Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutation: Intragenic deletion
• Mutation details: This allele was generated from Fmn1^tm1Zlr by crossing to Tg(CMV-cre)1Cgn mice. Cre expression causes the excision of 170 kb containing the remaining exons between 9 and 24; the hygro cassette is also deleted. The predicted protein product is similar to that of Fmn1^tm1Zlr in that the translation is out-of-frame after exon 9. In addition, transcription of Grem1 is disrupted owing to the deletion of a Grem1 regulatory region in an Fmn1 intron. (J:91385)

Notes

Homozygous mutant mice display limb deformities and a low frequency of renal abnormalities, but not renal agenesis or aberrant lung patterning phenotypes. This mutation is a hypomorphic allele, allelic to Grem1^tm1Azun. Compound heterozygous mutant mice show a fully penetrant "limb deformity" limb phenotype, but not the phenotypes causing neonatal lethality. Transcription was not detected in the limb bud mesenchyme of compound heterozygous mutant embryos (J:91385).
