Covers all situations in which the lack of pigment is generalized, and therefore affects skin, hair and eyes. There are two genetically distinct forms: OCA1 and OCA2.
Patients with OCA1 have a lack of pigment far more severe than those with OCA2. However, there are moderate forms of OCA1 which can sometimes be indistinguishable from OCA2.
The transmission of both forms is autosomal recessive and the risk of recurrence is 1 affected child in 4 for each pregnancy.
