Balance, coordination, and traction in wild-type, heterozygous, and homozygous mutant mice

Genotype	Rod-walking test		Wire-hanging test
Genotype	Time (sec, mean ± SEM)^2-a	n	Accomplished^2-b/number of tests^2-c	n
Wild-type mice	43.85 ± 22.43	4	4/6	3
Heterozygotes	78.92 ± 47.29	11	NT
Homozygotes	50.49 ± 21.90	6	10/12	6

NT, Not tested.
↵F2-a After a training trial, the time of the second trial was recorded.
↵F2-b Mice that were hanging on a wire with their paws for >20 sec were counted as accomplished.
↵F2-c Each mouse was tested twice.
