| Attribute String | Null/knockout | Gene | Ednrb |
| Transmission | Germline | Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl<+> |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A LoxP site was inserted upstream of the start codon within the second exon of the targeted gene. A second LoxP site was placed downstream of the second exon, within the second intron. Recombinase mediated recombination removed the selection cassette and exon 2. |
