Relationship between HRD status and DNA promoter methylation of HRR-related genes. (A) BRCA1 methylation. Left: HRD cases; Center: non-HRD cases. X-axis: Average values of two BRCA1 mRNA expression probes normalized to 0–1. Y-axis: β value of cg04658354. Right: Distribution of BRCA1 methylated cases. (B) RAD51C methylation. X-axis: Average values of two RAD51C mRNA expression probes normalized to 0–1. Y-axis: β value of cg14837411. RAD51C methylation cases are surrounded by a blue line in the upper-left region. The frequency of RAD51C methylation differs greatly between HRD cases (left) and non-HRD cases (right).
