Stock number: 012625
Research areas: Metabolism Research, Neurobiology Research

Description

Mice both homozygous for the wblo mutation and homozygous or hemizyogus for the Gla^tm1Kul mutation develop a wobbly gait by approximately 5 weeks of age that decreases in severity with age.

Detailed description

Mice both homozygous for the wblo mutation and homozygous or hemizyogus for the Gla^tm1Kul mutation develop a wobbly gait by approximately 5 weeks of age that decreases in severity with age.

Development

The wblo mutation arose spontaneously in the homozyogus strain B6;129-Gla^tm1Kul/J. One backcross to C57BL/6J was done and then the offspring were sibling intercrossed. The resulting strain is still homozygous for the X-linked Gla^tm1Kul mutation and maintained segregating for the recessive wblo mutation.

Allele

Symbol: Itpr1^wblo
Name: wobbly locomotion
MGI accession ID: MGI:4437432
Generation method: Spontaneous
Marker symbol: Itpr1
Marker name: inositol 1,4,5-trisphosphate receptor 1
Chromosome: 6
Strain of origin: B6;129-Gla^tm1Kul/J
Molecular note: This spontaneous mutation was identified at The Jackson Laboratory. The molecular lesion is a G-to-A mutation at coding nucleotide 1166 of the cDNA (NM_010585) which alters an arginine to a histidine at position 389 of the encoded protein (p.R389H).
