The specific HRR mutations identified in the 21 tumour samples were: BRIP1 (n = 5), CDK12 (n = 3), RAD54L (n = 2), RAD51B (n = 2), RAD54L rearr (n = 1), ATM rearr (n = 1), FANCA rearr (n = 1), FANCD2 (n = 1), FANCL rearr (n = 1), FANCL (n = 1), RAD51C (n = 1), RAD52 del (n = 1), XRCC3 rearr (n = 1) (Fig. 1). The gene discussed is RAD51C; the disease is neoplasm.
