Four haplotypes within two genes (NBS1 and BRIP1) involved in the monoubiquitinated FANCD2-DNA damage-repair pathway are significantly associated with increased sporadic breast cancer risk, while one haplotype within NBS1 is correlated with an increased risk of familial or early-onset breast cancer, indicating that specific haplotypes may be distinct predictors of breast cancer.
