Name: fibroblast growth factor receptor 3; targeted mutation 1.1, Tomoko Iwata
MGI ID: MGI:2388062
Synonyms: Fgf3K644M, SADDAN
Gene: Fgfr3  Location: Chr5:33721674-33737067 bp, + strand  Genetic Position: Chr5, 17.83 cM, cytoband B
Germline Transmission:  Earliest citation of germline transmission: J:70061
Parent Cell Line:  TC1/TC-1 (ES Cell)
Strain of Origin:  129S6/SvEvTac
Allele Type:    Targeted (Constitutively active)
Mutation:    Nucleotide substitutions
Mutation detailsFgfr3tm1Iwa animals carry a lysine to methionine substitution at residue 644 (K644M) of exon 10 and a floxed neo cassette in intron 10. The neo cassette was removed by crossing Fgfr3tm1Iwa mutants to the cre expressing line, TgN(EIIa-cre)C5379Lmgd. Northern blot analysis of brain RNA from mutant animals showed a similar level of gene expression as wild-type. (J:70061)
