What current research is being done on albinism?
A small pilot clinical study at the National Eye Institute (NEI) suggests that the drug nitisinone increases melanin production in some people with oculocutaneous albinism type 1B (OCA-1B), a rare genetic disease that causes pale skin and hair and poor vision.
What are some future albinism treatments?
Nitisinone, which is approved by the US Food and Drug Administration (FDA) for treating hereditary tyrosinemia type 1, elevates plasma tyrosine levels and increases eye and hair pigmentation. Nitisinone may soon be a potential treatment for people with ocular albinism.
Is there any gene therapy for albinism?
An effective therapy is unavailable for albinism at present. However, to fight OCA in the future, gene therapy can be used. Gene therapy can include use of such as retrovirus vectors, adenovirus vectors, and CRISPR/Cas9 system. Research results in animal models have shown remarkable advances.

What is the epidemiology of albinism?
An estimated 1 in 17,000 people have one of the types of albinism. Approximately 18,000 people in the United States have albinism. OCA 1 occurs in approximately 1 in 40,000 individuals in most populations. OCA 2 is the most common type of albinism and is especially frequent among African Americans and Africans.

What tests are done to diagnose albinism?
The most accurate way to diagnose albinism is through genetic testing to detect defective genes related to albinism. Less accurate ways of detecting albinism include an evaluation of symptoms by a doctor or an electroretinogram test.
Can albinism be detected during pregnancy?
KIE: Albinism, a recessive genetic condition, can be diagnosed by fetoscopy between the 16th and 20th weeks of pregnancy, in time for subsequent abortion.
How can albinism be prevented?
Albinism cannot be prevented, as it is an inherited (genetic) condition rather than an illness. Gene testing can be used to determine if a fetus has albinism.
Could albinism have been prevented?
Which type of albinism is most common?
The 2 main types of albinism are: oculocutaneous albinism (OCA) – the most common type, affecting the skin, hair and eyes. ocular albinism (OA) – a rarer type that mainly affects the eyes.
Which enzyme causes albinism?
Enzyme. The enzyme defect responsible for OCA1-type albinism is tyrosine 3-monooxygenase (tyrosinase), which synthesizes melanin from the amino acid tyrosine.
What genetic testing is done for albinism?
The most definitive test in determining the albinism type is genetic sequence analysis. Of course, the test is useful only for families with individuals who have albinism. The test cannot be used as a screening tool. Genetic sequence analysis can be used to determine if a fetus has albinism.
What are some interesting facts about albinism?
Potential Problems. Albinism is not in itself dangerous or a cause for concern,but it can lead to some secondary problems.
What are the statistics on albinism?
Albinism can occur in all ethnicities. The chances of being born with albinism are one in roughly 17,000. Males and females are affected equally. In Africa the rate of albinism is about 1 in 5,000. In Europe the rate is about 1 in 20,000 . The highest rate of albinism occurs in those with sub-Saharan African ancestry.
What are the treatment options for albinism?
Treatment generally includes: Eye care. This includes receiving an annual eye exam by an ophthalmologist and most likely wearing prescription corrective lenses. Although surgery is rarely part of treatment for eye problems related to albinism, your ophthalmologist may recommend surgery on optical muscles to minimize nystagmus.
What are the chances of having albinism?
About 1 in 70 people have a gene for albinism. Couples whom are each carriers of the recessive albinism gene have a 1 in 4 chance of producing a child with albinism.
