Both known genes are on the X chromosome. When the term "autosomal recessive ocular albinism" ("AROA") is used, it usually refers to mild variants of oculocutaneous albinism rather than ocular albinism, which is X-linked.
Also known as Nettleship-Falls syndrome, is the most common variety of ocular albinism. OA1 is usually associated with nystagmus, and difficult to otherwise detect in females; males show more readily observable symptoms.
