vision problems and eye position
* [[Eye]] [[muscle]] [[surgery]] for severe [[strabismus]]

==Prevention of Albinism==
==Prevention of Albinism==
Because albinism is inherited, genetic counseling is important. People with a family history of albinism or [[hypopigmentation]] should consider genetic counseling.
People with a family history of [[albinism]] should consider genetic counseling before [[pregnancy]]


==What to expect (Outlook/Prognosis)?==
==What to expect (Outlook/Prognosis)?==
Albinism does not usually affect lifespan. [[Hermansky-Pudlak syndrome]] can, however, shorten lifespan due to [[lung disease]] or [[bleeding]] problems.
Patient with [[albinism]] has normal [[life expectancy]]
 
People with albinism may be limited in their activities because they can't tolerate the sun.
