| Patches | Date |
|---|---|
AI rank is now available in a sortable, exportable column in the analysis tools.
Emedgene does not provide the AI score as it can bias the analysis; whereas AI rank provides an unbiased method to utilize AI in the interpretation workflow.
If two variants share an identical score they will have the same rank in the column.
A reanalysis will update the AI rank values.
Note: The AI feature was previously called ‘auto analysis’ and has now been renamed ‘AI shortlist’ in the versions tab and when editing the case.
( i ) Requires workbench & pipeline update. Old cases can be rerun to retrieve the rank.
Phenomeld score is now available in a sortable, exportable column in the analysis tools, in addition to the available filter. Range is 0-2.
( i ) Requires workbench & pipeline update.
As a reminder, Phenomeld is a proprietary phenotypic match algorithm that estimates the concordance between patient phenotypes and an associated disease. It is an important component in our XAI model.
Phenomeld achieves an AUC of 0.94, and uses ensemble machine learning, which combines several phenotypic match models in order to improve model performance.
The Phenomeld model was validated with two data sets.
Utilizing an internal dataset of 314 well characterized cases, Phenomeld was compared to the open source phen2gene model, as well as to the previous Emedgene Phenomatch model, outperforming both.
A second validation used a set of 4648 ClinVar cases, and compared Phenomeld with phen2gene, where Phenomeld demonstrated improved results.
This version improves support for labs that regularly apply multiple gene lists per case.
When applying a gene list at case creation, you can now create a new gene list comprised of multiple gene lists, or add genes to an existing gene list. The new ‘merged’ gene list will carry the same behavior as any other gene list on the platform.
Choose create a new gene list during add new case. Then, search for a single or multiple gene lists, or add genes to an existing gene list:
( i ) Requires a workbench update.
Customers can now dynamically couple a gene list, multiple gene lists, or any other search with their preset filters, and review the restricted subset of preset filters with full traceability. This enhancement addresses the need for users to track the reviewing of different gene lists in their case.
To increase flexibility of analysis, this feature is enabled using the search bar, which is now located above the preset filters.
Simply search for a gene list, multiple gene lists or any other supported search function.
By clicking on the 3 vertical dots, you can save your search as a custom preset filter. If you do not save a custom preset filter, you can still perform the restricted analysis, however it will not be saved, and you will not be able to populate it to a report.
You can then review the case according to any of your saved custom preset filters.
Custom preset filters are saved per case, have a full activity trail and can be automatically populated to a report.
( i ) Requires a workbench update.
Limitations:
Combining gene lists in Add New Case is not available from the API or batch upload.
When creating a new gene list by combining gene lists or other, the maximum number of allowed genes is 10,000.
A maximum of 10 custom preset filters can be created per case.
The cases page is getting two of the most requested updates in this version.
Lab directors can now assign cases to users, streamlining workload management within the lab. Previously only users could subscribe to a case.
( i ) Requires a workbench update.
The case quality summary has been added as a column in the cases page. This quick view of case quality will improve workload allocation within the lab. The column is sortable and can also be filtered on.
Hovering on the quality icon will provide a quick summary of findings, indicating failure for case or sample quality, and also pedigree and gene coverage validation.
( i ) Requires a pipeline & workbench update.
This version adds multiple features aimed at improving CNV interpretation capabilities, an effort that will continue in subsequent versions.
New visualization track = the target counts BigWig is now supported, in addition to the tangent normalized BigWig. This is a BigWig representation of the target counts bins. This new track is available from the UI, batch or API for customers starting from both FASTQ or VCF. ( i ) This feature requires both a pipeline and a workbench update.
Analysis tools – new column for variant length (kb), can be sorted, exported and populated to the report. ( i ) This feature requires a workbench update.
Analysis tools – New filtering capability by calling methodology. While this new feature applies to any variant caller used by customers, it can be used to create filters for CNVs called by the DRAGEN read-depth caller separately from the DRAGEN SV caller, so that customers can apply separate noise databases to each. The new filter appears under the Quality filters. Possible calling methodologies:
Small variant caller
CNV read-depth caller
Forced Genotyping
Star allele caller
STR repeat expansion caller
SV split-end caller
Targeted caller
Unknown
( i ) Requires a pipeline & workbench update.
Annotation is now enabled for CNVs larger than 20M bp. ( i ) Requires pipeline & workbench update
Visualization | Added the copy number value to CNV variants in the proband VCF track. ( i ) Requires pipeline & workbench update.
Visualization | Improved performance for the embedded IGV enables quickly moving between variants when multiple new visualization tracks are selected. ( i ) Requires a workbench update.
