Abstract In this study, we report on a Cameroonian family from the Ewondo ethnic group, presenting with three oculocutaneous albinism type 2 (OCA2) patients homozygous for the 2.7-kb deletion of the P gene. [nature.com]

In albinos however these cancers are known to present earlier [15-17]. [odermatol.com]

Metastasis workup was negative. Complete surgical excision, strict photoprotection and regular follow-up were advised. A timely recognition of this potentially aggressive neoplasm is the key to curative treatment. [e-ijd.org]

Treatment Treatment Options: There is no treatment for the basic disease but low vision aids may be helpful for some patients. Dark glasses provide comfort for photophobic individuals. The skin should be protected against sunburn. [disorders.eyes.arizona.edu]

There is no cure for vitiligo, but there are several treatments, including cosmetic cover-ups, corticosteroid creams, calcineurin inhibitors (Elidel cream, Protopic ointment) or ultraviolet light treatments. [webmd.com]

[…] tyrosine Genetics inheritance pattern autosomal recessive mutations type 1 chromosome 11 gene encoding tyrosinase type 2 chromosome 15 OCA2 gene encodes small molecule transporters involved in transport of tyrosinase Associated conditions skin cancer Prognosis [medbullets.com]

Complications Skin cancer, sunburn Reduced visual acuity Social stigma Prognosis Patients with albinism have a normal lifespan. An increased risk of skin cancer exists; however, this is curable. Patients may have children with no complications. [medcaretips.com]

The patient will continue to benefit from rehabilitative services in the United States, and the patient’s prognosis is positive as OCA is a stable condition. [coavision.org]

Prognosis Lifespan, development, intelligence, and fertility in patients with OCA are not different from unaffected patients. [eyewiki.aao.org]

Prognosis Growth, development and intellectual development in the child are normal. Vision is invariably severely impaired [ 2 ]. A spectrum of structure and function exists in albinism. [patient.info]

Etiology Biochemical pathway leading to melanin production. Note that Tyrosinase is essential for the first two steps of the pathway. [eyewiki.aao.org]

Epidemiology [ 2 ] About 1 in 70 people carry a gene for OCA. Approximately 1 in 17,000 people in Europe and the USA have one of the types of albinism, although in some parts of the world it is more common than this. [patient.info]

Pathophysiology of Albinism Melanin is a pigment in the skin that absorbs ultraviolet light from the sun, thereby preventing skin damage. The tanning of the skin normally on sun exposure is due to increased melanin pigment in the skin. [medcaretips.com]

Most of these mutations eliminated the activity of tyrosinase, preventing melanin production by melanocytes. These mutations cause a form of oculocutaneous albinism called type 1A (OCA1A). [ivami.com]
