| Attribute String | Hypomorph, Modified isoform(s) | Gene | Fgfr1 |
| Transmission | Germline | Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl<+> |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A loxP flanked neomycin cassette was inserted into intron 7, and a point mutation was introduced in IIIb that introduced an in frame stop codon to specifically disrupt expression of the IIIb isoform of the protein. This is a hypomorphic allele. |
