Symbol: Spg20tm1.1Xen
Name: spastic paraplegia 20, spartin (Troyer syndrome) homolog (human); targeted mutation 1.1, Taconic Biosciences
MGI ID: MGI:5430946
Gene: Spg20  Location: Chr3:55019529-55044743 bp, + strand  Genetic Position: Chr3, 26.53 cM
Alliance: Spg20tm1.1Xen page
Germline Transmission:  Earliest citation of germline transmission: J:185987
Parent Cell Line:  Not Specified (ES Cell)
Strain of Origin:  Not Specified
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsMost of exon 2 and all of exons 3 through 5 were replaced with a luciferase reporter and a floxed neo cassette. Cre-mediated recombination removed the neo cassette. Western blot analysis confirmed the absence of protein expression in the brain, spinal cord and testis. (J:185987)
