Distribution of scores in BRCA1/2 -intact and BRCA1/2 -deficient samples. (A) Homologous recombination deficiency-loss of heterozygosity (HRD-LOH) score. (B) Homologous recombination deficiency-telomeric allelic imbalance (HRD-TAI) score. (C) Homologous recombination deficiency-large-scale state transition (HRD-LST) score. (D) Mean of the homologous recombination deficiency (HRD-Mean) score. Red bars, BRCA1/2-intact samples; blue bars, BRCA1/2-deficient samples.
