The PfasSofa semidominant allelic series on the C57BL/6J background all cause a short snout and related craniofacial defects, along with variably penetrant phenotypes of white belly spot and tail tip.

Short face 3 Jackson heterozygotes have craniofacial defects, most notably short noses. Some have a white belly spot or tail tip, but these phenotypes have incomplete penetrance. PIXImus densitometric measurements of body composition at 12 weeks of age showed decreased whole body fat and percent fat in females, but not males, and body weights taken after 5 weeks of age until 13 weeks of age show a slight reduction in body mass in both female and male heterozygotes compared with wild type sibling controls. Heterozygotes are viable and fertile.
The short face 3 Jackson mutation arose spontaneously in the B6.129S7-Rag1tm1Mom/J strain at The Jackson Laboratory. The Rag1tm1Mom allele was bred out of this mutant subline and sperm was cryopreserved from PfasSofa-3J heterozygous males.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
