Mapping the 66‐gene set using the STRING protein–protein interaction networks (Fig 7D) generated a highly connected network consisting of DNA damage response genes that include many regulators of homologous recombination (such as BRCA2, RAD51B, RAD51C, and PALB2), components of the Fanconi anemia pathway (such as FANCM, TELO2, and SLX4), as well as the CHEK1 and XPC. Here, XPC is linked to Fanconi anemia.
