Oculocutaneous Albinism (OCA)
OCA affects the skin, hair, and eyes.                                      Who Is at Risk for Albinism?

Ocular Albinism (OA)                                                       Albinism is an inherited disorder that’s present at birth. Children are at

People with OA have normal hair, skin, and eye colouring, but have no
colouring in the retina (the back of the eye).                             Symptoms of Albinism

Hermansky-Pudlak Syndrome (HPS)                                            People with Albinism will have the following symptoms:
HPS is a rare form of Albinism that is due to a defect in one of eight     Ÿ an absence of colour in the hair, skin, or eyes
genes. It produces symptoms similar to OCA, and occurs with lung,          Ÿ lighter than normal colouring of the hair, skin, or eyes

Chediak-Higashi Syndrome                                                   Albinism occurs with vision problems, which may include:
