Detailed Description

Mice Homozygous for the subtle gray mutation have a moderate platelet storage pool deficiency and have decreased yellow hair pigment, although the black pigment does not appear affected. This is most evident in the juvenile coat of an agouti background mouse, while on a non-agouti (black) background the difference is difficult to discern and is noted by some reduction in the yellow hair pigment in the ear pinnae. Both female and male homozygotes have an intermediate elevated bleed time of 7.5 minutes compared with 2.2 minutes in heterozygous controls and more than 15 minutes in many other platelet storage pool deficiency models. Subtle gray homozygotes also have moderate deficiencies in platelet dense granules including a 20% reduction in dense granules per platelet, decreased platelet serotonin, decreased collagen-stimulated ATP release from platelets, and decreased platelet aggregation (Swank et al., 1996). These deficiencies are mild compared with those of other platelet storage pool deficiency models, with the subtle gray decrease in platelet serotonin being the most mild of any of the 12 models comparatively assessed by Swank et al (1998). No defects were found in the activities of beta-glucuronidase or beta-galactosidase, lysosomal enzymes of the kidney, distinguishing this from other platelet storage pool disease models such as mocha, muted, light ear, pale ear, palid or pearl (Swank et al., 1996). The subtlety in the dilution of coat color, the shorter bleed time and less severe platelet defects make this a less severe model than other platelet storage pool deficiency models.

The Clcc1^m1J spontaneous mutation, which causes increased sensitivity to endoplasmic reticulum stress in the cerebellum, was identified in C3H/HeSnJ (Jia et al., 2015) and has been found homozygous in all C3H/HeSn strains assessed at The Jackson Laboratory, including this mutant subline, which is homozygous for Clcc1^m1J.

Development

Subtle gray arose spontaneously in July 1985 in the C3H/HeDiSn-Dscam^2J colony at The Jackson Laboratory. The Dscam^2J mutation arose spontaneously in 1981 on the C3H/HeDiSn background at The Jackson Laboratory and was maintained by sibling mating until 1983 when hysterectomy rederivation was performed with a homozygous ovarian transplanted female bred to a C3H/HeSnJ male, the progeny of which were maintained by sibling mating. C3H/HeDiSn is approximately equivalent to its more evolved progeny C3H/HeSnJ inbred strain. The subtle gray mutation was cryopreserved on this C3H/HeSnJ background in 1986 when this strain was at generation F3.

Allele Name	subtle gray
Allele Type	Spontaneous
Allele Synonym(s)	subtle gray; Slc7a11^sut
Gene Symbol and Name	Slc7a11, solute carrier family 7 (cationic amino acid transporter, y+ system), member 11
Gene Synonym(s)	AI451155; 9930009M05Rik; System x^c; CCBR1; sut; xCT; x^c; RIKEN cDNA 9930009M05 gene; 9930009M05Rik; sut; expressed sequence AI451155; subtle gray
Strain of Origin	C3H/HeSnJ
Chromosome	3
Molecular Note	Sequencing revealed a large deletion extending from intron 11 through exon 12 and into the intergenic region, creating a new splice site and the replacement of exon 12 with exon 12'. 3' RACE revealed a new stop codon in exon 12' and predicted a modified and truncated protein carboxyl terminus.

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We 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.

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.
