Description : Oculocutaneous albinism (OCA) is a heterogeneous autosomal recessive disorder, with
a worldwide prevalence of approximately 1:17,000. It manifests as a reduction or complete
loss of melanin in the skin, hair, and eyes, often accompanied by eye symptoms such
as photophobia, strabismus, moderate to severe visual impairment, and nystagmus (summary
by Wei et al., 2013). For a discussion of genetic heterogeneity of oculocutaneous
albinism, see OCA1 (203100). For a general phenotypic description and a discussion
of genetic heterogeneity of variation in skin, hair, and eye pigmentation, see;