Limitations:
Variant Page | ACMG Classifications | Cannot be calculated for CNVs >20M bp.
Curate | Variant size limitation of 10M bp due to a live annotation speed limitation.
We continue to enable customers to control their Emedgene accounts, and to reduce their reliance on Illumina support teams.
Customers can now batch add variants to Curate via the UI, utilizing a simple CSV template. Emedgene software will perform a validation on the upload to ensure compatibility and quality in customer Curate databases.
Simply switch to batch mode in the Add new pane in Curate to download an example CSV file and follow the link for more instructions. Note the size limitation for each upload is 5,000 variants. Multiple concurrent uploads are allowed.
After upload, a ‘toaster’ element will appear at the bottom left of Curate. While the toaster can be closed and the upload will continue, the report on the variants uploaded and any that might have failed or partially failed validation can only be accessed through the toaster.
( i ) This feature requires a workbench update.
It’s easier than ever to create new gene lists in the Management page or Add New Case flow.
When switching to batch mode, both gene symbols and NCBI IDs are accepted.
When pasting a list of NCBI IDs or gene symbols from a CSV file, whether downloaded from an Emedgene staging organization or other, no further manipulation needed and the list is accepted as is.
( i ) This feature requires a workbench update.
We’ve made it easier to find and use our help center by moving it to help.emg.illumina.com no matter where you are located around the world. Previous local versions had limitations with internal linking, these are now fully removed. The new help center can be accessed at this URL regardless of workbench or pipeline versions.
Limitations:
For Curate batch upload, the maximum file size accepted is 10 MB or 5,000 variants. Customers can perform several concurrent batch uploads if needed.
Customers can navigate away from Curate while waiting for their file to import, however the activity ‘toaster’ will disappear, and no report will be available. A report can be requested from support teams.
Curate | Batch Upload | CNVs do not accept a transcript selection, but it is possible to push the column through in the UI batch upload.
Curate | Batch Upload | After correcting an error file, start a new upload to ingest the data. Re-upload buttons are not activated.
APIs | Upload of gene list comprised of only NCBI IDs is not possible via APIs, only through the UI.
This version adds multiple features that enhance flexibility to implement lab standard operating procedures.
Define a region of interest and QC BED for any test type, previously only customization for test type ‘Custom Panel’ was enabled.
The region of interest BED, whether default or custom, determines the billing.
If the number of variants annotated is <55K, billing is for a panel.
If the number of variants annotated is 55K-300K billing is for an exome.
If the number of variants is greater than 300K billing is for a genome.
If a reflex to a wider backbone is needed, the test can be edited and a different BED selected.
QC BEDs can be uploaded separately.
The Region of Interest and QC BED files can be defined from the Add New Case flow in the UI batch upload, and API.
( i ) Requires a pipeline & workbench update.
Many new QC metrics are now available in the Lab Tab through a DRAGEN report integration. If your DRAGEN report is available, a link will be added below the sample name. This feature is available for customers starting from FASTQ or VCF from API (See supported DRAGEN outputs below for details).
( i ) Requires a pipeline & workbench update.
Efficient API queries are here! When fetching details of variant(s) and case(s) via the API, users can now define which values to return, rather than returning all values associated with the query. Each query will return default values, and in addition the fields requested.
( i ) Requires a workbench update.
Support for custom BED annotations & filtering
Customers can now annotate their cases with a BED file, and filter on the variants based on the BED annotation. This feature requires support assistance for implementation.
( i ) Requires a pipeline & workbench update.
Push genes of insufficient coverage to a report
Customers can push lists of genes with insufficient coverage at various thresholds (<=0x, <=5x, <=10x, <=20x; or % of BasesGt20x <=20%, <=50%, <=80%, <=90%) and details (transcript, exons affected, position etc) to a report.
( i ) Requires a workbench update
This version expands the possible applications that can be interpreted and reported on in Emedgene to include haplotype driven applications.
This version expands the possible applications that can be interpreted and reported on in Emedgene to include haplotype driven applications.
Ingest and annotate the DRAGEN star allele caller JSON file (*.targeted.json) including targeted caller CYP2D6 and CYP2B6 outputs as haplotype variants.
New haplotype variant page displays haplotype, genes affected and quality parameters from DRAGEN.
Haplotype variants can be interpreted and pushed into a report.
Report pre-processing capabilities can be utilized to produce PGx reporting by integrating the customer’s own metabolizer status-drug database.
( i ) Requires a pipeline & workbench update.
