Prevalence of polyomavirus LT sequences in DNA samples from FA patients, no-FA patients and healthy controls.

aFA: Fanconi anemia patients. bThe DNA used for the analysis derived from different biological sources. The SV40 sequences were detected in DNA from 14 out of 54 (26%) peripheral blood cell samples, 8 out of 32 (16%) from lymphoblast cell lines and in none of 3 primary fibroblast cell lines. *FA vs Healthy: p: <0.005. cno-FA: patients with no-Fanconi genetic diseases: 17 Blackfan-Diamond anemia, 7 Shwachman-Diamond syndrome, 6 severe congenital neutropenia, 3congenital amegakaryocytic thrombocytopenia, 1 Pearson syndrome, 13 uncharacterized aplastic anemias.
