![]() This form is phenotypically expressed by a lack of retinal and integumentary melanin, indicating integumentary defects in the retinal melanophores (Muto et al., 2012). Complete (“real”) albinism refers to the total absence of integumentary and retinal pigmentation (Sandoval-Castillo et al., 2006). Distinct forms of albinism have been defined, all characterized by a normal number of melanocytes (Rees, 2003) accompanied with varying degrees of reduced melanin production. 1 out of 17 000 newborns (Montoliu and Kelsh, 2014).Īlbinism refers to the absence of pigmentation in an organism (Uieda, 2000). ![]() Among humans, the condition occurs in ca. ![]() Cabrera (1897) also reported on an individual that he identified as that species (based on coloration) that had just died in the Madrid Zoo. Partial albinism (“leucism,” see below), was responsible for the recognition of several species of primates: Lesson (1831, plate XXXII) named Troglodytes leucoprymnus, as a distinct species of chimpanzee ( now known as Pan troglodytes) based on a partially leucistic individual. The other report corresponded to a captive individual in Trivandrum Zoo, South India in 1936. One macaque was tied up with a chain to a tree outside a house in Goa, India. (2012) examined the phenomenon in Macaca sp., and noted that only two records of complete albinism had been reported in the literature for the Bonnet macaque, Macaca radiata (Mahabal et al., 2012). (2013) compiled all published cases of anomalous pigmentation reported in Neotropical mammals, undertaking a comprehensive review of peer reviewed articles between 19: they found no records of albinism in Neotropical Primates, but in numerous cases in other Orders of mammals. Palabras clave: Coloración del pelo, Conservación, Desorden genético, Leucismo, Mamíferos, Neotrópico.Īlbinism has been observed in numerous vertebrate species (Mora, 1990 Abreu et al., 2013) but its occurrence in the wild, particularly in Primates, is rare (Mahabal et al., 2012 Abreu et al., 2013). El caso de un mono araña albino en el este de Honduras podría resultar de un aumento de la consanguinidad. Los órganos y nervios sensoriales se ven particularmente afectados por estos trastornos debido al origen común de los melanocitos y los neurocitos en la cresta neural. En mamíferos, los trastornos de color del pelaje son el resultado de efectos pleiotrópicos. ![]() Si bien normalmente poco frecuente, la incidencia de este fenómeno en poblaciones silvestres puede aumentar debido a estrés ambiental, cual puede ser endogamia en poblaciones aisladas. El albinismo es una condición genética presentada en numerosas especies de vertebrados. Presentamos el primer caso de albinismo completo para el mono araña centroamericano (Ateles geoffroyi), una hembra juvenil del este de Honduras. Keywords: Coat color, Conservation, Genetic disorder, Leucism, Mammals, Neotropic. The instance of an albino spider monkey from eastern Honduras might result from increased inbreeding. Sensory organs and nerves are particularly affected by these disorders because of the shared origin of melanocytes and neurocytes in the neural crest. Coat color disorders result from pleiotropic effects in mammals. Although normally infrequent, the incidence of albinism in populations may change as a result of environmental stress, including inbreeding in isolated populations. Albinism is a genetic condition reported in numerous vertebrate species. We report the first case of complete albinism for the Central American spider monkey ( Ateles geoffroyi), a juvenile female from eastern Honduras.
