| Primary Identifier | MGI:2178631 | Allele Type | Targeted |
| Attribute String | Null/knockout | Gene | Drd4 |
| Transmission | Germline | Strain of Origin | 129P2/OlaHsd |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A neomycin resistance cassette replaced exon 2. RT-PCR analysis demonstrated that a mutated transcript was produced from this allele that spliced exon 1 to exon 3. This mutation causes a shift in the reading frame that is predicted to result in the production of a truncated protein. |