Limitations:
This feature is only available for customers running DRAGEN in ICA, BSSH or server and starting cases from VCF.
gnomAD PLI scores were added to export csv. ( i ) Requires a workbench update.
ClinVar SV, ClinGen and MitoMap annotations were added to the monthly update automation infrastructure, and will be updated on a monthly basis going forward.
DRAGEN pedigree pipeline, which improves accuracy of de novo calling for WGS, is now available for customers starting from FASTQ. ( i ) Requires pipeline & workbench update.
Only for ICA customers with input FASTQs in ICA, who are only running WGS in their organization.
This feature has always been available for customers who run their own DRAGEN pipeline.
From the customer perspective, no experience with ICA needed and this behaves just like the integrated Emedgene DRAGEN pipeline, fully and seamlessly executed for customers.
Billing for DRAGEN runs is on ICA with iCredits. On Emedgene, please purchase the Genome Equivalents VCF SKU.
Customers starting from FASTQ will now run the DRAGEN 4.2 CNV-SV merged file by default. ( i ) Requires a pipeline update.
This version supports ingestion of outputs from Illumina’s newly released Trusight Whole Genome IVD workflow. ( i ) Requires a pipeline & workbench update.
This version supports ingestion of VCFs from Illumina’s CFTR IVD workflow. ( i ) Requires a pipeline and a workbench update.
This version supports ingestion of small variant calling VCFs from the Illumina amplicon pipeline. ( i ) Requires a pipeline & workbench update.
Supported DRAGEN 4.2 outputs in V35:
Add New Case | Input file path cannot contain spaces or parenthesis.
Add New Case | API | Applying multiple panels has a limit of 10,000 genes in total but no error message.
Add New Case | For customers starting from Joint gVCF, please make sure the proband is first in order to see the correct insufficient region calculation.
Pipeline | The DRAGEN pedigree pipeline for customers starting from FASTQ is only available for customers who have their FASTQ files stored on ICA, and only run WGS in their organization.
Edit Case | Reanalysis | When applying a new gene list the original gene list is not displayed in activity.
Lab Tab | Insufficient coverage export will not work via UI or API if an included gene does not have a start or end position in NCBI.
AI Shortlist | Will not prioritize chr17:43124027 ACT>A in the BRCA gene which contains >600K links to publications, due to limitations on annotation file size. This limitation will be removed in upcoming patch releases V34.4 and V35.1.
Analysis Tools | Multi-Select | Does not have an aggregated activity report.
Analysis Tools | Manually Added Variants | Cannot be sorted on non-applicable column types e.g. AI rank.
Analysis Tools | Manually Added Variants | STRs | Format is not aligned with format of STRs on the software, e.g. missing variant length.
Variant Page | Population data | ‘af_max_any_pop’ utilizes rounding to 5 digits.
Curate | When exporting a variant from Analyze to Curate, users may sometimes see an erroneous error message ‘None is not allowed for pathogenicity’. The actual error is an unsupported variant type.
Curate | Transcript versions will not be identical in variants created in Curate vs variants created in Analyze. Future enhancement will align transcript selection logic.
Curate | Discrepancy between Analyze and Curate HGVS parser may be experienced.
Network | GRCh37<-->GRCh38 Liftover not available for older components of Network infrastructure, as a result, [Variant Page | Clinical Significance | Networks Classified] may remain erroneously empty while [Variant page | Related cases section] shows relevant information. Same gap for manually classified variants.
Export to excel is limited to 32KB in size, which may prevent exports with very large CNVs.
Webhooks | Cannot be trigger on internal software statuses such as ‘In Progress’ ‘Reanalysis’.
Organization Settings | BED upload | Validation on the UI component does not check that all lines in the BED contain the same number of columns.
General | Users on Illumina clouds will now get a warning when they are logged out due to their IAM settings. The warning will prompt for a refresh, preventing loss of work on the Emedgene software. This issue was fixed in v34.2 patch and is re-documented with this release.
General | When there is a mismatch of the number of variants in the VCF and the number of variants in the case, a prominent red warning banner appears on the software. Prior to V35 this banner was organization-wide, flashing up for all users even with unaffected cases. Starting with this version, the warning will be case specific.
Candidate | Evidence Graph | Updated literature links to LitVar2.
Variant Page | Fixed an issue where in some cases OMIM inheritance modes were incorrectly displaying CGD values.
Analysis Tools | Fixed an issue that caused PLI filters relying on a ‘lof_intolerant_probability’ query to return partial results.
