| Attribute String | Null/knockout | Gene | Hrh1 |
| Transmission | Germline | Strain of Origin | 129P2/OlaHsd |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A 0.8 kb fragment containing the initiation codon was replaced with a neomycin selection cassette inserted in reverse transcriptional orientation relative to the gene. Receptor binding studies on brain sections of homozygous mice confirmed that no functional protein was made from this allele. |
