Mating SystemHomozygote x Heterozygote         (Female x Male)
Specieslaboratory mouse
GenerationN5F72 (24-DEC-08)

Appearance
black, small body size
Related Genotype: a/a Ghrhrlit/Ghrhrlit

black, unaffected
Related Genotype: a/a Ghrhrlit/+

Description
Mice homozygous for the little spontaneous mutation (Ghrhrlit) are characterized by a deficiency in pituitary growth hormone and prolactin and growth retardation. Male mice have reduced fertility and female mice show a delay in lactation.

Development
The little (Ghrhrlit) mutation arose spontaneously in C57BL/6J at The Jackson Laboratory in 1970. It has been maintained on this background through sibling matings with occasional backcrosses to C57BL/6J. In 1983 C57BL/6J females were bred to heterozygous males to generate embryos for cryopreservation.

Genes & Alleles

Gene & Allele Information

 
Allele Symbol Ghrhrlit
Allele Name little
Allele Type Spontaneous
Common Name(s) lit; litm;
Strain of OriginC57BL/6J
Gene Symbol and Name Ghrhr, growth hormone releasing hormone receptor
Chromosome 6
Gene Common Name(s) GHRFR; GHRHREC; GHRHRpsv; GRFR; Ghrfr; growth hormone releasing factor receptor; lit; little;
Molecular Note The mutation in little mice is a A-to-G transition in codon 60 that is predicted to alter this residue from a aspartate to a glycine in the encoded protein. Reduced levels of mRNA were noted in total RNA derived from pituitary of homozygous mice, and invitro assays demonstrated that no functional protein is made from this allele.

Standard SupplyRepository-Live. A collection of over 1000 strains maintained as live colonies. Individual colonies are sized to meet current customer demand. Delivery for orders of 10 mice or less ranges on average from one to eight weeks; mice are generally shipped between four to six weeks of age with a maximum shipping age of ~nine weeks. Colony sizes do not generally support stringent age specifications for large volumes of mice; however custom orders and larger quantities of mice are easily arranged. Estimated ship dates for all orders provided within 48 hours of order placement.

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.
