Gene: Fmr1  Location: ChrX:67722147-67761569 bp, + strand  Genetic Position: ChrX, 34.83 cM
Alliance: Fmr1tm1.2Cidz page
Germline Transmission:  Earliest citation of germline transmission: J:108008
Parent Cell Line:  E14 (ES Cell)
Strain of Origin:  129P2/OlaHsd
Allele Type:    Targeted (Null/knockout)
Mutation:    Intragenic deletion
Mutation detailsA germline null mutation was created by crossing Fmr1 mice, which have the first coding exon floxed, with mice that express cre-recombinase in the germline (Tg(CAG-cre)13Miya). Gene inactivation was confirmed by a lack of protein expression in the brain and testes as determined by immunoblot analysis. (J:108008)
