• Strain of Origin: (129X1/SvJ x 129S1/Sv)F1-Kitl⁺

Mutation description

• Allele Type: Targeted (Humanized sequence)
• Mutation: Insertion
• Mutation details: This allele carries 18 CAG repeat units, with 20 glutamines, in the first exon of the endogenous gene and a floxed neo cassette in the promoter. This allele models the number of CAG repeats found in the human Htt and was found to be a hypomorphic allele, expressing reduced levels of the mutant protein. (J:72915)
