The region of chromosome 9 that contains the Frataxin (FXN) locus is prone to breakage and rearrangements.This chromosome fragility involves the generation of chromosome/chromatid gaps or breaks, or the high frequency loss of one or both copies of the affected gene when cells are grown under folate stress or as we showed previously, in the presence of an inhibitor of the ATM checkpoint kinase.
