Appearance
black
Related Genotype: a/a

Description
Mice homozygous for the Cgatm1Sac targeted mutation are viable but both sexes are infertile. They lack TSH, LH, and FSH. Homozygous mutant mice are hypogonadal and exhibit severe hypothyroidism resulting in dwarfism. Development of the thyroid gland was arrested in late gestation. However, gonadotropin releasing hormone (GNRH) neuron migration, development of secondary sex organs, and fetal and neonatal gonadal development are normal. Mice heterozygous for the Cgatm1Sac targeted mutation appear normal.

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.
