BRC No.RBRC09758
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6;129P2-Chd8<tm1Kei>
Former Common nameChd8/Duplin KO
H-2 Haplotype
ES Cell lineE14 [129P2/OlaHsd]
Background strainC57BL/6JJcl
Strain developmentDeposited by Keiichi Nakayama, Medical Institute of Bioregulation, Kyusyu University in 2016. E14(129P2/OlaHsd) ES cell line was used. Mixed genetic background in C57BL/6 and 129P2.
Strain descriptionChd8 (chromodomain helicase DNA binding protein 8) knockout mice. Homozygous mutants are lethal. Heterozygous mutant displays autistic like behavior. All exons were replaced by loxP-neo cassette. Mouse strain carrying deletion of only long isoform of Chd8 (Chd8l) is available as RBRC09759.
