Germline Transmission:  Earliest citation of germline transmission: J:72915
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+

Mutation:    Insertion
Mutation detailsThis 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 Hdh and was found to be a hypomorhic allele, expressing reduced levels of the mutant protein. (J:72915)
