Usp14	visible phenotype
D18Umi2	PCR amplified length variant
Lama3	Southern analysis	MN97

Notes

• Reference
  Authors use Tg9257 for locus symbol Tg.9257.
• Experiment
  The ataxia mutation arose on the kreisler strain and has been maintained as a congenic strain by backcrossing C57BL/6J for more than 40 years. Only affected ax/ax backcross progeny were typed.Offspring types indicate alleles inherited from F1 parent.
