At a glance

A heterogeneous group of inherited diseases targeting the melanin pigmentary system.

Classification

(Note: Unfortunately, there is no universally accepted classification and the names may differ depending on the source. Particularly for Oculocutaneous Albinism (OCA) the names listed under “Synonyms” do not consistently match with the “Type,” so we recommend using the “Types” rather than the “Synonyms,” except for Hermansky-Pudlak and Chediak-Higashi Syndrome, which are well-established names. In contrast, for Ocular Albinism (OA), the use the “Synonyms” rather than the “Type” seems more consistent.)
