Strain Description
The pink-eyed unstable (Oca2^p-un) mutation comprises a 70-kb, head-to-tail duplication of a transcribed region of the Oca2^p gene. Oca2^p-un homozygotes have a greatly diluted coat color and pink eyes; however, approximately 3.5% of Oca2^p-un/Oca2^p-un mice are mosaic for wild-type coat color (Melvold et al., 1971) because of somatic reversion of the mutation involving loss of the duplicated segment (Brilliant et al.1991, Gondo et al. 1993).

Strain Development
The Oca2^p-un mutation occurred spontaneously in the C57BL/6J strain.

General Note		pun, pink-eyed unstable, recessive. This mutation arose spontaneously in the C57BL/6J strain. Homozygotes resemble p/p mice phenotypically, but pun reverts somatically to wild type with high frequency. The reversion rate varies with age, beinghighest at 2 and at 10 days of gestation, and with genotype of parents, being higher in pun homozygous progeny of heterozygous parents (pun/+ or pun/p mated inter se) than of homozygous pun parents (J:5526). Whitney and Lamoreux (J:6739) suggest that pun may have been produced by insertion of a transposable element into the wild type p locus gene, frequent excision of the element being responsible for the high reversion rate. Subsequently Brilliant et al. (J:2230) have shown that in the pun mutation, coding sequences of the p gene are interrupted by a head-to-tail tandem duplication of genomic DNA, one copy of which appears to be lost in revertant mice (J:3762). In the pigmented retinal epithelium, darkly pigmented revertant cells occur with greater frequency in the more distal or anterior part of the epithelial layer than in the proximal part near the optic nerve, indicating that the rate of reversion is conditioned by the tissue environment (J:7305). Homozygous pun mice, in common with some other mutations that reduce pigmentation, have a reduced number of projections of retinal ganglion cells to the ipsilateral lateral geniculate nucleus (J:6064).
Molecular Note		High-resolution Southern blots of genomic DNA hybridized to dispersed and moderately repetitive DNA sequences showed this allele has a DNA duplication derived from a sequence family encoding the retroviral-like intracisternal A particles. The IAP duplication is part of a much larger duplicated segment of DNA. [MGI Ref ID J:11138]

Standard Supply	Repository-Cryopreserved. Must Be Recovered. Please refer to pricing and supply notes for further information.
Supply Notes	Cryorecovery - Standard. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX^® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX^® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX^® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
