C57BL/6J-Oca2^p-un+5J/J

Stock number: 001513
Product name: revertant 5 Jackson
Research areas: Dermatology Research, Mouse/Human Gene Homologs

Description

These mice carry a spontaneous revertant mutation at the Oca2 locus characterized by normal hair and eye pigmentation.

Detailed description

Mice homozygous or heterozygous for the Oca2^p-un+5J allele 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. Homozygotes and heterozygotes for this revertant allele are phenotypically indisting uishable from wild-type.

Development

The C57BL/6J-Oca2^p-un+5J 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

Name: pink-eyed dilution unstable wild-type revertant 5 Jackson
MGI accession ID: MGI:2152527
Generation method: Spontaneous
Synonyms: p^un+5J
Marker symbol: Oca2
Marker name: oculocutaneous albinism II
Marker synonyms: BEY; BEY1; BEY2; BOCA; D15S12; D7H15S12; EYCL; EYCL2; EYCL3; HCL3; P; PED; SHEP1; SLC13B1

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.
