The following phenotype information may relate to a genetic background differing from this JAX® Mice strain.
am-J/a
involves: C3H/HeJ * C57BL/6J
- pigmentation phenotype
- mottled coat (MGI Ref ID J:16570)
- found in both heterozygotes and homozygotes and ranges in color from almost extreme non-agouti with little ticking to full agouti with no mottling
- skin/coat/nails phenotype
- mottled coat (MGI Ref ID J:16570)
- found in both heterozygotes and homozygotes and ranges in color from almost extreme non-agouti with little ticking to full agouti with no mottling
am-J/am-J
involves: C3H/HeJ * C57BL/6J
- pigmentation phenotype
- mottled coat (MGI Ref ID J:16570)
- found in both heterozygotes and homozygotes and ranges in color from almost extreme non-agouti with little ticking to full agouti with no mottling
- skin/coat/nails phenotype
- mottled coat (MGI Ref ID J:16570)
- found in both heterozygotes and homozygotes and ranges in color from almost extreme non-agouti with little ticking to full agouti with no mottling
- cellular phenotype
- maternal imprinting (MGI Ref ID J:16570)
- variation in coat color is influenced by the genome of the dam

| Allele Symbol | am-J | ||
|---|---|---|---|
| Allele Name | mottled agouti Jackson | ||
| Allele Type | Spontaneous | ||
| Strain of Origin | (C57BL/6J x C3H/HeJ)F1 | ||
| Gene Symbol and Name | a, nonagouti | ||
| Chromosome | 2 | ||
| Gene Common Name(s) | AGSW; AGTI; AGTIL; ASP; As; MGC126092; MGC126093; SHEP9; agouti; agouti signal protein; agouti suppressor; | ||
| General Note | This allele is dominant to a. This mutation at the agouti locus arose in a C57BL/6J x C3H/HeJ F1 male. As with am the variation in color is influenced by the genome of the dam (J:16570). | ||
| Molecular Note | This mutation appears to represent a regulatory mutation that down-regulates agouti expression. [MGI Ref ID J:24934] | ||
This strain will not have a genotyping protocol or one is not currently available.
