Rats of the BUF/Mna strain developed spontaneous epithelial thymomas morphologically
indistinguishable from human homologues at virtually 100% incidence. Segregation of
thymoma development among crosses between BUF/Mna and ACI/NMs, which has 0%
thymoma incidence, indicated that thymoma susceptibility was determined principally by a
single autosomal dominant gene Tbm-1 (thymoma in BUF/Mna rats). In these crosses,
another autosomal dominant or semidominant gene (s) contributed by ACI/NMs parents …
