Fanconi Anemia: Interplay Between DNA Repair Defects, Mitochondrial Dysfunction, and Oxidative Stress

Fanconi anemia (FA) is a rare inherited disorder classically defined by defective DNA interstrand crosslink repair, leading to bone marrow failure and cancer predisposition. Increasing evidence indicates that FA pathophysiology extends beyond genomic instability to include mitochondrial dysfunction, oxidative stress, and impaired antioxidant responses. Across multiple cellular models and patient-derived samples, FA cells display altered mitochondrial bioenergetics, increased reactive oxygen spec
