Rapid large-scale review of primers, probes, and genomic assay oligonucleotides using current GRCh38 and gnomAD population resources.
Resonance Genomics provides oligonucleotide QC support and assay-review workflows for large-scale evaluation of genomic oligonucleotides, including PCR primers, MLPA probes, hybridization probes, targeted sequencing assay oligonucleotides, and related genomic assay components. Workflows are designed to support review of hundreds to thousands of oligonucleotides in a standardized and scalable manner.
Workflows use current GRCh38 and gnomAD resources to identify population-variant overlap, assess sequence-context risks, review transcript-aware genomic positioning, and prioritize oligonucleotides for manual laboratory review.
The objective is not to replace laboratory validation, but to provide a scalable pre-screening layer that helps focus review efforts on oligonucleotides with characteristics that may warrant additional evaluation.
Structured review projects are performed on a per-project basis. Many oligonucleotide review projects can be completed within days of receiving finalized sequence files, depending on project scope and assay volume.
Workflow Features
- Large-scale oligonucleotide review against current GRCh38-aligned gnomAD population releases
- Review of population variants that may contribute to allele dropout,
- amplification bias, reduced assay sensitivity, or altered probe binding.
- 3′ terminal risk evaluation for amplification-sensitive primer-binding positions
- Transcript-aware target context and coordinate organization relative to current transcript frameworks
- Review of genomic mapping specificity and homologous-region alignment context
- Structured laboratory-oriented review outputs designed to complement existing assay evaluation workflows
Why Population-Aware Oligonucleotide Review Matters
As laboratories transition toward GRCh38-based workflows and newer population-frequency resources, additional variants may become visible within oligonucleotide binding regions. Reviewing these overlaps manually across large oligonucleotide collections can require substantial assessment effort, particularly when evaluating variants near amplification-sensitive positions.
Oligonucleotide-binding variants located near the 3′ terminus may disproportionately affect amplification performance, allele balance, or assay sensitivity in some genomic contexts. RG oligonucleotide QC is designed as a rapid pre-screening workflow to help laboratories focus manual review on oligonucleotide with potentially relevant binding-region variation, while allowing existing internal QC and assay validation workflows to remain in place.
Structured Review Outputs
- Primer-level flags for population variant overlap within binding regions
- Closest 3′-terminal variant distance assessment
- Risk indicators for variants near amplification-sensitive primer positions
- Review metrics for genomic mapping specificity and homologous-region context
- Indicators of segmental duplication or repetitive-region overlap
- Transcript-aware coordinate organization and target-context review
- Structured tabular outputs suitable for integration into existing laboratory QC and assay-review workflows
- Research-use support workflow. Final assay validation and laboratory QC decisions remain under laboratory control.
- Distance assessment from both 5′ and 3′ termini of overlapping variants

Research Use Statement
These workflows are intended for research-use and internal laboratory review support only. Outputs are not designed for diagnostic reporting or independent clinical decision-making.
Resonance Genomics provides research-use support for laboratories performing large-scale genomic oligonucleotide review, population-variant overlap analysis, sequence-context assessment, and assay-risk evaluation. Final validation and implementation decisions remain under laboratory control.
