Acanthosis nigricans is a brown to black, poorly defined, velvety hyperpigmentation of the skin. It is usually found in body folds, such as the posterior and lateral folds of the neck, the armpits, groin, navel, forehead and other areas.
Understanding Albinism and its challenges to people with albinism This is called Ocular albinism (OA), and is much less common. Most cases are ocured in males.

Ocular albinism Type 1 (Nettleship-Falls syndrome), caused by mutation in GPR143 gene, is the most common kind of ocular albinism and is generally associated with rapid involuntary movement of the eyes (nystagmus).; Ocular albinism Type 2, also known as Aland Island eye disease or Forsius-Eriksson syndrome (pp.447), is caused by mutation in CACNA1F gene (pp. 2498). Download PDF Copy; By HH Patel, M.Pharm. Reviewed by Dr. Liji Thomas, MD. Two major types of albinism have been reported, which include ocular albinism (OA) and oculo-cutaneous albinism (OCA Ocular albinism, first described by Nettleship 1 in 1887, is a condition in which only the eye is lacking in pigmentation and the rest of the body is normally pigmented. It is a classic example of a disease transmitted as a sex-linked recessive. In typical ocular albinism there is a pendular nystagmus, a diaphanous iris which transilluminates, and a fundus which is lacking in pigmentation so Download PDF Info Publication number Nitisinone for the treatment of oculocutaneous / ocular albinism and to increase pigmentation. Background of the invention. Albinism (also called acromia, acromasia or acromatosis) is a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair and eyes due to the X-linked ocular albinism (OA1) is an X-linked inherited disease characterized by hypopigmentation of the fundus and nystagmus. Our study performed mutation analysis of the G protein-coupled Ocular albinism type I (OA1), or X-linked ocular albinism, is the most common form of ocular albinism. Ocular albinism is a genetic disorder characterized by vision abnormalities in affected males. Vision deficits are present at birth and do not become more severe over time. Affected individuals have normal skin and hair pigmentation.
Ocular albinism (OA1) is caused by a change in the GPR143 gene that plays a signaling role that is especially important to pigmentation in the eye. OA1 follows.
Oculocutaneous albinism type 2 (OCA2) is characterized by hypopigmentation of the skin and hair and the characteristic ocular changes found in all types of albinism, including nystagmus; reduced iris pigment with iris translucency; reduced retinal pigment with visualization of the choroidal blood vessels on ophthalmoscopic examination; foveal hypoplasia associated with reduction in visual Oculocutaneous albinism (OCA) is a heterogenous group of autosomal recessive disorders affecting melanin synthesis, characterised by congenital hypopigmentation of the skin, hair, and eyes. Reduced visual acuity, photophobia, iris transillumination, foveal hypoplasia, nystagmus, and an abnormal decussation of nerve fibres at the optic chiasm are common features.1 Ocular albinism (OA) shares Oculocutaneous albinism (OCA) is a genetically heterogeneous disorder characterised by abnormally low amounts of melanin in the eyes, skin, and hair. In addition to hypopigmentation of the skin and eyes, OCA patients have ocular manifestations including nystagmus, foveal hypoplasia with reduced visual acuity, and strabismus.1 Several subtypes of OCA exist. ALBINISM Other Common Names Hypopigmentation Causes/Etiology Most types of albinism are inherited when a child receives the albinism gene from both parents. There is an exception with one type of ocular albinism which is passed on from mothers to sons. Albinism occurs when there is a mutation in one of several genes.

Oculocutaneous albinism is a form of albinism involving the eyes (oculo-), the skin (-cutaneous), and according to some definitions, the hair. Overall, an estimated 1 in 20,000 people worldwide are born with oculocutaneous albinism.

Albinism is no longer a clinical diagnosis. The past classification of albinism was predicated on phenotypic expression, but now molecular biology has defined the condition more accurately. With recent advances in molecular research, it is possible to diagnose many of the various albinism conditions on the basis of genetic causation.

Oculocutaneous albinism type 2 (OCA2), an autosomal recessive mutation of the OCA2 gene on chromosome 15, results in ocular and dermatologic manifestations. In primary care, nurse practitioners must detect the condition, refer to specialists, provide psychosocial support, refer to community resources, and coordinate care for children with this disorder.
