Whole-exome sequencing (WES) has been increasingly adopted into oncology testing and research to profile tumor samples. It can be used to guide treatment selection, identify emerging biomarkers and predict patient responses to immune checkpoint inhibitors.
Exome enrichment supports deeper coverage, cost effectiveness and improved variant calling. However, the complexity of sequencing data can present challenges for the analysis and interpretation of relevant clinical insights.
This whitepaper explores the latest reagents and software available to enhance tumor exome profiling for the generation of accurate, actionable clinical insights.

Agilent Integrated Whole-Exome Sequencing Solutions
Whole-exome sequencing (WES) is increasingly being adopted in oncology testing
and research to comprehensively profile tumor samples. WES is the gold standard
for determining tumor mutation burden (TMB), which is used to guide treatment
selection as TMB is an emerging predictive biomarker for response to immune
checkpoint inhibitors. In the field of recurrence monitoring, WES is used to identify
mutations in tumor samples in order to create individualized next-generation
sequencing (NGS) assays for monitoring minimal residual disease (MRD). WES is
also used to identify neoantigens in tumor immunotherapy research.
Agilent now provides a WES solution for cancer research labs that includes exome
enrichment reagents and software for variant analysis and interpretation. This
sequencing solution enables simultaneous detection of somatic single nucleotide
variants (SNVs), insertions/deletions (indels), and copy number variations (CNVs),
delivering a streamlined workflow with increased sensitivity to detect diseasecausing mutations.
The Agilent SureSelect Human All Exon V8 panel provides comprehensive coverage
of protein coding regions from RefSeq, CCDS, and GENCODE, as well as the TERT
promoter region. The exome panel, powered by machine learning-based probe design
and a new production process, delivers excellent enrichment performance, as well
as efficient and cost-effective exome sequencing. The exome panel can be easily
augmented to include customized content for specific applications. The exome
enrichment workflow is natively automated on the Agilent Magnis NGS prep and Bravo
Automated Liquid Handling systems for enhanced productivity in the laboratory.
Users can readily examine sequencing data using the Agilent Alissa Clinical
Informatics platform, an end-to-end exome sequencing solution for seamless and
efficient variant analysis, interpretation, and reporting. Raw data can be analyzed
with the Agilent Alissa Reporter software, an intuitive and streamlined cloud-based
NGS software-as-a-service (SaaS) solution that simultaneously detects SNVs, indels,
and CNVs. Users can easily navigate data with integrated genome browsing, a builtin quality control (QC) dashboard, and a seamless connection to the Agilent Alissa
Interpret software for variant interpretation and reporting.

Variant Analysis, Interpretation and Reporting
Figure 1. Agilent whole-exome sequencing solutions. The SureSelect human all exon V8 panel can be paired with the Agilent Bravo NGS workstation, Magnis
NGS prep system, and the Alissa Clinical Informatics platform to achieve operational efficiency. The exome is readily automated on the Bravo NGS workstation
for high-throughput applications. The Magnis human all exon V8 kit is pre-aliquoted for use on the Magnis NGS prep system, which requires only 10 minutes of
initial setup time and delivers eight exome-enriched libraries in less than nine hours without further operator intervention. The Alissa Clinical Informatics platform
allows clinical workflows to be streamlined from variant analysis to variant annotation, enabling genetics and molecular medicine labs to efficiently triage, curate,
and report genomic variants.
Figure 2. Alissa Reporter detects SNVs, indels, and CNVs from exome sequencing. The Alissa Reporter CNV detection module
detects both CNV amplifications and deletions, down to the gene level. CNVs are visualized in a sortable and filterable table. A
link to the detailed view is available from within the overview table, in which CNVs can visually be inspected using an integrated
genome browser (CNV viewer). A CNV amplification in gene ANKRD36C is shown.
Alissa Reporter for High-Performance Variant Detection
From a single genomic sample, researchers can get more valuable information than ever before. Alissa Reporter supports parallel
variant detection from somatic DNA specimens. With Alissa Reporter’s secondary analysis capabilities, you can detect SNVs,
indels, and CNVs (Figure 2). As a fully transparent solution, Alissa Reporter includes confidence scores next to CNV calls.

Built-In QC Dashboard for Operational Excellence
Alissa Reporter helps users quickly verify that an NGS assay is performing as planned. With the built-in QC dashboard (Figure 3),
users can immediately assess whether key QC metrics of individual samples (or the entire run) are within the anticipated range. Alissa
Reporter flags problematic samples and shows users where the QC metric has deviated from recommended values.
Alissa Reporter can track and display QC metrics longitudinally. By analyzing quality control data across runs, users can easily identify
trends and deviations from expected performance parameters over time.
Figure 4. The virtual gene panel option enables users to filter based on genes and/or regions of interest.
Figure 3. The Alissa Reporter QC dashboard helps you quickly find the metrics that matter most.
Virtual Gene and/or Regions Panels
If users are only interested in analyzing
a subset of genes or regions, the
Alissa Reporter in silico filter (Figure
4) enables the creation of virtual gene
panels. Create targeted gene panels
in advance based on your subpanels
of interest or edit your selected panel
when needed. It is easy to manage
in silico filters with Alissa Reporter’s
intuitive filtering functions. Simply
select or upload the gene(s) and/or
region(s) to be included, and Alissa
Reporter will automatically filter the
dataset based on this selection.

Somatic Variant Detection on the Mitochondrial Genome
The mitochondrial genome poses several challenges to the identification and understanding of somatic variants. Alissa
Reporter’s optimized SureSelect human all exon V8 and SureSelect custom panel pipelines come with a dedicated mitochondrial
DNA analysis option (Figure 5). The workflow enables labs to explore the state of mitochondria by enabling the detection of
mitochondrial variants (that is, SNVs) to identify heteroplasmy. Alissa Reporter delivers mitochondrial variant detection with high
sensitivity, helping labs to confidently identify biomarkers in metabolic disease research.
