‘Caretaker’ type gene diseases, such as Fanconi Anemia (FA), provide an opportunity to understand the fundamental mechanisms of host susceptibility to cancer. Unlike many caretaker gene diseases, where the defects have been associated with specific molecular processes, the precise underlying molecular defect in FA is unknown.
Although recent developments in the FA field have furthered our understanding of the FA pathway and its role in genomic stability, there are still unidentified FA patient groups, which means there are still unidentified FA genes. Until all the FA proteins, their complexes, and other important functional cofactors that impact the FA pathway are identified we are missing necessary pieces to complete the FA pathway puzzle.
- My current focus: To identify functionally important proteins and protein complexes within the FA pathway.
- Long-term goal: Identify functionally important proteins within the FA pathway to aid in the development of cell-free screens for small molecules that could translate into therapeutics for FA patients.
