| Genetic information | The AIDel allele has a 28kb deletion on chromosome 17 between 3kb downstream of the Airn transcription start site (TSS) (Igf2r intron 2) and 2.8kb upstream of the Igf2r TSS (GRCm38/mm10, chr17: 12,744,358 -12,772,513). Additionally, Airn is truncated by a polyadenylation cassette immediately before the AIDel deletion. This allele was made by chromosome engineering by targeted meiotic recombination (Herault et al. 1998, Nature Genetics; 20:381–384), by breeding together the Airn truncation allele (FVB.129P2-AirnT, Sleutels et al. 2002, Nature; 415:810-813) and the Igf2r promoter deletion (FVB.129P2-IPD, Sleutels et al. 2003, EMBO J.; 22:3696-3704) with Hprt1-cre (B6.129S1-Hprt1-cre, Tang et al. 2002, Genesis; 32:199-202), and screening the offspring of triple mutant males for recombination events. The AIDel allele should have a 129P2 background near the deletion, and a B6/FVB mixed background in other regions of the genome. The background should be closer to FVB as the mice have been backcrossed to FVB/N for 3 generations. |
| Phenotypic information | Homozygous:Homozygous mice should be embryonic lethal between E13.5 and E18.5 due to deletion of the Igf2r promoter (Barlow et al. 1991, Nature).Heterozygous:Heterozygotes with a maternally inherited AIDel allele should be embryonic lethal between E13.5 and E18.5 due to deletion of the Igf2r promoter, while mice with a paternal inheritance of the duplication are viable and fertile. |
| Breeding history | AIDel mice were derived over 2 generations by breeding together FVB.129P2-AirnT, FVB.129P2-IPD and B6.129S1-Hprt1-cre mice, and then screening the offspring of triple mutant males for recombination events, as described in the “Genetic Description” section. The AIDel founder was then backcrossed to FVB/N for 3 generations. |
