New gene assignments in the baboon and new chromosome homoeologies with man.

Eight new gene assignments were demonstrated in the baboon (Papio papio, PPA) by cosegregation analysis of twelve hybrid clones obtained by fusion between PPA fibroblasts and a mouse cell line deficient in thymidine kinase. The following markers and syntenic groups were assigned: SOD1 to PPA3, GLO-ME1 to PPA-4, PGM2 to PPA5, CKBB-SORD to PPA7, LDHB to PPA11 and LDHA to PPA14. These localizations are in agreement wit hthe following homoeologies with the human karyotype: PPA3-HSA21, PPA4-HSA6, PPA5-HSA4, PPA7-HSA14 and 15, PPA11-HSA12, PPA14-HSA11.
