Gene: Tnf  Location: Chr17:35418357-35420983 bp, - strand  Genetic Position: Chr17, 18.59 cM
Alliance: Tnftm1Gkl page
Germline Transmission:  Earliest citation of germline transmission: J:47673
Parent Cell Line:  CCE/EK.CCE (ES Cell)
Strain of Origin:  129S/SvEv-Gpi1c
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsReplacement of 40 bp of the 5' UTR, all the coding region, including the ATG translation initiation codon, of the first exon and part of the first intron with MC1neopA cassette. Northern blot analysis of LPS stimulated macrophages confirmed disruption of Tnf mRNA expression. (J:47673)
