| Primary Identifier | MGI:1856712 | Allele Type | Spontaneous |
| Gene | Hps1 | Inheritance Mode | Recessive |
| Strain of Origin | C3HeB/FeJ | Is Recombinase | false |
| Is Wild Type | false |
| description | Genbank ID for mutant allele: AF003867 |
| molecularNote | The underlying mutation responsible for the phenotype in the pale ear mouse was identified as an insertion of an intracisternal A particle in a protein coding- 3' exon of the Hps1 gene. Northern analysis demonstrated qualitative differences in mRNA between wild-type and homozygous mutant animals. |
