Gene assignment in the spider monkey (Ateles paniscus chamek-APC): APE-MYH7 to 2q; AR-GLA-F8C to the X chromosome

Comparative gene assignment between the spider monkey species Ateles panisc us chamek (APC) and man (HSA) showed conserved syntenic associations despit e extensive karyotypic rearrangement between species, Two HSA 14q genes wer e allocated to APC 2q, being syntenic to other HSA 14q and HSA 15q markers previously assigned to APC 2q, and to HSA 12q genes previously assigned to APC 2p, These findings were consistent with A, geoffroyi chromosome paintin g with human whole-chromosome probes, indicating that the genus Ateles is k aryotypically very rearranged. On the other hand, three human X-linked mark ers were assigned to the Ateles X chromosome, indicating that this chromoso me is evolutionary stable.
