Symbol: Scn2atm1Mml
Name: sodium channel, voltage-gated, type II, alpha; targeted mutation 1, Mauricio Montal
MGI ID: MGI:2180186
Synonyms: NaCh(alphaII)-
Gene: Scn2a  Location: Chr2:65620771-65767447 bp, + strand  Genetic Position: Chr2, 38.61 cM
Germline Transmission:  Earliest citation of germline transmission: J:76457
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsMost of exon 1, which encodes amino acids 1-89, was replaced with a neomycin resistance gene via homologous recombination. RNase protection assays using whole brain preparations from homozygous mutant animals revealed a greater than 85% reduction in gene expression compared to wild-type. Protein expression was barely detectable as determined by Western blot analysis. (J:76457)
