BARD1 and ovarian carcinoma: We conducted telomere FISH experiments using peripheral blood lymphocytes from breast and ovarian cancer patients with germline mutations in BARD1 or BRCA1, namely BARD1 c.1690C > T, BARD1c.1972C > T, BARD1c.1977A > G, BRCA1 c.5266dupC [48], and the BRCA1 c.5266dupC and BARD1 c.1690C > T double mutation (Supplementary Figure S1B), as well as from healthy control subjects.
