RAD51C and Fanconi anemia: Although they mainly affect the BRCA1 and BRCA2 genes, they have been detected in other genes such as RAD51C hypermethylation (RAD51 paralog C), ATM (ataxia telangiectasia mutated serine-protein kinase gene), or ATR mutations, and mutations of the HR interacting Fanconi anemia gene [42,43,44].
