Overview


The Lymphoma NGS Assay is a hybridization capture–based next-generation sequencing assay designed for comprehensive molecular profiling of lymphoid malignancies. The assay enables high-resolution detection of clinically relevant genomic alterations to support lymphoma subtype classification, prognostic stratification, and identification of actionable biomarkers for targeted therapy selection.

The Lymphoma NGS Assay combines DNA- and RNA-based analyses within a single workflow, supporting histopathological evaluation and facilitating precision diagnostics consistent with WHO and ICC lymphoma classification guidelines.

Lymphomas are driven by a heterogeneous spectrum of genomic alterations arising from aberrant somatic hypermutation, dysregulated antigen receptor signaling, epigenetic deregulation, and recurrent chromosomal rearrangements. Key oncogenic mechanisms include:

  • Alterations in B-cell and T-cell receptor signaling pathways
  • Activation of JAK/STAT and NF-κB signaling
  • Oncogenic gene fusions and structural rearrangements

Accurate detection of these molecular events is essential for lymphoma subclassification, prognostic assessment, and therapeutic decision-making. The Lymphoma NGS Assay is engineered to deliver uniform and sensitive coverage across biologically complex regions commonly implicated in lymphoid malignancies.

Assay Chemistry and Methodology


The assay employs a hybridization capture–based target enrichment strategy, engineered for efficient and uniform capture of complex genomic regions, including GC-rich, repetitive, and homologous sequences. An optimized hybridization time of approximately 4 hours enables rapid library preparation without compromising to capture specificity or depth of coverage.

The workflow is designed to be automation-friendly, supporting both manual and automated library preparation formats to accommodate varying laboratory throughput requirements. The assay demonstrates platform-agnostic compatibility and has been validated across commonly used sequencing systems, including Illumina, Element Biosciences, MGI, and Thermo Fisher platforms. This streamlined and flexible workflow ensures high reproducibility, consistent assay performance, and scalability across diverse clinical laboratory settings.

Bioinformatics & Data Analysis Pipeline


NGS data analysis is supported by GATK-based pipelines integrated with the Cliseq Interpreter Platform, a cloud-based clinical interpretation solution designed to streamline analysis of complex genomic data.

  • Quality control, alignment, and variant calling
  • Annotation of somatic variants using curated clinical databases
  • Identification of clinically significant mutations (CSMs)
  • Generation of downloadable annotated VCF files and CSM reports
  • Integration of therapy-linked insights, including FDA-approved drug associations where applicable

This integrated bioinformatics framework enables standardized, reproducible, and clinically actionable interpretation of lymphoma genomic data.

Assay Design & Gene Content


The Lymphoma NGS Assay is designed for comprehensive genomic coverage, encompassing 134 genes associated with DNA mutations, 21 DNA fusion genes, and 94 RNA fusion genes within a total target size of approximately 0.7 Mb. The assay covers entire coding sequences along with clinically relevant hotspot regions, enabling robust detection of disease-defining and actionable variants. This integrated assay architecture supports simultaneous interrogation of single nucleotide variants, small insertions and deletions, copy number variations, and both DNA- and RNA-based fusion events within a single, consolidated assay workflow.

Key features and highlights


  • Comprehensive Coverage: Targets key genes implicated in Hodgkin and non-Hodgkin lymphomas.
  • Diagnostic, Prognostic & Therapeutic Insight: Identifies mutations that inform diagnosis, predict outcomes, and support treatment decisions.
  • High Sensitivity: Detects low-frequency somatic variants for accurate disease profiling.
  • DNA & RNA Analysis: Enables detection of both gene mutations and fusion transcripts in a single assay.
  • Optimized for Clinical Use: Designed to support personalized medicine and evidence-based care in lymphoid malignancies.
