Associations between functional HRR deficiency scores and maximum PSA50 response.
LOH 0.75:
Loss of heterozygosity (LOH) score, measuring the degree of LOH based on discontinuous SNP typing. LOH events larger than 75% of the respective chromosome arm length are excluded from the score analysis.
LOH-score: Number of LOH events assessed using the scarHRD tool. This score represents number of LOH regions exceeding 15 Mb that do not cover the whole chromosome.
TAI-score: Telomeric allelic imbalance (TAI) reflects the number of sub-chromosomal regions with allelic imbalance extending to the telomere.
LST-score:
Number of large-scale state transitions (LST) assessed using the scarHRD tool. The LST score represents the number of chromosomal breaks between adjacent regions of at least 10 Mb length, with a distance between events not more than 3Mb.
HRD-score: Defined as sum of the burden of LOH-Scar, LST-Scar and TAI-scar (LOH-Scar score+ TAI-Scar score +LST-scar)
