| Primary Identifier | MGI:2152544 | Allele Type | Chemically induced (ENU) |
| Gene | Ttc21b | Inheritance Mode | Recessive |
| Strain of Origin | A/J | Is Recombinase | false |
| Is Wild Type | false |
| description | The Rab23 gene has been excluded as a candidate gene for this mutation. |
| molecularNote | A developmental mutation identified in an ENU mutagenesis screen. An A to C mutation near the N-terminus converts the highly conserved glutamine at amino acid residue 15 to a proline. Western blot analysis indicates an absence of protein product in homozygotes. |
