FANCD2 and cervical carcinoma: We compared our cervical carcinoma cell line derived FANCD2 mapped fragile sites (genomic coverage 7.9%) to the 77 aphidicolin-induced common fragile sites (FRA regions) defined cytogenetically in lymphocytes and reported in the HGNC (HUGO Gene Nomenclature Committee) database (genomic coverage 48.3%) (Fig. 5a).
