Addition of Lynch Syndrome genes (MLH1, MSH2, MSH6, PMS2 and EPCAM) which are not classical breast cancer predisposition genes but have been shown in several studies to be associated with increased breast cancer risk would identify another 4/112 (3.6%) of mutation carriers (MLH1 = 3, MSH2 = 1). The gene discussed is PMS2; the disease is Lynch syndrome.
