These transgenic mice express a S662G (serine -> glycine) amino acid mutation in the human PER2 (period homolog 2 (Drosophila)) gene, associated with familial advanced sleep phase syndrome (FASPS). The phenotype of these mice is reported to faithfully recapitulate the condition found in humans. Animals from both founder lines 864 and 867 demonstrate a short circadian period (21.6 hours in hemizygotes and 20.7 hours in homozygotes versus 23.7 hours in wildtype controls) and an advanced sleep phase. This strain may be useful in studies of familial advanced sleep phase syndrome (FASPS) and PER2 regulation of circadian rhythms.
The full-length sequence of the human PER2 gene carried in BAC RP11-139K17 was modified to change serine residue 662 to aspartic acid (S662G, AGT->GGT). It is not known what genetic background the mutation was created on, but the strain was backcrossed more than 15 times to C57BL/6 (see SNP note below) by the donating laboratory. This is founder line 867.
A 32 SNP (single nucleotide polymorphism) panel analysis, with 27 markers covering all 19 chromosomes and the X chromosome, as well as 5 markers that distinguish between the C57BL/6J and C57BL/6N substrains, was performed on the rederived living colony at The Jackson Laboratory Repository. While the 27 markers throughout the genome suggested a C57BL/6 genetic background, at least 4 of 5 markers that determine C57BL/6J from C57BL/6N were found to be segregating. These data suggest the mice sent to The Jackson Laboratory Repository were on a mixed C57BL/6J ; C57BL/6N genetic background.

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 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.
