mortality/aging
|
• at weaning, hemizygous male pups are present at the expected Mendelian number/ratio among progeny of crosses between heterozygous female and hemizygous or wild-type male mice
|
reproductive system
|
• male mice hemizygous for this mutation exhibit normal fertility
|
hearing/vestibular/ear
|
• hemizygous mutant male mice do not exhibit behaviors indicating vestibular dysfunction, e.g., circling or head bobbing/shaking
• the ABR thresholds of hemizygous mutant males do not differ significantly from those of control heterozygous and wild-type female mice, averaging 29 dB vs. 28 dB and 29 dB, respectively
• fixed, paint-filled inner ear structures of E15.5 hemizygous male embryos exhibit no gross morphological abnormalities
|
behavior/neurological
|
• hemizygous mutant male mice do not exhibit behaviors indicating vestibular dysfunction, e.g., circling or head bobbing/shaking
