The semidominant lens opacity 20 (Lop20) mutation in gamma crystallin c causes small eyes, with homozygotes having eyes that are only 30 to 50% the size of wildtype and heterozygotes having eyes that are approximately 75% the size of wildtype. Both homozygotes and heterozygotes develop cataracts that are evident by 1 month of age with dense nuclear opacification with irregular edges at the junction between the nucleus and cortex, and the cortex subsequently becomes cloudy.
The lens opacity 20 (Lop20) mutation was identified in an F1 hybrid mouse from a cross of BALB/cJ x A/J. This semidominant mutation was backcrossed at least once to BALB/cJ then the strain was maintained by sibling intercrossing and eventually maintained homozygous for Lop20. Sperm was cryopreserved from homozygous males at generation F20.

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.