Curate | Fixed an issue causing display of Related Cases component for the previously displayed variant.
gnomAD 4.1 fix will be supported in V34.5/V35.1. All gnomAD 4.0 links from the UI are directed to 4.1 data, as there is no way to link directly to 4.0 data. This creates a data<-->link discrepancy as Emedgene annotation data is still on gnomAD 4.0.
Add New Case | Flow to run case as a singleton and add family members in a rerun is temporarily not working for cases starting from FASTQ. Targeted fix for V34.4 & V35.1.
Add New Case | API | When sending due date please use UTC time, customer time zone is not taken into account with API, only through the UI.
Edit Case | Reanalysis | If HPO terms were updated between analyses, the reanalysis will not automatically map previous HPO terms to new ones.
Cases Page | Illumina Clouds | Users that have been removed from workgroups in IAM can still be added as participants to a case. They will not have access to the software, and there is no security/access risk.
Candidates Page | Compound het SNV-CNV variants will not display the automated CNV classification. Workaround – view variants from analysis table.
Lab Tab | Average coverage calculation in the UI can miscalculated and over 100% in rare cases. Targeted fix for V34.5 and V35.1.
Lab Tab | UI issue makes it difficult to identify which sample is selected for viewing quality metrics. Fix planned for V34.5/V35.1.
Analysis Tools | ‘Last’ button on pagination does not work.
Variant Page | Rare lag in variant interpretation load time can cause text to be mistakenly overwritten.
Variant Page | Visualization | Simple/Advanced selectors will not work for locally uploaded BAM files.
Curate | Searching for a variant causes the related cases to disappear even when search is removed. Work around is to refresh.
Curate | Orphanet links no longer work due to an Orphanet link structure update.
Finalized Case | When user enters a variant in a case in finalized status, variant will be marked as viewed. Fix planned for V35.1.
Activity | Editing interpretation paragraph yields an erroneous activity labeled reanalysis.
API | Marking over 5000 variants as viewed will not result in an error message, although this is the database limitation for saving viewed variants.
Dashboard | Diagnostic Yield includes Uncertain as Resolved.

| Patches | Date |
|---|---|
Add New Case | Fixed an issue that caused Pending Sequencing workflows to fail in V35.
Edit Case | Fixed a bug that prevented saving and running edited cases that were opened on versions <V35.
Pipeline | Fixed an issue causing more frequent case failures in V35 due to incorrect infrastructure assignment to cases where BED selection for region of interest is larger than expected.
Analysis Tools and Report/Export | V35.0 added support for large CNVs (over 20M bp). This caused ‘case incompatible’ errors for some CNV filters and in exporting/reporting. This hotfix fixes both issues.
Curate | Batch upload – Fixed a bug that resulted in variants added to Curate via the batch uploader to only be available in the original reference, instead of in both with liftover-on-the-fly.
User Access | Fixed a bug causing users belonging to several domains to lose their roles when switching between domains.
Propagations of fixes from v34.6 and v34.7 including the ability to update an organization to gnomAD 4.1 non-UKB data for SNVs/indels.
Edit Case | Fixed a bug preventing a rerun of cases when original files are no longer available on BSSH.
Pipeline | Expanded RNA disease associated gene list in transcript selection logic. The genes added to the exception list are:

RNU4-2 RNA, U4 small nuclear 2
Pipeline: Multiple fixes to improve pipeline robustness and reduce failure rates.
Lab Tab | Fixed a bug resulting in no data loaded to the lab tab for new organizations.
Analysis Tools | Filters | Fixed a bug for Variant Effect Filters, when moving from simple to advanced, not all variant effects were available for filtering, which also caused a variant count discrepancy.
Analysis Tools | Preset Filters | Fixed a bug that always showed the description of removing polymorphic variants as ‘Display polymorphism: True’ although the behavior of the filter correctly removed the variants.
Variant Page | Embedded IGV | Improved IGV performance by reducing API calls when moving between variants.
Variant Page | Embedded IGV | Option to toggle embedded IGV off to improve performance for customers using external visualization tools.
Export | Fixed a bug failing the export of parental data for some customers.
Edit Case | Fixed an issue that could prevent reanalysis of cases that were created via API and were missing fields required in v35.
Cases Page | Fixed a rarely occurring issue where cases can be displayed with the good quality green icon even though they contain an insufficient coverage warning.
Analysis Tools | Filters | Fix an issue that caused frameshift indels to disappear from variant table when moving between simple and advanced mode in the quality filters.
Curate | Batch upload enhancement that will ensure all characters uploaded to Curate are supported in Analyze.
Curate | Curate now supports MNVs that are supported in Analyze, which are MNV indels only.
