Facial dysplasia in wild chimpanzees.
At least 10% of the Sebitoli chimpanzee community of the Kibale National Park (Uganda) present a characteristic facial phenotype with flattened nose, reduced nostrils, and concave mid-face. Affected individuals do not present skin lesions, and also young infants are affected. We suggest, therefore, a congenital origin of this defect.
