Gt(ROSA)26Sortm1(HD*103Q)Xwy expresses 1 gene
Mutation detailsA targeting vector was designed with a loxP-flanked transcriptional STOP sequence immediately upstream of a neuropathogenic polyQ-mutant form of the human Huntingtin protein exon 1 (mhtt-exon1) sequence (containing 103 mixed CAA-CAG repeats, each encoding glutamine), all followed by a polyadenylation sequence. When these mice are bred with animals expressing cre under the control of a promoter of interest, The STOP signal is deleted in tissue of interest allowing conditional expression of mhtt1-exon1.
