| Gene | Axin1 | Inheritance Mode | Recessive |
| Strain of Origin | (CBA/J x C57BL/6J)F2 | Is Recombinase | false |
| Is Wild Type | false |
| molecularNote | In this mutation, an ~600 kb transgene is inserted between exons 1 and 3, and exon 2 and 20 kb from the two flanking introns are deleted. This disruption results in the absence of the major wild-type 3.9 kb mRNA in homozygotes. |
