Assignment of TCF1, TGM1, CALM1, CKB, THBS1, B2M, and FES in Ateles paniscus chamek (Platyrrhini, Primates).

Regional assignment of five markers to chromosome 2 of Ateles paniscus chamek (APC) confirmed a syntenic association similar to human (HSA) 12q + 14q + 15q. TCF1 was allocated to a shortest region of overlap (SRO) in APC 2p and found to be syntenic to PEPB, while TGM1, CALM1, THBS1, and B2M were assigned to APC 2q, being syntenic to NP, HEXA, and MPI. Conversely, markers close to HSA 14qter (CKB) and HSA 15qter (FES-IDH2) were relocated to other Ateles syntenic groups. Karyotypic comparisons showed an evident homoeology between APC 2p and HSA 12q, whereas APC 2q was similar to an HSA 14qter::HSA 15qter fusion product.
