We identified 10 mutations in BRCA2 exon 11 in 72 mammary tumor samples by comparing with the consensus sequence: 2135A>G (E643K), 2213A>G (N669D), 2329T>C (synonymous), 2609A>C (K801Q), 2696A>G (I830V), 3538T>G (I1110M), 4481A>C (T1425P), 4512A>G (K1435R), 5788G>A (synonymous), and 6886A>G (I2226M) (Table 1 and Supplemental Table S2). This evidence concerns the gene BRCA2 and breast cancer.
