A rare deafness characterized by the association of bilateral sensorineural hearing loss and white hair with scattered black tufts, as well as skin areas of hyper- and hypopigmentation. Additional reported features include global developmental delay and moderate intellectual disability, growth retardation, microcephaly, hypotonia, mild dysmorphic facial features (deeply set eyes, broad nasal bridge, slight bowing of the upper lip), retinal depigmentation, anomalies of the fingers and toes, and white matter abnormalities on brain imaging.

Researchers have identified multiple types of oculocutaneous albinism, which are distinguished by their specific skin, hair, and eye color changes, and by their genetic cause. Oculocutaneous albinism type 1 is characterized by white hair, very pale skin, and light-colored irises. Type 2 is typically less severe than type 1; the skin is usually pale and hair may be light yellow, blond, or light brown. Type 3 causes reddish-brown skin, ginger or red hair, and hazel or brown irises. Type 3 is often associated with milder vision abnormalities than the other forms of oculocutaneous albinism. Type 4 has signs and symptoms similar to those seen in people with type 2.\n\nOculocutaneous albinism also reduces pigmentation of the colored part of the eye (the iris) and the light-sensitive tissue at the back of the eye (the retina). People with this condition usually have vision problems such as reduced sharpness; rapid, involuntary eye movements (nystagmus); eyes that do not point in the same direction (strabismus); and increased sensitivity to light (photophobia).\n\nOculocutaneous albinism is a group of conditions that affect the color of (pigmentation) of the skin, hair, and eyes. Affected individuals typically have very fair skin and white or light-colored hair. Long-term sun exposure greatly increases the risk of skin damage and skin cancers, including an aggressive form of skin cancer called melanoma, in people with this condition. \n\nThere are several additional, rare types of oculocutaneous albinism.

Waardenburg syndrome type 2F (WS2F) is characterized by congenital or neonatal-onset sensorineural hearing loss and altered pigmentation of the iris, hair, and skin. Variable expressivity has been reported, even among patients with the same mutation (Ogawa et al., 2017; Vona et al., 2022). For a general phenotypic description and discussion of genetic heterogeneity of WS2, as well as a brief description of other clinical variants of Waardenburg syndrome (WS1, 193500; WS3, 148820; and WS4, 277580), see WS2A (193510).
