| Primary Identifier | MGI:3045164 | Allele Type | Spontaneous |
| Gene | Sls | Strain of Origin | C57BL/6J |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | This spontaneous mutation arose at The Jackson Laboratory. This mutation causes a phenotype similar to that of the original lethal spotting mutation, and maps to the same region of Chr 2; however, as this allele is dominant, no complementation test was performed. |
