Hybridization Capture-Based NGS Panel

CD-Genomics is a company with rich experience in targeted gene panel sequencing which is used to accurately detect gene variations related to diseases.

CD-Genomics provides custom NGS panels for mutations in at least 68 diseases and thousands of genes. We can employ two target enrichment strategies prior to the NGS panel, which are amplification and hybridization capture. In a hybridization capture strategy, the ‘capture’ can be realized through the hybridization of fragmented DNA with baits complementary to regions of interest, either on a microarray chip or free in solution. In-solution hybridization capture can be scalable and easily automatable and rules out the shortcomings of microarray hybridization such as high cost, limitations to the number of samples and large sample requirements. Thus, solution-based hybridization becomes the mainstream approach of capture-based enrichment for NGS panel.

Highlight Applications

For larger disease panels

Disease-related gene discovery

Rare disease-related variant detection

Widely used in oncology research, inherited disease research, and more

Hybridization Capture-Based Disease Panel Workflow

Hybridization Capture-Based Disease Panel Workflow

In a hybridization assay, the protocols start with random shearing of the genes, which are later denatured by heating. Randomly sheared overlapping fragments are captured by DNA or RNA single-stranded oligonucleotides specific to the region of interest. DNA bound to the baits is separated from background DNA. The baits are removed and DNA enriched for regions of interest is taken forward to the second round of PCR, followed by NGS of the enriched nucleic acids.

Our strict quality control throughout the pipeline workflow to ensure the accuracy and repeatability of the enrichment, sequencing and bioinformatics analysis of hybridization capture-based NGS panel.

Bioinformatics Analysis

Analysis Contents Details
Bait design The design of nucleic acid baits for hybridization capture.
Primary analysis To identify single nucleotide variants and small insertions/deletions.
Trimming pipeline Quality control check is implemented and only samples with enough reads and base quality are considered
Variant identification & annotation Mutations are considered pathogenic if they are absent from controls, predicted to alter the sequence of the encoded protein and to adversely affect protein function.
Allelic variant profiling To detect and characterize complex allelic variants, such as short tandem repeats.
Variant classification To detect mutations at low-allelic fraction from sequencing of matched tumor-normal sample pairs.
