Cancer of the skin, in general, is believed to be rather uncommon in black persons. Collected reports from the US showed that, out of 357 skin cancer cases, 5 (1.4%) were expressly stated to be albinos. A Nigerian comparable series of 435 patients manifested 15 (3.4%) albinos. Therefore, it is hypothesized that albinism is a good model for studies on skin adaptation as it concerns albinos in US...

The present study reports spontaneous tyrosinase gene mutations identified in oculocutaneous albinos of three Japanese wild frog species, Pelophylax nigromaculatus, Glandirana rugosa and Fejervarya kawamurai. This represents the first molecular analyses of albinic phenotypes in frogs. Albinos of P. nigromaculatus collected from two different populations were found to suffer from frameshift muta...

Oculocutaneous albinism which is characterised by impaired melanin biosynthesis is the most common inherited pigmentary disorder of the skin and it is common among Blacks in sub-Saharan Africa. All albinos are at great risk of developing squamous cell carcinoma of sun-exposed skin, and Black albinos in sub-Saharan Africa are at about a 1000-fold higher risk of developing squamous cell carcinoma...

There is both anatomical and electrophysiological evidence that human albinos have abnormally crossed visual pathways. The present study examined some perceptual consequences of such pathways on the visual abilities of 12 oculocutaneous albinos and one ocular albino. Measurements were made of visual fields in all subjects. For seven subjects, contrast sensitivity functions were obtained for the...

Background: Albinos in Africa are at constant risk of developing skin cancer due to the damage caused by ultra-violet exposure. This study identifies the common skin conditions among albinos in Kenya as a country located along the equator.    Methods: In this descriptive study on albino patients who were admitted to Mbagathi District Hospital in Nairobi, Kenya the census method was...

The sex-linked gene for imperfect albinism (S*ALS) has been associated with slow early growth in some trials but not in others. Albino (59) and nonalbino (73) chicks were raised to 3 d of age to study early growth. At 3 d of age, plasma beta-hydroxybutyrate (beta-HBA) levels were measured and the chicks were euthanatized and dissected to measure liver, gall bladder, and yolk sac weights. Fatty ...
