Gene assignments and syntenic groups in the sacred baboon (Papio hamadryas).

Eighteen genes were assigned to chromosomes in the sacred baboon, Papio hamadryas, by their concordant segregation with the chromosomes in a set of baboon X Chinese hamster somatic cell hybrids. ACY1 was assigned to P. hamadryas chromosome 2 (PHA 2); SOD1 and MDH2 to PHA 3; ME1 and SOD2 to PHA 4; NP, MPI, PKM2, and HEXA to PHA 7; PP to PHA 9; ADA and ITPA to PHA 10; LDHB and TPI1 to PHA 11; MDH1 to PHA 13; ESD to PHA 17; and GPI and PEPD to PHA 20. Regional assignments were possible for ACY1 (PHA 2pter----q1) and MDH2 and SOD1 (PHA 3p). Five other independently segregating markers or syntenic groups (PGD, PGM1; and PEPC; PGM2 and PEPS; IDH1; LDHA and ACP2; and GSR) were also identified. Gene assignments and syntenic groups described in P. hamadryas are compared to those found in P. papio, the rhesus monkey, and man. A possible primate model for human lymphoid disease is discussed.
