C57BL/6J-Oca2^p-un+6J/J

Stock number: 001499
Product name: revertant 6 Jackson
Research areas: Dermatology Research, Mouse/Human Gene Homologs

Description

These mice carry a spontaneous revertant mutation at the Oca2 locus.

Detailed description

Homozygotes and heterozygotes for this revertant allele are phenotypically indistinguishable from wild-type.

Mice homozygous or heterozygous for Oca2^p-un+6J exhibit normal hair and eye pigmentation. Heterozygotes also carrying a mutant Oca2^p allele that, when homozygous, produces a recognizable pink-eyed dilution phenotype can be distinguished by test-crossing them to known heterozygotes or pink-eyed dilution mice.

Development

The C57BL/6J-Oca2^p-un+6J strain was created by mating Oca2^p-un individuals having at least 50% wild-type pigmentation to nonmosaic Oca2^p-un/Oca2^p-un sibs. Pigmented offspring of this mating were intercrossed to obtain mice homozygous for the revertant allele.

Allele

Symbol: Oca2^p-un+6J
Name: pink-eyed dilution unstable wild-type revertant 6 Jackson
MGI accession ID: MGI:2152528
Generation method: Spontaneous
Marker symbol: Oca2
Marker name: oculocutaneous albinism II
Chromosome: 7
Strain of origin: C57BL/6J-Oca2^p-un
Molecular note: Removal, presumably by unequal homologous recombination, of an ~70 kb DNA duplication derived from retroviral-like intracisternal A particles that characterizes p^un, restores wild-type coat pigmentation.
