Variant Analysis Release Notes

Release 3.1.20140729

New Features/Fixes:

  • Users can now group suspect variants based on whether the variants occur in families rather than individuals. This option is available in the pair/matched section of the Genetic Analysis filter when pedigree is provided.
  • Users can now quickly search for samples matching terms present in annotation fields.

  • Users will be able to further refine their searches by nesting the search fields.
  • Update of the computed assessments and inferred sex algorithms.
  • There is now the option to disable auto-recalculate of the filter cascade after each adjustment is made. We think this new feature will save a lot of time and make iterative testing of filter combinations much faster.

Release 3.0.20140417

New Features/Fixes:

  • Analysis with 200 or less whole genome samples  can optionally be pre-filtered to only include intronic regions +/- 20bp flanking . This will result in faster time to results and more efficient use of resources.

Screen Shot 2014-04-18 at 10.00.46 AM

  • Computed assessments are now based on latest draft ACMG 2014 guidelines, including frameshifts in genes implicated in diseases where loss of function is a known mechanism of action. This may cause some variants which previously had uncertain significance to now be (likely) pathogenic and pass through Predicted Deleterious filters.
  • HGVS nomenclature refinements.
  • Normalization of INDEL display across file format.
  • Improved sample(s) and analysis status with end date, color indicator and filtering.

User-added image


Release 2.0.20130402

New Features/Fixes:

  • Easily re-use settings from another analysis to use the same filter cascade.
  • Include any custom annotations such as BED file(s) uploaded in the initial analysis or inheritance pattern selection.
  • Tentatively assign same case and control samples when creating a new analysis.

User-added image

  • The Legend now show the Confidence of a sample in lieu of the Call Quality.  For example in variant being present in each sample based on preceding Confidence Filter is now shown by dark (confident) versus light (not) color shading of Case and Control genotype icons

User-added image

  • Case (and Control) sample counts (and percentages) with variant now only include samples with Confident variant call in the Genes, Pathways, etc. summary tables.
  • The region into introns to consider for potential splice site mutations can now be increased from the canonical junctions (+/-2 nucleotides adjacent to exons) in the Predicted Deleterious filter. When enabled, intronic variants now are only counted as being in the gene by subsequent filters if they occur within this region to avoid counting overlapping genes.

User-added image

  • Now the HGVS Transcript Variant and Protein Variant columns include the coding and protein form qualifiers (c. and p. prefixes, respectively) to make the form explicit.

User-added image

  • A What’s New link will appears if there’s been a new product release since your last login. The Release Notes are also available from the online Help
  • The analysis Summary tab per-sample vertical stacked bar charts by value are now scaled by # variants (max across all samples) rather than % total variants within each sample. This better calls out visually if certain samples are skewed with many more variants than expected overall or for a particular value.

Release 2.0.20130314

New Features/Fixes:

  • Missense variants (majority of variants in a genome) can be selected for separately  from other types of (typically more deleterious) variants in Predicted Deleterious filter
  • PolyPhen-2 is now available to exclude variants it predicts are not functionally benign

User-added image

  • The gene details panel list for the Genes, Groups/Complexes, Pathways, Processes, and Diseases summary pages summarizes number of samples with variants in the gene for cases and controls as well as the inferred impact of the variants on the gene activities (loss, normal/carrier status, or gain of function).

User-added image

  • The click on a gene in the gene details panel jumps to Variants table with the gene in the search box to quickly see the corresponding variants
  • Summary tab now enables per-sample bar chart view of the values to quickly identify any outliers

User-added image

  • Exome server project data is distinguished between zero (no exomes with variant gets 0%) and no data, including in Common Variants filter.
  • Cytoband in Variant Details panel  is hyperlinked now to UCSC genome browser which enables quick access to multiple sequence alignments and chromosome and position details.

  • Variants that impact drug binding can now be selected with Pharmacogenetics filter
  • Pathway viewer enables Drug Targets to be highlighted
  • Symmetric gene and pathway burden test (C-Alpha)
