Strain of Origin:  129P2/OlaHsd
Allele Type:    Targeted
Mutation:    Insertion
Mutation detailsThe human mutation R192Q was knocked in to exon 4 via homologous recombination along with a floxed neo cassette. Mice carrying both the R129Q and the floxed neo were fertile and showed no overt phenotype. Crossing with Tg(EIIa-cre)C5379Lmgd mice removed the neo cassette. The presence of the R192Q mutation in the resulting animals was confirmed by PCR and restriction enzyme digestion. Semi-quantitative Western blot analysis indicated that the mutant protein was expressed as well as the normal protein. (J:88693)
