Abstract

When cultures of fibroblast-like cells from inbred mouse strains RBC/Dn and AEJ/GnRk were exposed to 5-fluorodeoxyuridine (FUdR), non-random strain-specific distributions of chromosome gaps, breaks and exchanges were observed. Throughout the genomes there appeared to be specific sites at which lesions occurred preferentially. Two strain-specific fragile sites were identified in strain RBC/Dn at G-band 15A2, and at G-band 19B in strain AEJ/GnRk. Constitutive fragile sites at G-bands 12A2 and 18A2 were identified in both strains. A strain-specific marker at G-band 9B was found in strain AEJ/GnRk. The fragile sites reported here provide an animal model for the study of chromosome fragility as well as polymorphic markers for linkage studies.
