GenerationF102p

Appearance
pink-eyed chinchilla with rough coat
Related Genotype: A/A Tyrp1b/Tyrp1b Oca2p Tyrc-ch Mod2b Myo7ash1 Hbbd fr/Oca2p Tyrc-ch Mod2b Myo7ash1 Hbbd fr

Important Note
This strain is homozygous for Mod2b, Myo5ash1, Hbbd, and fr.

Strain Description
The FS/Ei strain was originally used as a linkage testing stock for gene mapping. It is homozygous for several visible recessive mutations including brown (Tyrp1b), pink-eyed dilution (Oca2p), chinchilla (Tyrc-ch), frizzy (fr), and the neurological mutation shaker 1 (Myo7ash1). It is also homozygous for a couple allelic variants that can be easily typed (Mod2b and Hbbd). Mice homozygous for the shaker 1 show circling, head-tossing, deafness, and hyperactivity characteristic of this type of mutant mice. Viability is normal, and breeding ability is high for a circling mutant. Homozygous mutant mice are most often deaf and swim well on the surface of water up to 4 weeks of age and more but lose the ability later. The degenerative changes of the labyrinth may occur a little later than in some of the other waltzing mutants. By light microscopy, the changes are seen to consist of degeneration of the organ of Corti, the spiral ganglion, and the stria vascularis in the cochlea, and of the saccular macula and the vestibular ganglion in the vestibular labyrinth.

Strain Development
The original shaker-1 mutation was found by Lord and Gates in 1929 (Lord, E.M.and W.H. Gates Am. Nat. 69:435-442). It arose in the Bagg albino stock of MacDowell 1929. It was maintained at the Jackson Laboratory in the pink-eye chinchilla shaker-1 stock of Dr. G. D. Snell. This stock was of mixed origin and had come from a cross of DBA and a pink-eyed chinchilla shaker-1 strain carrying a translocation described only as T(1;?)c. The mutation frizzy (fr) which arose spontaneously in the stock was also maintained in it and inbreeding was as a homozygous stock started in 1954. The stock is now known as the FS/Ei strain and is homozygous for Mod2b, Myo7ash1, Hbbd and fr as well as Oca2p, Tyrc-ch and Tyrp1b. It was cryopreserved by mating homozygotes at F102 in 1993.

Molecular Note A G-to-C transversion mutation is predicted to result in an arginine to proline change at position 502 in the encoded protein. This mutation is predicted to lie within the head domain of the protein. Northern blot analysis indicated that mRNA expression, size, and stability were unaffected. Immunoblot analysis showed that normal levels of the protein was expressed. [MGI Ref ID J:23257]

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.
One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services: Tel: 1-800-422-6423 or 1-207-288-5845; Email: jaxservices@jax.org.

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.
