BRCA1 mRNA overexpression is correlated with poor survival in NSCLC. However, BRCA1 functions depend on the interaction with BARD1 for its stability, nuclear localization, and ubiquitin ligase activity. Expression of alternatively spliced BARD1 isoforms that lack the BRCA1-interaction domain was found upregulated and correlated with poor prognosis in breast and ovarian cancer.
