In the context of MH Guide,VAF/Copy reported biomarkers predict a patient's response to Potential impact Treatment Drug approval Biomarker Biomarker score Trials therapy and are based on the characterization of the patient/tumor genomic DNA. Depending Numberon the analysis type, such genomic characteristics can include single variants (SNVs), insertions and deletions (indels), fusion genes, and copy number alterations (CNAs).
