Specialized Tools: Premium Annotations

Premium Annotations: Licensed Clinical & Research Databases

License the genomic knowledge bases your clinical reports cite. Premium add-ons bring Golden Helix CancerKB, OMIM, LOVD, CADD, Mastermind, and CI-SpliceAI into the VarSeq Suite for variant filtering, classification, and reporting.

The Foundation of Clinical Interpretation

High-quality genomic analysis is only as strong as the data that powers it. While public databases provide an essential starting point, clinical-grade workflows often require the depth and precision of expert-curated, licensed databases. Golden Helix licenses and integrates these premium sources so your reports cite current, expert-curated evidence.

Vetted & Curated

All databases are cleaned, standardized, and integrated for immediate use within VarSeq.

Monthly Updates

Monthly dataset refreshes keep ClinVar, gnomAD, OMIM, and other sources current.

Local Storage

All annotation data stays on your infrastructure, supporting reproducibility and compliance audits.

Expert Curated Content

Golden Helix CancerKB™

Golden Helix CancerKB is curated in-house by PhD scientists with cancer genomics and clinical backgrounds, drawing on primary literature, NCCN and WHO guidelines, and trial databases. It provides diagnostic, prognostic, and therapeutic interpretations, with deep coverage of somatic variants in hematological cancers.

  • Overhaul of diagnostic and prognostic interpretations for hematological cancers.

  • Integration of the latest NCCN and WHO guideline updates.

  • Automated identification and classification of somatic mutations in VSClinical.

Leading Clinical Partners

Direct licensing and integration for the databases clinical labs cite most: OMIM, LOVD, CADD, Mastermind, and Golden Helix CancerKB.

LOVD Add-on

The Leiden Open Variation Database is a federated network of expert-curated Locus-Specific Databases (LSDBs), with variant classifications, phenotypes, and functional evidence often missing from larger repositories.

  • 400,000+ unique variants & 10,000+ CNVs
  • Classifications, phenotypes & inheritance patterns
  • Functional evidence & literature citations

OMIM® Add-on

Online Mendelian Inheritance in Man provides curated summaries of gene-phenotype relationships and Mendelian disorders.

  • Phenotype-driven gene prioritization
  • Curated clinical synopses
  • Essential for HPO-based analysis

CADD Add-on

Combined Annotation Dependent Depletion (CADD) is a tool for scoring the deleteriousness of single nucleotide variants as well as insertion/deletion variants in the human genome.

  • Integrates diverse annotations into a single score
  • Prioritize functional non-coding variants
  • Vetted and optimized for VarSeq engine

200+ Annotation Sources, Vetted Monthly

Golden Helix maintains a catalog of 200+ public and premium datasets, vetted, cleaned, and optimized for the VarSeq annotation engine.

Frequently Asked Questions

How are premium annotations licensed?

Premium annotations like OMIM, Mastermind Curated Variants, and CancerKB are licensed as annual add-ons to your VarSeq subscription. Golden Helix handles the technical integration, data cleaning, and updates, providing you with a single point of contact for both the analysis software and the curated data sources.

How often are the databases updated?

Golden Helix provides monthly updates for all curated datasets. This ensures that you have access to the latest versions of public databases (like ClinVar and gnomAD) and the most recent releases of professional sources like OMIM and Mastermind, all vetted and standardized for our platform.

Can I use these annotations without an internet connection?

Yes. All annotation data is stored locally on your analysis workstation or server. This is a core requirement for many clinical labs to ensure reproducibility, data privacy, and performance independent of external service availability or cloud dependencies.
