Germline Transmission:  Earliest citation of germline transmission: J:161191
Parent Cell Line:  Pat5 (ES Cell)
Strain of Origin:  129X1/SvJ
Allele Type:    Targeted (Humanized sequence)
Mutations:    Insertion, Nucleotide substitutions
Mutation detailsExon 26 was replaced with an frt flanked neo cassette and a modified exon 26 in which nucleotide substitution results in the amino acid substitution of histidine for arginine at position 1648 (R1648H), mimicking a mutation found in human generalized epilepsy with febrile seizures plus (GEFS+) patients. Flp mediated recombination removed the neo cassette. (J:161191)
