Myo7ash1-8J homozygous mice circle and bob their heads; heterozygotes are behaviorally normal. Homozygotes of both sexes are viable and fertile (Samples 2000). The hearing of Myo7ash1-8J mutants has not been examined. However, other Myo7a mutations, whose behavioral phenotypes are virtually identical to that of Myo7ash1-J, are associated with deafness.Mutations in the human ortholog of Myo7a, MYO7A, have been characterized in pedigrees of patients having Usher syndrome type 1 (USH1), an autosomal recessive disorder characterized by profound deafness, vestibular dysfunction and progressive retinitis pigmentosa (Weil et al., 1995; Weston et al., 1996; Adato et al., 1997; Levy et al., 1997; Liu et al., 1998; Espinos et al., 1998; Cuevas et al., 1998, 1999; Janecke et al., 1999). MYO7A mutations have also been identified in patients with autosomal dominant non-syndromic deafness (Liu et al., 1997) and autosomal recessive isolated deafness (Liu et al., 1997; Weil et al., 1997).
Strain Development
The Myo7ash1-8J mutation occurred spontaneously on B6,SJL-TgN(c177lacZ)226Bri while the latter was being bred in the Importation facility at The Jackson Laboratory. Myo7ash1-8J was transferred to the C57BL/6J background by seven rounds of backcross-intercross breeding; homozygous males produced by mating heterozygous sibs were bred to C57BL/6J females to yield the next generation of heterozygotes. The colony was genotyped for TgN(c177lacZ)226Bri in March, 2000 and verified free of the transgene.

| General Note |
Genetic Background:The 266Bri stock on which Myo7ash1-8J arose was homozygous for a lacZ transgene. The mutation was not the result of the transgene integration, as not all animals exhibited the neurological phenotype. | ||
| Molecular Note | This phenotypic mutant was shown to be an allelic to Myo7ash1 by complementation testing. [MGI Ref ID J:77937] | ||

| 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. |
