Abstract:
Comparative mapping of Ateles paniscus chamek and man indicated that four human 3p markers are syntenic in this karyotypically rearranged neotropical primate. The evolutionary conservation of this gene cluster includes three adjacent human shortest regions of overlap (SROs): 3p21.1 (ACY1), 3p21.3-->p21.2 (CACNA1D), and 3p21.3 (ZNF64). A fourth syntenic marker (ATP2B2), at a more distal human SRO (3p26-->p25), indicated that human 3pter-->p14 is evolutionarily conserved in Ateles chromosome 3 (APC 3). Conversely, allocations of two human 3q markers (AGTR1 and IL12A) clearly excluded APC 3. Finally, allocation of the major histocompatibility complex class I genes further confirmed human 6p-6q dissociations in Ateles.
