The final, formatted version of the article will be published soon.

    demonstrated high concordance in HRD status with reference test (Kappa 0.8, 95% CI 0.60-0.98). Overall accuracy, sensitivity and specificity were 90%. Six samples had BRCA1/2 mutations in myChoice ® HRD Plus CDx, all detected by GS Focus HRD test.In summary, the results demonstrate substantial agreement and high accuracy of NGS-based GS Focus HRD test as compared to myChoice ® HRD Plus CDx.Our in-house assay is eligible for diagnostic test approval and market access as per Brazilian regulations.
