C3HeB/FeJ-Myo6Mhdatlc/IegWtsiCnbc
Status | Available to order |
EMMA ID | EM:05018 |
International strain name | C3HeB/FeJ-Myo6Mhdatlc/IegWtsiCnbc |
Alternative name | Tailchaser |
Strain type | Induced Mutant Strains : Chemically-induced |
Allele/Transgene symbol | Myo6Mhdatlc |
Gene/Transgene symbol | Myo6 |
Information from provider
Provider | Karen Steel |
Provider affiliation | Wellcome Trust Sanger Institute |
Additional owner | Helmholtz Zentrum Muenchen carried out the mutagenesis and discovered the head-bobbing. |
Genetic information | Sequencing of cDNA extracted and amplified from heterozygous brains revealed a c.G694T transversion in a region that corresponds to exon 6 of the gene. This mutation is predicted to result in an aspartic acid to tyrosine amino acid substitution at the highly conserved position 179 of the encoded protein. |
Phenotypic information | Tlc/+ mutants display classic behavioural symptoms of a vestibular dysfunction, including head-shaking and circling. Behavioural testing of ageing mice revealed a gradual deterioration of both hearing and balance function, associated with hair bundle defects of sensory hair cells. Homozygotes are more severely affected. |
Breeding history | Originated from ENU mutagenesis programme in Munich on a C3HeB/FeJ background and maintained on the same background within a closed colony or backcrossed to C3HeB/FeJ ever since. |
