A new card containing curated data from ClinGen variants database is now available in VarSome and VarSome Clinical.
This information will be available when the queried variant has already been curated by any of the ClinGen expert panels. It will display crucial information such as curated pathogenicity, associated phenotypes, and comments submitted by curators.
Analyses are now scanned for the presence of extended regions of homozygosity. Summary ROH data are displayed in Sample/Analysis Information, including percentage of autozygosity FROH, which is computed for several length thresholds.
An additional solution for CNV calling is available for WGS sample cohorts. The tried-and-tested read-depth method, which is already in use for WES and panel samples, offers improved recall of long CNVs complemented by concise and intuitive visualizations. The standard Delly-based solution remains available for single WGS samples.
To use this approach, select multiple WGS samples on the CNV launch analysis page and launch the analysis using them.
Important: please see the VarSome 11.4 release note for the full list of ACMG changes that are now fully integrated into VarSome Clinical.
On the Sample page we have now added 3 new options for deleting samples:
We have provided the option to run Multi-Sample analysis for somatic samples from a VCF.
For example, any trio analysis samples you have will now appear in the launch screen as an option for selection.
A new dynamic filter option has been added that provides the option to keep or filter out variants where their related gene has no associated OMIM phenotype
Currently we only report on a sample’s phenotypes that are associated with a variant’s gene. This is displayed in the Phenotype column. We have now provided the option to filter variants linked to a given number of matched phenotypes.
Additional VUS categories have been added to the pathogenicity class dynamic filter.
The Gene list search has been simplified so it is easier to make a search through the gene list filters.
It is now possible to complete a standard online form to request the creation of a new assay.
The submitted form will be reviewed by our support team.
Alternatively:
We have added to the dashboard the 'Total' and 'Monthly' number of samples analyzed.
The option to analyze WGS tumor/normal CNVs has been reintroduced. To run this option, on the CNV launch analysis page select both, one tumor normal and one normal sample and launch the analysis using them both.
JAX CKB have recently announced several new features that we have been quick to incorporate - this is a licensed database and only available to users for VarSome Clinical.
On the gene results page, within the JAX CKB information, a new table has been provided that presents all relevant clinical trials from Germany, Spain, Italy, France, Austria and Belgium but not the US or Canada. The clinical trials are all curated from clinicaltrials.gov. The table can be searched using the title, phase, recruitment status or NCID code.
Improved base quality recalibration for amplicon kitsWe have modified our amplicon analysis pipeline to use GATK recalibration tool (BaseRecalibrator) to allow detection of variants that were previously missed because they failed to pass the average base quality cutoff value. In some cases, such variants will still be labeled as failed, in which case the users can find them by checking 'Variant list will contain all variants' while launching a new analysis.
