Genetic information | This is a missense variant in Tbx1, g.16:18584128C>T, which results in an amino acid change of p.(Asp212Asn) (ENSMUST00000232335). |
Phenotypic information | Homozygous:Mice homozygous for the twitch (ttch) allele exhibited circling and head bobbing behaviour and had no auditory response to any stimulus up to 95dB SPL, associated with a malformed inner ear.Heterozygous:No obvious defect |
Breeding history | These mutants were maintained for several years by intercrossing within a closed colony on the same C57BL/6N background that the mutation arose on. The original colony that showed this spontaneous mutation carried a targeted mutation of Arpc3 (Arpc3tm1a(EUCOMM)Wtsi) and this may still be present in the background. We also found two further spontaneous mutations that may still be present in the background of the cryopreserved mice: a 27bp in-frame deletion in the Kmt2d gene, g.15:98863687_98863713del mutation, resulting in a loss of 9 amino acids (ENSMUST00000023741, p.586-594del); and a missense mutation in the gene Muc13, g.16:33807881Cm1Wtsi or Muc3sp). The Arpc3, Kmt2d and Muc3 mutations did not lead to any obvious phenotypes. |
