Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:86827
• Parent Cell Line: TC1/TC-1 (ES Cell)
• Strain of Origin: 129S6/SvEvTac

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: A floxed PGK-neomycin resistance gene was inserted into intron 8 and an additional loxP site was placed in intron 7, 75 bp from the start of exon 8. Both exon 8 and the neomycin gene were subsequently removed from correctly targeted ES cells by Cre-mediated recombination. A frame shift mutation is predicted at the splice site between exon 7 and exon 9 in the resulting transcript. (J:86827)
