Description
Approximately 75% of homozygotes die before birth of unknown causes. The surviving homozygous females are sterile. Mice that are heterozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No gene product (mRNA) is detected by Northern blot or real-time RT-PCR analysis of homozygous knockout ES cells lines produced from mutant mice. Homozygous embryos exhibit development delays as early as embryonic day 8.5, and loss of homozygous embryos occurs E11.5 to E18.5. Approximately 16% of homozygous embryos, at E10.5 or younger, are partially or completely outside the yolk sac. Embryonic primordial germ cell migration is mislocalized. A reduced number of gonocytes/germ cells in homozygotes is detectable as early as E11.5. Homozygous adult females have smaller size ovaries when compared to wildtype littermates. Ovaries from 5 to 8 week old homozygotes have few follicles, and in ovaries from homozygous females 10 weeks of age or older, no follicles are observed. Although, homozygous males are fertile, testes from homozygous males have some empty seminiferous tubules.

Development
A targeting vector containing a PGK-NEO cassette was used to disrupt 2 kb of sequence encoding both genes. The construct was electroporated into (C57BL/6 x 129S4/SvJae)F1 derived V6.5 embryonic stem (ES) cells. Correctly targeted ES cells were injected into B6D2F2 blastocysts. Male germline transmission of the mutation was confirmed. The mice were maintained on a mixed B6;129S4 background. Upon arrival at The Jackson Laboratory, the mice were crossed to C57BL/6J (Stock No. 000664) at least once to establish the colony.

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.
