| Primary Identifier | MGI:1861703 | Allele Type | Targeted |
| Attribute String | Humanized sequence | Gene | Htt |
| Transmission | Germline | Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl<+> |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | This allele carries 18 CAG repeat units, with 20 glutamines, in the first exon of the endogenous gene, modeling the number of CAG repeats found in the human Hdh. It is a derivative of Hdhtm6Mem in which the neo cassette has been removed via cre-mediated recombination. |
