Major new version released, version 10

=============

You can also view this on the web at: http://decipher.sanger.ac.uk/about/news

 

In this major release, it is now possible to deposit, interpret and share, sequence variants, copy-number variants, aneuploidy/segmental aneuploidy, uniparental disomy, short tandem repeats, inversions and insertions (including mobile element and retrogene insertions). All variants for a patient are shown in a single genotype table. In this example, the patient has two copy-number variants and one sequence variant: https://decipher.sanger.ac.uk/patient/262947/genotype. Variant interpretation interfaces are available for each variant class to assist diagnosis. It is also no longer essential to provide a transcript when depositing sequence variants, to aid in the interpretation of the non-coding genome.

 

To represent the complexity of rare disease genetics, it is now possible to group variants to represent, for example, compound heterozygous variants or rare pathogenic haplotypes. In this example, two heterozygous NEB variants are grouped to show that the variants are in trans: https://decipher.sanger.ac.uk/patient/276998/genotype. This grouping information is shown on the patient record and also in search results (https://decipher.sanger.ac.uk/search/patients/results?q=neb) and the matching patient interface (https://decipher.sanger.ac.uk/patient/276998/genotype/205256/patient-overlap/snvs).

 

A new functionally identical variant interface is now available, which allows the easily visualisation and comparison of patient variant/phenotype data, for patients with the same variant. In this example, the functionally identical variant interface is shown for a patient with a recurrent PACS1 variant: https://decipher.sanger.ac.uk/patient/304548/genotype/200531/patient-overlap/identical

 

The protein browser now has additional features. DECIPHER splice region variants are now displayed assisting interpretation of this class of variant. In this example, splice region variants can be seen in the STXBP1 protein: https://decipher.sanger.ac.uk/gene/STXBP1/overview/protein-info. To further aid variant interpretation, exon phase has also been added to the exon information popup, and a DECIPHER variant inheritance filter has been added. The inheritance filter makes it possible to display only de novo or inherited variants and can be accessed from “Settings” at the top of the browser.

 

To assist in identify genes that may be causing a patients phenotype, the gene table now displays the DDG2P category and mode, as can be seen for this patient with a CNV on chromosome 22:  https://decipher.sanger.ac.uk/patient/398458/genotype/177559/genes

 

The DECIPHER help page has been updated to assist you with the new features. This includes links to short YouTube tutorials. The help page can be viewed here: https://decipher.sanger.ac.uk/about/help

 

 

Features currently unavailable

=============

The phenotype browser and bulk upload are not available for a short period to allow the DECIPHER team to finalise these features in the new interface.

The new bulk upload will support all variant classes, therefore the bulk upload templates will change considerably. If this change will affect how your centre deposits data and you would like to discuss this, please contact DECIPHER. The new bulk upload will also support the deposition of sequence variant ACMG criteria, in addition to phenotype manifestations. There will be a deposition API in version 10, please contact DECIPHER if you are interested in using this API.

The variant following feature is not available in DECIPHER version 10. If this is a feature that you have found useful, and would like a variant following feature in the new version of DECIPHER, please contact us to discuss your requirements.

 

 

Genome browser configuration

=============

Due to the introduction of new genome browser tracks for the new variant types, it is possible that tracks that you expect to be displayed will not be visible. If you encounter this issue, please use the reset tracks and configuration button (rotating arrow) on the right-hand side of the genome browser. A description of the genome browser controls can be viewed here: https://decipher.sanger.ac.uk/files/pdfs/DECIPHER_Genoverse_June_2020.

 

 

Internet Explorer 11 – please update your browser

=============

If you are using Internet Explorer 11 (IE11), not all features of the DECIPHER website will be displayed. We highly recommend using Google Chrome or Firefox for the best experience with the DECIPHER website. The following link provides information about how to update your browser: https://browser-update.org/en/update.html

 

 

Safari – please enable popups

=============

Please be aware that if you are using Safari, this browser blocks sites from opening content in a new tab by default. For the best experience with the DECIPHER website, please enable pop-ups.
