What's new?

We are very excited to announce the release of DVD v8.2.1! With this release, we keep our list of genes consistent with the newest version of our OtoSCOPE® genetic testing platform. Coming Soon: update to all data sources that could impact classifications!

Version 8.2.1 changes

  • Expanded Variant List Filtering and Download Capabilities

    We have expanded the filtering capabilities for variant lists on the gene pages and variant search pages. Additionally, variant lists, filtered or unfiltered, may be downloaded in csv or json file formats. For more information on how to use these new features, please review our How to use this site page.

  • Gene Page Genome Browser

    Among many other functions, we have added the ability to add tracks based on variants in the variant table on gene pages. Also, a VCF file can now be uploaded as a track into the Genome Browser. For more information, please review the Genome Browser Functionality section of our How to use this site page.

  • Interactive CADD Phred Score Box and Whisper Plots

    After loading a variant table on a gene page, there is now the option to view a CADD Phred score Box and Whisker Plot, grouped by Pathogenicity classification, for all variants within that gene's regions. For more information, please review the CADD Phred Score Box and Whisker Plots section of our How to use this site page.

  • gnomAD v2.1.1 Annotations

    We now provide gnomAD v2.1.1 annotations as informative only (i.e. not classification impacting) data. We focus our efforts toward primarily coding regions and, for that reason, we have decided to annotate with v2.1.1 information instead of v3. For more information on gnomAD v2.1.1 vs v3, please see the gnomAD website.

  • Shearer et al. 2014 Population is no longer classification impacting

    The Shearer et al. 2014 (aka. the DVD's OtoSCOPE) population is no longer classification impacting as more recent sources provide better estimates of population frequencies. The Shearer et al. 2014 information is still available on variant pages for informational purposes.

  • Additional VEP Annotations

    We have expanded our use of VEP annotations to include information such as Interpro Domain and Motif data. For more information, please see the Variant Page and Variant Table sections of our How to use this site page.

  • More Efficient and Expanded Max MAF Organization on Variant Pages

    We have reorganized the way we display Max MAF population sources on Variant pages. Populations within each source are sorted with the greatest max MAF being the top-left most population and the least max MAF at the bottom-right. For sources with sub-population information, sub-population groups are sorted from top to bottom, greatest max MAF to least max MAF. Additionally, we provide homozygote alternate allele counts for sources that supply such information. For more information, please see the Variant Table sections of our How to use this site page.

Version 8.2 changes

  • VEP Annotations

    Ensembl's VEP has replaced ASAP for all variant annotations. This resolves descrepancies from ASAP's atypical InDel formatting as well as providing additional information for review on gene variant lists and on variant pages.

    For more information on VEP please see Ensembl's website.

    Note: We gather SIFT and PolyPhen-2 scores from both VEP and dbNSFP. In the event that both VEP and dbNSFP provide scores for a variant, VEP's SIFT and PolyPhen-2 scores override those of dbNSFP as a factor in our variant pathogenicity classification.

  • GnomAD Information Integration:

    GnomAD 2.0 variant frequencies are now available when viewing variant information. Please note that this data does not contribute to variant pathogenicity classifications and is provided for informational purposes only. GnomAD integration into pathogenicity classification is coming soon!

    Ashkenazi Jewish (ASJ) populations were excluded from MAF influenced variant classification.

  • CADD Information Integration:

    CADD phred score information is now available when viewing variant information. Please note that this data does not contribute to variant pathogenicity classifications and is provided for informational purposes only. CADD phred-like score integration into pathogencity classification is coming soon!

  • More variants have been manually-curated by the MORL
  • Variant Search Functionality

    There is now a variant search bar at the top of DVD webpages enabling the search of a specific variant, variants at a position, and/or variants in between a range of positions. The search bar is supported by an api interface as well. For more information about our api please see our API Documentation page. For more information about the search bar, please see our Help page.

  • Genome Browser

    A genome browser is now provided on gene pages for viewing gene level information in a track format.

    For more information regarding the genome browser plugin, please see BioDalliance's webpage.

  • Variant View Population Bolds and Highlights

    See the Population Maximum Minor Allele Frequencies (MAFs) and Their Sources section for more information.

  • Protein Structures via Force Field X (FFX)

    Protein structures are now provided on gene pages where available. These structures were modeled using Force Field X, an atomic resolution molecular modeling application.

    A promising source of evidence for classifying genetic variants is atomic resolution physics-based simulation techniques, which can test physical hypotheses about pathogenic mechanisms more rapidly and at a lower cost than many experimental approaches (e.g. model organisms). However, protein structural models (e.g. from X-ray crystallography, NMR, or homology modeling) required for simulation of hearing-related proteins are often based on imperfect experimental information (e.g. low-resolution diffraction) or may contain defects due to limited homology. We combine an advanced polarizable potential energy function, novel many-body optimization theory, and GPU-acceleration to locally and globally optimize all available deafness-associated protein models through the Force Field X (FFX) software program 1, 2, 3 . To objectively assess our models, we employed the MolProbity 4, 5 algorithm, which is widely used by crystallographers to aid refinement of models by reporting structural features that are known to be unphysical. Our optimization techniques improved the mean MolProbity score of 472 structures from 2.16 Å to 1.04 Å, consistent with protein structural models that approach atomic resolution.
