Focus on key target genes

Sequence genes of interest to high depth with predesigned or custom panels

Targeted Gene Sequencing

Targeted gene sequencing panels are useful tools for analyzing specific mutations in a given sample. Focused panels contain a select set of genes or gene regions that have known or suspected associations with the disease or phenotype under study. Gene panels can be purchased with preselected content or custom designed to include genomic regions of interest.

Next-generation sequencing (NGS) offers the scalability, speed, and resolution to evaluate targeted genes of interest. Multiple genes can be assessed across many samples in parallel, saving time and reducing costs associated with running multiple separate assays. Targeted gene sequencing also produces a smaller, more manageable data set compared to broader approaches such as whole-genome sequencing, making analysis easier.

Our Smallest, Most Accessible Sequencer

The iSeq 100 System offers affordable, fast, and accessible sequencing power for targeted or small genome sequencing in any lab.

Explore iSeq
  • Sequences key genes or regions of interest to high depth (500–1000× or higher), allowing identification of rare variants
  • Provides cost-effective findings for studies of disease-related genes
  • Delivers accurate, easy-to-interpret results, identifying variants at low allele frequencies (down to 5%)
  • Enables confident identification of causative novel or inherited mutations in a single assay

Predesigned panels contain important genes or gene regions associated with a disease or phenotype, selected from publications and expert guidance. By focusing on the genes most likely to be involved, these panels conserve resources and minimize data analysis considerations. Predesigned panels are available for research on various diseases, such as cancer, inherited disorders, cardiac conditions, and autism.

With custom designs, researchers can target regions of the genome relevant to their specific research interests. Custom targeted sequencing is ideal for examining genes in specific pathways, or for follow-up experiments from genome-wide association studies or whole-genome sequencing.

Illumina supports two methods for targeted sequencing: target enrichment and amplicon generation.

  • Target enrichment: Regions of interest are captured by hybridization to biotinylated probes and then isolated by magnetic pulldown. Target enrichment captures 20 kb–62 Mb regions, depending on the experimental design.
  • Amplicon sequencing: Regions of interest are amplified and purified using highly multiplexed oligo pools. This method allows researchers to sequence a few genes to hundreds of genes in a single run, depending on the library preparation kit used.

DesignStudio Software: An easy-to-use online software tool that provides dynamic feedback to optimize probe designs.

AmpliSeq for Illumina Custom Panels: Create custom targeted sequencing panels optimized for content of interest.

Nextera Rapid Capture Custom Enrichment Kit: Custom assay for enriching genomic regions of interest, with add-on functionality.

Benefits of Target Enrichment vs. Amplicon Sequencing
Target Enrichment
Amplicon Sequencing
Larger gene content, typically > 50 genes Smaller gene content, typically < 50 genes
More comprehensive profiling for all variant types Ideal for analyzing single nucleotide variants and insertions/deletions (indels)
More comprehensive method, but with longer hands-on time and turnaround time* More affordable, easier workflow

* the turnaround time is for library prep assay time (DNA to finished library).
