4 About this guide The Oncomine cfdna Assays can be analyzed with the variantcaller plugin in Torrent Suite Software v5.2.1 or in Ion Reporter Software v5.2. For robust detection of low frequency somatic variants from liquid biopsy samples, we recommend to multiplex up to: 8 Oncomine Lung cfdna Assay libraries on a single Ion 530 chip. 6 Oncomine Colon cfdna Assay libraries on a single Ion 530 chip. 12 Oncomine Breast cfdna Assay libraries on a single Ion 530 chip. In Torrent Suite Software, the Planned Run templates to be used with the Oncomine cfdna Assays are listed in the following table: Application Oncology - Liquid Biopsy Torrent Suite Software template Oncomine Lung Liquid Biopsy DNA Oncomine Colon Liquid Biopsy DNA Oncomine Breast Liquid Biopsy DNA Oncomine Lung Tumor DNA Oncomine Colon Tumor DNA Oncomine Breast Tumor DNA Description Planned run template for use with cell-free DNA (cfdna) research samples. Analysis parameters are optimized for the sensitive and specific detection of rare somatic variants (SNPs, InDels) present at 0.1% frequency in cfdna. Planned run template for use with solid tumor research samples from FFPE as well as fresh frozen tumor tissue. Analysis parameters are optimized for the sensitive and specific detection of rare somatic variants (SNPs, InDels) present at 0.5% frequency. Analysis parameters are optimized to eliminate false positives due to DNA damage resulting from formalin fixation. 4 Oncomine cfdna Assays, Part III: Variant Analysis User Guide

5 1 VariantCaller Plugin variant analysis Review Oncomine cfdna assay run results The Completed Runs Report from an Oncomine cfdna Assay run is similar to variantcaller plugin reports. The following outputs have been added. 1. After the run is complete, click Data4Completed Runs and Results, then click the Run Report for your results. 2. To view a summary of the variant analysis, scroll down to the variantcaller section, then click the appropriate button to download variant calls in.vcf or.xls formats.

6 1 Chapter 1 VariantCaller Plugin variant analysis Review Oncomine cfdna assay run results 3. Review the results in the Median Read Cov, Median Mol Cov, and Targets > 0.8MM columns. Column Median Read Coverage Targets >0.8 Median Molecular Coverage Median Read Coverage and Targets >0.8 Median Molecular Coverage Median Molecular Coverage Description Reports median coverage across targets. Median Molecular Coverage reports median number of individual interrogated DNA molecules across targets. Reports percent of targets with molecular coverage within 80% of the median coverage value. This is a new stricter definition of panel uniformity. Measures the quality of the sequencing run and library performance, while Median Molecular Coverage measures the amount and quality of the input DNA sample. Directly influences the limit of detection in a sample run. We always require two independent molecular families to identify a variant for it to be called. Lower median molecular coverage values result in less sensitive detection of variants at 0.1% frequency, although still sufficient for sensitive detection of variants with higher frequency. For example, Median Molecular Coverage of 700 is sufficient for accurate detection of variants at 0.5% frequency. For sensitive variant detection down to 0.1% frequency, we see optimal results when targeting a Median Read Coverage >25,000, Median Molecular Coverage > 2,500, and Targets >0.8 Median Molecular Coverage >60%. 4. Click a Barcode Name of interest to review Variant Calls by Allele. By default only hotspot alleles calls are shown in the variant table. We do not report hotspot alleles that did not meet our criteria for calling. However, we do provide at least one record for each hotspot position. This can include: novel allele call at hotspot position, hotspot allele call, or absent call when the first two are missing. 6 Oncomine cfdna Assays, Part III: Variant Analysis User Guide

7 Chapter 1 VariantCaller Plugin variant analysis Review Oncomine cfdna assay run results 1 Frequency LOD Column Description Reports the observed frequency of hotspot allele. Reports limit of detection at hotspot position, which is based on the number of interrogated DNA molecules (fragments) containing target. We use the term 0.1% LOD to mean we have data to support specific sensitivity and specificity claims (90% and 98%) at the 0.1% allelic frequency. By default, our analysis tool uses minimum alternative allele frequency threshold of 0.05% and we have a technical lower limit of detection of 0.03% for this method. Observed frequency can be lower than LOD due to sampling nature of the assay. If selected to display hotspot positions with absent variant call, then only one record per hotspot position is displayed and only one of the hotspot alleles at that position is displayed under "Allele Name". 5. Click View Coverage Metrics to view the total number of interrogated DNA molecules at hotspot positions (Molecular Coverage), and the number of molecules containing the variant (Allele Mol Cov). 6. You can modify the types of calls that are displayed in the Allele Calls dropdown list, by selecting or deselecting Absent, Heterozygous, Homozygous, or No Call. No calls are variant calls that are classified as systematic errors. Oncomine cfdna Assays, Part III: Variant Analysis User Guide 7

8 1 Chapter 1 VariantCaller Plugin variant analysis Review Oncomine cfdna assay run results 7. Select Absent in the Allele Call dropdown list to visualize hotspot positions without a valid variant call that meets our analysis criteria. We report one record per hotspot position with missing alternative call, and the alternative allele is an arbitrary value distinct from reference. LOD and molecular coverage metrics at those positions are measurements for variant absence among many interrogated molecules. 8. To view novel alleles, select Novel (sequenced allele that is different from the expected allele defined in the panel hotspot file) in the Allele Source dropdown list. 8 Oncomine cfdna Assays, Part III: Variant Analysis User Guide

9 2 Ion Reporter Variant Analysis Analysis workflows in Ion Reporter software Analysis workflows available in Ion Reporter Software include: Analysis Workflow Description Oncomine Lung/Colon/Breast Liquid Biopsy - w1.1 - DNA -Single Sample Detects and annotates low frequency (to 0.1% limit of detection) variants (SNPs, InDels) from targeted DNA libraries from the Oncomine cfdna Assay. This is compatible with DNA purified from cell-free DNA. Oncomine Lung/Colon/Breast Tumor - w1.1 - DNA -Single Sample Detects and annotates low frequency (to 0.5% limit of detection) variants (SNPs, InDels) from targeted DNA libraries from the Oncomine cfdna Assay. Due to deamination events caused by the FFPE process, the minimum alternative allele frequency is set to 0.3%. This makes it compatible with DNA purified from FFPE tumor tissue as well as fresh frozen tumor tissue. In Torrent Suite Software, you can plan your run to automatically transfer data to the appropriate Ion Reporter server and be analyzed through one of the Oncomine Lung workflows. View results and determine variants of interest Ion Reporter Software analyses are performed automatically on uploading of the data files from the Torrent Suite Software. To view the results: 1.

11 Chapter 2 Ion Reporter Variant Analysis View results and determine variants of interest 2 6. In the Liquid Biopsy column, view Mol Depth, Mol Counts, and other columns. Column Molecular Depth Molecular Counts Description Reports number of interrogated DNA molecules containing target. It defines limit of detection at hotspot position in a particular run and sample. For instance, if molecular depth is 1,500, you can have high confidence that no variant is present at 0.2%. If molecular depth is 2,500, you can have high confidence that no variant is present down to 0.1% LOD. For reference calls, Molecular Depth provides measurable metric that serves as confirmation for variant absence among a large number of interrogated molecules. Reports the number of detected DNA molecules containing variant allele. Oncomine cfdna Assays, Part III: Variant Analysis User Guide 11
