Abstract:
Genetic distances between reeler (gene symbol rl) and the adjacent loci Pgy-1, Sor, and En-2 on proximal chromosome 5 were estimated using a backcross panel between rlOrl/rlOrl BALB/c and C57 mice. Pgy-1 and Sor are located approximately 7 cM away from and centromeric to reeler, whereas En-2 is located distally, approximately 8 cM from reeler. Backcrosses between rlOrl/rlOrl BALB/c and mice with the T31H translocation showed that the breakpoint is located less than 2 cM from reeler. Together with previous work, these observations suggest the following gene order: Cen-Sor/Pgy-1-rl-T31H-En-2-other loci.
