STRAIN INFORMATION


Family Identifier
NMF334
Synonym(s)
Grid2nmf334; Grid2ho-16J; C57BL/6J-Grid2ho-16J/J; JR#5447
Synopsis
Body tremor, trunk swaying, high lifting of hind limbs.
Gene Symbol
Grid2 (View MGI Record)
Gene
glutamate receptor, ionotropic, delta 2
Allele Symbol
Grid2nmf334 (View MGI Record)
Allele
neuroscience mutagenesis facility334
Abnormal Assay(s)
Assay: Overt movement/posture

   Domain(s): Visible Mutants ; Movement/Neuromuscular Function
Phenotype Description
The mutants show body tremor, with intermittent muscle spasms visible across the area of the lower back and hind limbs, and slight trunk swaying; hind limbs are lifted high during walking. This phenotype becomes visible at approximately 4 weeks of age (average 3.7+/-1.3 weeks of age; n=55); mutants breed and a colony can be maintained through normal breeding. A complementation test with Grid2ho-15J (JR#005344; homozygous x heterozygous mating) resulted in 7 affected mice in a total of 16 progeny and therefore demonstrates that nmf334 represents an allele of Grid2.   (View video)
Pathology Report
Standard pathology work-up on two mutants (24 days of age) revealed no abnormalities.
