Fanconi anemia (FANC) is a rare, autosomal-recessive genetic disorder that is a heterogeneous cancer susceptibility condition that manifests with a wide range of symptoms such as congenital malformations, deteriorating bone marrow failure, DNA-damage hypersensitivity, genomic instability, and increased cancer incidence. FANCD2 is a component within the protein complex that is involved in a cell's resistance to DNA cross-linking and subsequent DNA synthesis arrest that is stimulated by the insult of ionizing radiation (IR).
