Adding an assay to VarSome Clinical

Learn how to upload your custom BED file.

VarSome Clinical customers

If you are a VarSome Clinical customer and your assay is not yet available in VarSome Clinical, we can add your assay if it is an assay we can support.

If you need us to add a new assay, the first question is whether this is a standard assay or if it requires special handling. Examples of special handling include but are not limited to assays with Unique Molecular Identifiers (UMIs), assays that are designed to produce mixed RNA and DNA sequencing data, assays targeting specific classes of variants such as certain large deletions in genes like CFTR and various other special cases. If you do not know if an assay requires any special treatment, please talk to your assay providers and ask them if any special bioinformatics approaches are required to handle the data the assay will be used to generate.

You can now request to add your assay of preference by filling the corresponding form which is available in the following link: https://ch.clinical.varsome.com/new-assay-request/.

On this form you will need to fill the requested fields:

  1. The assay's manufacturer name
  2. Whether it is a capture or amplicon-based assay
  3. The version of reference genome (hg19 or hg38)
  4. If the assay  includes Unique Molecular Identifiers (UMIs)
  5. The name of the assay to be shown on Varsome Clinical
  6. The type of files you are uploading (manifest, .bed or .bed and .bedpe)
  7. Choose the corresponding files
  8. Specify if any special bioinformatics approaches are required to handle the data the assay will be used to generate.

Please keep in mind that for assays targeting relatively small regions of the genome (i.e. assays that are neither whole-exome nor whole genome) variant calling will be performed in targeted mode, only looking at the regions mentioned in the assay.

Prospects evaluating VarSome Clinical during the free trial period

Unfortunately, we cannot add assays for free trial users. However, this should not be a problem. If your assay is not listed, you can choose the "Generic capture kit", for the case of capture-based libraries.


As long as you choose the right chemistry type as described above, the results will be the same as if we had added your assay. The only differences will be that we will not give you statistics about the percentage of reads that fall on target and we will not run the variant calling in targeted mode  (since we do not know the targets) so you may see variants that fall outside your regions of interest. However, the results will be correct and reliable.

If you finally decide to join us and become a VarSome Clinical customer, we will be happy to add your assay to our platform, as described above.
