International strain name | STOCK Myo7ash1-6J/WtsiH |
Alternative name | Moonwalker |
Strain type | Spontaneous |
Allele/Transgene symbol | Myo7ash1-6J |
Gene/Transgene symbol | Myo7a |
Information from provider
Provider | Karen Steel |
Provider affiliation | Wellcome Trust Sanger Institute |
Additional owner | Originally picked up by Verity Letts and Ken Johnson at the Jackson Labotatory. |
Genetic information | A G-to-C transversion mutation is predicted to result in an arginine to proline change at position 241 in the encoded Myo7a protein. |
Phenotypic information | This is a spontaneous mutation affecting the sensory hair cells of the inner ear and leading to deafness and balance defects with circling and head bobbing. |
Breeding history | The mutation originated on a C57BLKS/J genetic background and was outcrossed and intercrossed with AKR/J for mapping. It was then maintained on the same background within a closed colony for over fifteen years. These embryos have been produced by mating homozygous males with CBA/Ca females. |
