“…Genes whose products are known to interact with BRCA1/2 and to be involved in DNA repair or cell cycle regulation are particularly attractive candidates for breast cancer susceptibility genes [22,60]. As a consequence, genes such as ATM, BRIP1, CHEK2, NBS1, PALB2, RAD50 and BARD1 have been analysed for the presence of germline mutations which may explain increased breast and/or ovarian cancer risk [8,12,16,23,35,38,43,46,48,50,[53][54][55].…”
