摘要：

To identify novel susceptibility genes for hepatocellular carcinoma (HCC), we performed a rare -variant association study in Chinese populations consisting of 2,750 cases and 4,153 controls. We identified four HCCassociated genes, including NRDE2 , RANBP17 , RTEL1 , and STEAP3 . Using NRDE2 (index rs199890497 [p.N377I], p = 1.19 3 10 - 9 ) as an exemplary candidate, we demonstrated that it promotes homologous recombination (HR) repair and suppresses HCC. Mechanistically, NRDE2 binds to the subunits of casein kinase 2 (CK2) and facilitates the assembly and activity of the CK2 holoenzyme. This NRDE2-mediated enhancement of CK2 activity increases the phosphorylation of MDC1 and then facilitates the HR repair. These functions are eliminated almost completely by the NRDE2-p.N377I variant, which sensitizes the HCC cells to poly(ADP-ribose) polymerase (PARP) inhibitors, especially when combined with chemotherapy. Collectively, our findings highlight the relevance of the rare variants to genetic susceptibility to HCC, which would be helpful for the precise treatment of this malignancy.
