title: Tyrosinase positive albinism with familial 46,XY,t(2;4) (q31.2;q31.22) balanced translocation.
abstract: A subject with clinical and biochemical tyrosinase positive oculocutaneous albinism (OCA) also had a balanced translocation, 46,XY,t(2;4)(q31.2;q31.22). This observation provides evidence for a possible gene locus in the q31 region of chromosome 2 or 4.
