Cleft lip and palate associated with other malformations in a neotropical primate (Saimiri ustus).
Cleft lip (with or without cleft palate) has been documented in several species of nonhuman primates, which in general are susceptible at similar doses and stages of gestation to the same teratogens as humans. Cleft lip can be unilateral or bilateral, isolated, syndromic, familial, or genetic. Here we report the first case of syndromic cleft lip and palate in a male bare-eared squirrel monkey (Saimiri ustus). Associated with the orofacial clefts, the monkey manifested absence of bones, malformation of vertebrae L3, only 4 fingers in each hand, and shortening of tendons leading to inflection of the hands and fingers. Previous reports describing cleft lip and palate in other squirrel monkeys (Saimiri sciureus) in other breeding units have suggested consanguineous mating as a possible cause. Although the etiology in the case we present is unknown, we discuss factors associated with orofacial clefts in humans and various nonhuman primates.
