Balmaña J., et al, carried out a registry of the results of hereditary cancer multigene panels from different laboratories, reporting contradictory interpretations in 26% of the interpreted variants, with greater frequency among the CHEK2 and ATM genes, followed by RAD51C, PALB2, BARD1, NBN, and BRIP1 (Balmaña et al., 2016). Here, NBN is linked to hereditary cancer.
