23. data support a model wherein ubiquitin chains at DNA damage sites are used as a targeting mechanism by specific BRCA1 complexes; RAP80 may represent a new class of DNA repair proteins that uses tandem UIM domains as part of its recruitment to DSBs PMID: 17525341

29. Mutational analysis in 168 multiple-case breast/ovarian cancer families, negative for mutations in BRCA1 or BRCA2, suggests that RAP80 does not play an important role as a high penetrance breast cancer susceptibility gene. PMID: 18270812
30. Truncating mutations of the RAP80 gene do not seem to be a cause of familial breast cancer. A novel RAP80 haplotype or rare missense mutations (p.Ala342Thr, p.Met353Thr and p.Tyr575Asp) may be associated with a modest increased risk of breast cancer. PMID: 18306035
