SLC45A2 and oculocutaneous albinism: Despite these noted limitations, our screen uncovered many genes that are known to regulate steps of melanosome maturation and whose functional loss leads to oculocutaneous albinisms (OCAs) and ocular albinism (OA) syndromes in humans, such as TYR (OCA1), OCA2, SLC45A2 (OCA4), SLC24A5 (OCA6), LRMDA (OCA7), DCT (OCA8), and GPR143 (OA).
