“…In non-human primates, several cases of autosomal trisomies corresponding to human trisomies 21, 18, and 13 have been reported, such as chimpanzee trisomy 22 [Mc-Clure et al, 1969;Hirata et al, 2017], bonobo trisomy 17 [Lear et al, 2001], orangutan trisomy 22 [Andrle et al, 1979], baboon trisomies 17 and 18 [Howell et al, 2006;Moore et al, 2007], and night monkey trisomy 18 [Hirai et al, 2017]. In macaques, 2 cases homologous to human trisomy 18 [Swartz and Sackett, 1994;de Waal et al, 1996] and 3 cases homologous to human trisomy 13 [Vigfusson et al, 1986;Ward et al, 1994;Ruppenthal et al, 2004] have been reported. Cases of trisomy 17 in Macaca nemestrina as well as trisomy 18 in Macaca mulatta are likely to result in severe signs and multiple anomalies during development, even in mosaic individuals; however, cases of trisomy 17 in M. fascicularis do not show the severe trisomy 13 features seen in humans.…”
