ATR and anemia: These include mutations in BRCA1 and BRCA2, RAD51 (locator of the DNA repair complex to the broken DNA strand), Ataxia-Telangiectasia Mutated (ATM), ATR Serine/Threonine Kinase (ATR—two DNA-damage sensory proteins), BRCA1 Associated RING Domain 1 (BARD1), BRCA1 Interacting Protein 1 (BRIP1), cyclin-dependent kinase 12 (CDK12), Partner and localizer of the BRCA2 (PALB2), and Fanconi anemia complementation group (FANC—that constitutes a complex cooperating with BRCA in DNA repair) [34,35].
