Description
Oca2^p-J/Oca2^p-J mice exhibit significant dilution of coat color with pink eyes, a phenotype similar to that produced by Oca2^p/Oca2^p. The Oca2^p-J mutation is a partial deletion of the gene that completely ablates Oca2^p function (Oakey et al. 1996). Oca2^p-bs/Oca2^p-bs mice show a less extreme coat color dilution and have black eyes from birth; the phenotype of Oca2^p-bs homozygotes also includes stunted growth, jerky gait, male sterility, female semisterility, and impaired maternal behavior, and the smaller-than-expected proportion of Oca2^p-bs homozygous intercross offspring implies reduced prenatal viability (Lyon et al. 1992). The Oca2^p-bs mutation comprises a deletion that begins about 10 kb 5' of the Oca2^p locus and extends for about 8 kb in the proximal direction from it (Lehman et al. 1998). The deletion does not include any part of the transcribed Oca2^p sequence; the hypopigmentation of Oca2^p-bs/Oca2^p-bs mice may be due to a long-distance effect of the deletion or to some other, as yet undefined alteration of the Oca2^p sequence. The non-pigmentation aspects of the Oca2^p-bs phenotype result from the deletion of most of the Herc2 gene (Lehman et al. 1998). Oca2^p-J/Oca2^p-bs compound heterozygotes have a color phenotype intermediate between those of the two homozygotes, exhibit no behavioral abnormalities and are fertile.

Development
The Oca2^p-bs mutation was induced at the Medical Research Council Radiobiology Unit, Harwell, UK by neutron irradiation of a male mouse of unspecified lineage. Oca2^p-J occurred spontaneously in the C3H/HeJ strain at The Jackson Laboratory in 1974.

General Note		pbs, pink-eyed dilution-black-eyed sterile (formerly p24H); recessive; 960-BP DEL; 320 AA DEL: Arose in descendants of neutron treated mice (J:15082, J:2108). Homozygotes have dark eyes at birth. The coat color in adults is slightly lighter than pd but darker than pdn. At weaning, homozygotes show a slightly jerky behavior (J:15082, J:13043). Males are sterile, with a high proportion of abnormal sperm (multinucleated, multitailed, and acrosomal defects) and a reduced proportion of gonadotropiccells in the pituitary (J:49046, J:5219, J:5808). The sperm shows a loss of negative charge along the whole length of the tail (defined by the inability to stain with the positively charged colloidal iron hydroxide), suggesting that the defect in spermatogenesis may involve the Golgi apparatus and/or plasma membrane (J:11957). Females have greatly reduced fertility, with an increased proportion of polyovular follicles and no corpora lutea (J:5501). Mutant females can generally produce a small, first litter, but the pups often die neonatally due to poor maternal behavior, which may involve improper nesting (J:49046).
Molecular Note		Southern blot analyses using cDNA probes from the pink-eyed dilution locus show that this allele comprises a 5' rearrrangement in the p gene. An intergenic deletion of 960-bp near the carboxy terminus of Herc2 deletes a stretch of 320 amino acids from the predicted protein, including the HECT domain. The overall deletion for this p-region mutant is ~8.0-kb. [MGI Ref ID J:2206] [MGI Ref ID J:49046]

Health & Colony Maintenance Information

Colony Maintenance

Breeding & Husbandry	The male sterility, female semisterility and failure of females to nurture their young that are characteristic of Oca2p-bs homozygotes necessitate maintaining this mutation by mating compound heterozygotes. Oca2p-bs/Oca2p-bs females may produce one or two litters, but the pups must be fostered to survive.

Supply Notes

Cryorecovery of Strains Needing Progeny Testing. At least two untested males and two untested females (two pairs) will be recovered (eight or more mice is typical). The total number of animals provided, their gender and genotype will vary. Untested animals typically are available to ship between 13 and 16 weeks from the date of your order. If the first recovery attempt is unsuccessful, a second recovery will be done, extending the overall recovery time to approximately 25 weeks. Progeny testing is required to identify the genotype of mice of this strain, as a genotyping assay is not available. This type of testing involves breeding the recovered animals and assessing the phenotype of the offspring in order to identify animals carrying the mutation of interest. We can perform the progeny testing for you as a service or we can ship all recovered animals to you for progeny testing at your facility. If you perform the progeny testing, there is NO guarantee that a carrier will be identified. If we perform progeny testing as a service, additional breeding time will be required. In this case, when a male and female (one pair) are identified that carry the mutation, they and their offspring will be shipped. Delivery time for strains requiring progeny testing often exceeds 25 weeks and may take 12 months or more due to the difficulties in breeding some strains. The progeny testing cost is in addition to the recovery cost and is based on the number of boxes used and the time taken to produce the mice identified as carrying the mutation. Please note that identified 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. Please contact Customer Service for more information on the cost of progeny testing for a strain: Tel: 1-800-422-6423 (from U.S.A., Canada and Puerto Rico only) or 1-207-288-5845 (from any location). The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 (from U.S.A., Canada or Puerto Rico only) or 1-207-288-5845 (from any location).

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.
