How VarSome Clinical works?

Upload FASTQ or VCF

VarSome Clinical accepts FASTQ and VCF files. You can upload the data easily and securely through its web interface or you can harness VarSome's powerful API for an automated and secure data transfer. Once the data are uploaded, you can start the analysis!

Annotation & Classification

VarSome Clinical's robust pipeline is capable of analyzing whole genomes, exomes, and gene panels, for individual samples, trios, families, and cohorts in minutes. VarSome Clinical leverages the massive cross-referenced knowledge base of the free VarSome and offers also access to licensed databases.

Intuitive Web Portal

VarSome Clinical's feature-rich and intuitive web interface allows filtering variants according to pathogenicity, ACMG classification, allele frequency, gene list or phenotype, to name a few! Dynamic and algorithmic filters allow you to perform simple or advanced filtering, like segregation analysis, identification of de novo variants or variants in imprinted genes, and much more!

Clinical Report Generation

Once you have narrowed down the list of variants of interest, you can proceed with the generation of the clinical report, which includes all the details of your variants, including literature references and your custom comments. The layout of the report can be fully customized according to your unique branding policy.


End-to-End Solution

VarSome Clinical provides validated and clinically certified genome-scale variant discovery, annotation and classification.

Programming Interface

VarSome Clinical comes with a powerful API for automated data transfer in both directions - upload data and download annotated variants.

  • Precision Contests

    VarSome Clinical's variant discovery rocks! It received top marks in the recent contest organized by the Food and Drug Administration, and it was steadily in the top ranks in all metrics, as in previous precision FDA contests. These results are a testament to the VarSome team's total commitment to excellence. Check out our blog for more details.

  • Variant Discovery

    VarSome Clinical's variant discovery pipelines have been designed to achieve high-quality standards, such as reproducibility, sensitivity and precision:

    • Sensitivity: 99.8% for SNVs and 99.5% for indels
    • Precision: 99.8% for SNVs and indels
  • Experts in Big Data

    To date VarSome has aggregated and cross-referenced over 30 leading databases and other data resources, representing over 33 billion data points, and new ones are added constantly over time. But there is more to it: whenever a data resource is updated, VarSome quickly makes it available for annotation and classification of your variants! 

  • Network of Geneticists

    As VarSome Clinical has been deployed by dozens of institutional customers across many countries, you can benefit from VarSome's extensive network of molecular geneticists and health care professionals who contribute to the identification of likely causal variants, along with a summary of available therapeutic options.
