PWD/PhJ is an inbred mouse strain of the subspecies Mus musculus musculus. PWD/Ph mice exhibit differences that are genetically distinct from common laboratory mice for a number of complex phenotypic characteristics. This strain is an excellent tool for mapping both single-gene (Mendelian) traits and quantitative trait loci (QTL) contributing to complex phenotypes.Read More +
PWD/PhJ is an inbred mouse strain of the subspecies Mus musculus musculus. M. m. musculus is estimated to have diverged approximately 1 million years ago from M. m. domesticus, the subspecies from which derives most of the genome of practically every laboratory mouse strain. However, the extent of polymorphism for randomly selected microsatellite markers between the two subspecies (70-80%) is nearly as great as between M. m. domesticus and Mus spretus (84%), which diverged about 3 million years ago (Montagutelli et al. 1991; Gergorova and Forejt 2000).
PWD/Ph mice exhibit differences are genetically distinct from common laboratory mice for a number of complex phenotypic characteristics, including body mass, distribution of adipose tissue, serum concentrations of intermediary metabolites, susceptibility to type I diabetes and various behavioral traits (Gregorova and Forejt 2000).
Male, but not female, F1 hybrid offspring of crosses between mice of most laboratory strains and PWD/PhJ are sterile. Known exceptions are male (C3H x PWD)F1 and (CBA x PWD)F1 mice. The locus responsible for this difference in fertility of male PWD hybrids, called hybrid sterility 1 (symbol Hst1), has been mapped to a 580 kb region of M. m. domesticus Chr 17, approximately 8.4 cM distal to the centromere, wherein reside 10 potential candidate genes that are expressed in the testes (Forejt et al. 1991; Trachtulec et al. 1997). It has been estimated that no more than 3-4 loci contribute to the sterility phenotype of laboratory strain x M. m. musculus hybrid males (Gregorova and Forejt 2000).
Typing of PWD/Ph for 37 biochemical markers revealed numerous allelic differences with standard laboratory mouse strains (von Deimling et al. 1988). Electrophoretic alleles of 25 enzymes examined were shared between PWD and laboratory strains; nine of these markers were previously analyzed in wild-caught M. m. musculus mice, whose prevalent allele of all except one marker, Mod1, was fixed in PWD. PWD exhibited alleles at three loci that were uncommon among laboratory mice, but were identified in wild-caught M. m. musculus. Six esterase genes were identified in PWD that had also been detected in Mus molossinus but whose products were absent from laboratory strains. Unique alleles were identified in PWD for three enzymes.
Genome-wide microsatellite typing for 248 loci of PWD/Ph, PWK/Ph (distributed as PWK/PhJ, Stock No. 0003715) and/or PWB/Ph - very similar inbred strains derived from M. m. musculus pairs caught in the central Czech Republic - versus mice of three inbred laboratory strains revealed upto 80% of the loci to be polymorphic between at least one PW strain and at least one inbred strain analyzed.
The high level of both phenotypic variation and DNA sequence polymorphism between PWD/PhJ and inbred laboratory strains and the fertility of hybrid offspring of both sexes from crosses between PWD/PhJ and some laboratory strain mice make this strain an excellent tool for mapping both single-gene (Mendelian) traits and quantitative trait loci (QTL) contributing to complex phenotypes. Polymorphism at the RNA level permits investigation of monoallelic expression, e.g., from parentally imprinted genes (Forejt and Gregorova 1992; Forejt et al. 1999) or in cancer cell lines (Forejt et al. 1999). Sterility of male hybrid offspring of crosses between PWD and most inbred laboratory strains provides a tool for analysis of the genetic bases for interspecies hybrid sterility.
In 2019, researchers at The Jackson Laboratory discovered this inbred strain has a nonsense mutation in Trem2 affecting codon 148 (dbSNP ID: rs107649577 [Ensembl GRCm38.p6]).
PWD/Ph is an inbred mouse strain descended from a single pair of mice of the subspecies Mus musculus musculus caught in 1972 in the "Kunratice" locality near Prague, in the central part of the Czech Repubic. The founder mice were selected on the basis of their producing sterile male offspring in matings with C57BL/10J mice. The strain was maintained from its inception by sister-brother inbreeding (Gregorova and Forejt 2000). In July 2003, PWD/Ph mice, then at generation F81, were donated to The Jackson Laboratory by Dr. Jiri Forejt, at the Institute for Molecular Genetics, Academy of Sciences of the Czech Republic, Prague. The colony at The Jackson Laboratory is descended from 8 female and 2 male mice from Dr. Forejt's colony.
Currently there are no related genes or alleles for this strain.
These mice are still very wild after 80 generations of inbreeding, and special care is needed to prevent their escape during handling. PWD/Ph mice breed well. Females produce their first litters at about 8 weeks of age and will give birth approximately every 4 weeks. The average litter size is 7. Females continue breeding until at least 8 months old; the average number of litters produced during their reproductive lifetimes has been reported to be 6-7.

|Inbred, 1 pair minimum will be supplied|
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.
