Abstract: To the Editor:Oculocutaneous albinism (OCA) is an autosomal recessive disorder caused by a group of mutations related to the regulation of melanin synthesis and melanosome biogenesis.The prevalence of OCA worldwide is approximately 1 in 17,000.[1] Other than symptomatic treatment,there is no effective treatment for albinism.Due to the variability in clinical phenotypes,it is difficult to classify sub-types simply by clinical features;therefore,molecular and genetic analyses are the most reliable methods for confirming diagnosis,carrier screening,and pre-natal diagnosis.
