Synonyms: Smn2B, Smn2B- no Neo
Gene: Smn1  Location: Chr13:100124852-100137690 bp, + strand  Genetic Position: Chr13, 52.99 cM, cytoband D1/D2.1
Germline Transmission:  Earliest citation of germline transmission: J:183080
Parent Cell Line:  Not Specified (ES Cell)
Strain of Origin:  129/SvJ
Allele Type:    Targeted
Mutations:    Insertion, Nucleotide substitutions
Mutation detailsA targeting vector was used to insert a 3 nucleotide mutation (gga-TTT) in exon 7 of Smn1, within an important splice enhancer element, and a floxed Neo cassette (in the opposite orientation to transcription) in intron 7. Cre mediated recombination deleted the neo cassette. (J:176267, J:183080)
