Strain Details

Type JAX® GEMM® Strain - Mutant Strain
Additional information on JAX® GEMM® Strains.
Type JAX® GEMM® Strain - Spontaneous Mutation
Specieslaboratory mouse
GenerationN14p

Strain Description
When mice homozygous for the twister spontaneous mutation (twt) are picked up by the tail, all affected mice tuck their heads. Homozygous mutant mice may show circling behavior or tilted heads and none can swim. These mice are deaf.

Strain Development
The twister mutation arose spontaneously in a Largemyd stock in 1977 at The Jackson Laboratory. An myd female from strain MYD/Le was outcrossed to a B6C3Fe-a/a hybrid male. The F1 offspring were intercrossed and at the F2 generation the first twister mutant appeared. The stock was then maintained by crossing to the hybrid B6C3Fe-a/a and intercrossing the next generation to produce the homozygote. Using this cross intercross system the stock was bred to N23 and cryopreserved in 1984 by mating homozygous (Otogtwt/Otogtwt) males at N13 to B6C3Fe-a/a F1 females.

Mammalian Phenotype Terms assigned by genotype

Otogtwt/Otogtwt

        involves: C3HeB/Fe * C57BL/6
  • behavior/neurological phenotype
  • abnormal pinna reflex (J:65390)
    • Preyer reflex is normal at 3-4 weeks of age but by 10-20 weeks of age, a weak Preyer reflex is seen in 5 of 7 mutants
  • abnormal placing response (J:65390)
    • as early as P4, mutants exhibit head and trunk curling when picked up by their tail
  • absent startle reflex (J:65390)
    • none of the mutants at 10-20 weeks of age exhibit a body startle reflex
  • hyperactivity (J:65390)
    • some mutants show hyperactivity
  • impaired balance (J:65390)
    • the abnormal placing response, righting response, and response in the elevated platform test appear to result from impaired balance
    • circling (J:65390)
      • some mutants exhibit circling behavior
      • all mutants adopt a swimming, circling style with tilted head but do not sink
    • head tilt (J:65390)
      • after 2 weeks of age, most mutants have a tilted head on one side
      • all mutants adopt a swimming, circling style with tilted head but do not sink

  • abnormal ear physiology (J:65390)
    • abnormal pinna reflex (J:65390)
      • Preyer reflex is normal at 3-4 weeks of age but by 10-20 weeks of age, a weak Preyer reflex is seen in 5 of 7 mutants

Gene & Allele Details

Allele Symbol Otogtwt
Allele Name twister
Common Name(s) twt;
Strain of Origin(C57BL/6 x C3HeB/Fe-Largemyd)F1
Gene Symbol and Name Otog, otogelin
Chromosome 7
Gene Common Name(s) FLJ46346; OTGN; mlemp; twister; twt;
Molecular Note Complementation studies established that twister is an allele of Otog. Southern blot analysis of the mutant gene suggested that a point mutation or a small discrete rearrangement in the 3' region that created a new BstEII site was responsible for the mutant phenotype. [J:65390]

Supply Details

Standard SupplyRepository-Cryopreserved. Must Be Recovered. Please refer to the Supply Notes for further information.
Supply Notes Cryorecovery - Standard.
The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery.

Cryorecovery to establish a Dedicated Supply for greater quantities of mice.
One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services: Tel: 1-800-422-6423 or 1-207-288-5845; Email: jaxservices@jax.org.
Genomic DNA is available for this strain from the Mouse DNA Resource.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
