  • Externally Sourced Definition: Type: Inbred Strain Type: Segregating Inbred TJL Mating System: Sibling x Sibling (Female x Male) Species: laboratory mouse H2 Haplotype: b Appearance light-bellied agouti chinchilla Related Genotype: Aw/Aw Tyrc-ch/Tyrc-ch Important Note This strain is homozygous for Cdh23ahl, the age related hearing loss 1 mutation, which on this background results in progressive hearing loss with onset after 10 months of age. Strain Description Historically, the 129 inbred mice are known for the high incidence of spontaneous testicular teratomas, though the incidence differs between substrains. (1-3% in 129 parental substrains; 30% in teratoma substrains.) More recently 129 mice are widely used in the production of targeted mutations due to the availability of multiple embryonic stem cell lines derived from them. There is major genetic variation within the 129 "family", which has led to an update of the nomenclature and a division of the substrains into three major groups: parental substrains (129P), steel substrains (129S) and "teratoma" substrains (129T). Investigators using 129 substrains for targeted mutagenesis should be careful in the selection of the appropriate 129 substrain to match the embryonic stem cell line. For a complete history of the numerous 129 substrains, see Simpson, et al., 1997.
