| Primary Identifier | MGI:2661912 | Allele Type | Chemically induced (ENU) |
| Gene | Hr | Inheritance Mode | Recessive |
| Strain of Origin | C57BL/6J | Is Recombinase | false |
| Is Wild Type | false |
| molecularNote | This phenotypic mutant, identified in an ENU mutagenesis screen, was shown not to complement the rhino Jackson mutation of strain RHJ/LeJ. It is due to a C-to-T transition in non-coding exon 2 that introduces an out-of-frame ATG upstream of the normal translation start site. Hr transcript is present, but its protein level is greatly diminished in the skin of homozygous baldy mutant mice. |
