Oculocutaneous albinism, immunodeficiency, hematological disorders, and minor anomalies: a new autosomal recessive syndrome?
We report on 2 related children, a boy and a girl, from a large Turkish clan. Their parents are both first cousins and have several common ancestors. Both children have tyrosinase-positive oculocutaneous albinism, recurrent bacterial infections, granulocytopenia, intermittent thrombopenia, and microcephaly, a protruding midface, rough and projecting hair, and mild mental retardation. Chromosomes are normal. Metabolic disorders were excluded. None of 14 well-known types of albinism, including Hermansky-Pudlak syndrome and Chediak-Higashi syndrome, nor any other genetic syndrome, characterizes our patients sufficiently. Thus, this combination of symptoms is considered a new autosomal recessive syndrome.
