Components of the Fanconi anemia (FA) and HR pathways, including RAD51 (FANCR), FANCD2, BRCA1 (FANCS), and BRCA2 (FANCD1), play a vital role in protecting nascent DNA at reversed replication forks (Schlacher et al., 2011, Schlacher et al., 2012, Somyajit et al., 2015, Ying et al., 2012, Zadorozhny et al., 2017). This evidence concerns the gene BRCA2 and Fanconi anemia.
