Type JAX® GEMM® Strain - Congenic Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Strain Species laboratory mouse Background Strain C57BL/6By Donor Strain Fancy mice Generation N23p Strain Description
A normal-size Oca2p mRNA is present in the skin of mice homozygous for the Oca2p mutation, but in greatly reduced amounts; thus, this appears to be a hypomorphic rather than a null allele. B6By.Cg-Oca2p/Oca2p/J mice are grey with pink eyes. The Oca2p mutation affects the amount of eumelanin (brown/black pigment) and the size and morphology of eumelanosomes (black pigment granules), but has little or no effect on pheomelanin (red/yellow pigment).Strain Development
Pink-eyed dilution (Oca2p) is an old mutation of the mouse fancy. It was introduced onto the C57BL/6By background by repeated backcrossing to the host strain.

| General Note |
p is a very old mutation carried in many varieties of fancy mice (J:12958). It has been suggested that the original mutation occurred in Japanese wild mice, Mus musculus molossinus (J:19782). Homozygotes have pink eyes with pigmentation very much reduced but not completely absent in both the retina and choroid. The black pigment of the hair is very much diluted, but the yellow pigment is only slightly affected. Pigment granules are irregular and shred-like in shape. The small amount of pigment they contain is of wild-type color (J:12970, J:12958). The fine structure of the pigment granules was said by Moyer (J:5001) to be disrupted, but Hearing et al. \R(J:5346) found the structure to be normal, with premature termination of the melanizationprocess. In tissue culture of the eye, the amount of pigment formed can be increased by increasing the concentration of tyrosine. This suggests that p may block the melanin-synthesizing pathway by interference with tyrosine supply (J:12726). The site of gene action is in the melanocytes and not in either the dermis or the epidermis (J:7988). A presumed p gene has been cloned (J:2206). It was isolated from mouse melanoma and melanocyte libraries and is missing or altered in six independent p mutant alleles (J:2206). By sequence comparison, the human P locus, deletions of which are associated with hypopigmentation, is orthologous to p (J:2206). P maps to Chr 15q, near the Prader--Willi syndrome locus. On the basis of this location, the p mutation has been proposed to provide a mouse model for Prader--Willi syndrome, for Angelman syndrome, for one form of hypomelanosis of Ito (J:3253), and for type II oculocutaneous albinism (J:3600). A small nuclear ribonucleoprotein particle gene Snrpn maps near p and its human ortholog in the homologous Prader--Willi region of human Chromosome 15 (J:3623). Snrpn appears to be a better candidate for the Prader-Willi syndrome ortholog. P is deleted in human type II oculocutaneous albinism, making p a model for this disease (J:3600). | ||

| 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. |

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.Ordering and Purchasing Information
