BC = breast cancer; CBC = controlateral breast cancer; OC = ovarian cancer; / = no cases; M = male. The ages at diagnosis of the first cousins are in boldface type; ° IHC Allred total scores of 3 or more were reported as positive. §HER2 IHC scores: - negative, 1+ weak, 2+ moderate, 3+ strong. ^ Probability of mutation calculated by BRCAPRO software http://www.isds.duke.edu/~gp/brcapro.html; * number of additional tumours in the family and ages of onset in parentheses.
