Isca1^{tm1b(KOMP)Wtsi}/Isca1^{tm1b(KOMP)Wtsi} mice exhibit embryonic lethality, with embryos recovered at E7.5 but not at E9.5. Embryos are smaller and form a rudimentary egg cylinder but no primitive streak or hallmarks of gastrulation are seen at E7.5.

Mutation description

• Allele Type: Targeted (Null/knockout, Reporter)
• Mutations: Insertion, Intragenic deletion Vector: L1L2_Bact_P
• Mutation details: The L1L2_Bact_P cassette was inserted at position 59906420 of Chromosome 13 upstream of the critical exon(s) (Build GRCm39). The cassette is composed of an FRT site followed by lacZ sequence and a loxP site. This first loxP site was followed by neomycin resistance gene under the control of the human beta-actin promoter, SV40 polyA, a second FRT site and a second loxP site. A third loxP site was inserted downstream of the targeted exon(s) at position 59907262. The critical exon(s) were thus flanked by loxP sites, and subsequent Cre-mediated excision deleted the critical sequence and neomycin selection cassette yielding a reporter knockout allele.
