In addition, a subset of nineteen established and candidate breast or ovarian cancer genes (ATM, BARD1, BRCA1, BRCA2, BRIP1, CDH1, CHEK2, MLH1, MSH2, MSH6, NBN, NF1, PALB2, PMS2, PTEN, RAD51C, RAD51D, STK11 and TP53) were investigated for all sequence variants. This evidence concerns the gene NBN and ovarian cancer.
