Molecular assay reagents intended to identify deletions in the oculocutaneous albinism II (OCA2) gene, located in 15q11.2-q12, these genes are involved in producing a pigment called melanin, which is the substance that gives skin, hair, and eyes their color. When associated with Angelman\'s and Prader-Willi syndromes, clinical effects are a result of the deletion of one copy of OCA2 and a mutation in the other copy of OCA2.
