SUMMARY:

Two brothers had aplastic anemia similar to Fanconi anemia but without associated congenital abnormalities. Both had mild clinical courses and prolonged response to androgen therapy, one had persistent remission for 3 years after therapy. Cultured peripheral lymphocytes of both patients showed a high prevalence of chromosomal breaks characteristic of Fanconi anemia. Electron microscopy did not show a morphologic basis for the chromosomal breaks. One brother had a stable translocation chromosome in bone marrow erythroid and myeloid cells. The other's cultured skin fibroblasts showed an increased susceptibility to "malignant" transformation by SV40 virus, a finding also characteristic of Fanconi anemia.

Skin fibroblasts from the normal mother and a normal sister showed an increased susceptibility to "malignant" transformation, suggesting that this test may provide a means of detecting the heterozygous carrier state. Since the patients studied could not be diagnosed as having Fanconi anemia on clinical grounds alone but did appear to represent a variant of the disease on the basis of chromosomal analysis and viral transformation studies, these tests may prove to be useful in distinguishing Fanconi-type anemia from other familial aplastic anemias and in predicting response to therapy.
