FANCB and neoplasm: The 10 HR− tumour biopsies from carriers of heterozygous mutations in non-BRCA FA genes represented in Fig. 5e correspond to 2 carriers with SNPs in each of FANCD2, FANCF, FANCG, FANCI, and FANCM (one carrier had SNPs in both FANCG and FANCI), as well as one carrier with a SNP in FANCB.
