We screened cancer patients' tumors for FA functional defects then aimed to establish the safety/feasibility of administering PARP inhibitors as monotherapy and combined with a DNA-breaking agent.
Since the Fanconi anemia (FA) pathway coordinates several DNA repair pathways, including homologous recombination in which BRCA1 and BRCA2 play important roles, we investigated whether this pathway harbors other predictors of PARP inhibitor sensitivity.
In addition, identifying inherited mutations in a variety of FA-BRCA pathway genes may aid in identifying individuals who will selectively benefit from PARP inhibitors.
