Mutation Forecaster, a software resource for genome-scale analysis of complete genes and human genomes

Complete genome sequencing is now feasible, becoming cost effective, and increasingly an essential component of cancer discovery and patient genomic analyses. This has created a bottleneck in interpretation of gene variants, partly because the effects of most variants remain unknown (variants of unknown significance, VUS), and also because interpretation is confounded by the lack of corresponding genetic information from closely related family members.   The VUS problem is now exacerbated by the discovery of massive numbers of variants in each genome, many never before seen. Technologies that prune variants in an individual are essential to perform any large scale gene panel, exome or genome analysis.  The variant analysis approaches I will describe improves complete gene and genome sequence analyses and by detecting dysregulated biochemical pathways.  We stratify variants by mutation severity, which can suggesting or exclude particular therapeutic options (Shirley et al. 2013 <>; Dorman et al. 2014 <>; Mucaki et al. 2011 <>; Mucaki et al. 2013 <>, Viner et al. 2014 <>).Our patented software computes changes in information content in DNA or RNA sequences. These changes tell us which sequences disrupt the regulation of genes and how severe these changes are.   Our methods have been validated in hundreds of published studies (Caminsky et al. 2014 <>), and use proven information theory, one of the most important scientific advances of the last century. I will introduce a single system that amalgamates several of our software products, and which also queries existing public databases and store results for users. MutationForecaster <> provides basic capabilities offered by others, but also offers proven mutation interpretation  methods not available elsewhere. This leads to more comprehensive mutation results and ultimately, a more complete understanding of the dysregulation of disease genomes.

March 5, 2015. Interest in Mutation Forecaster™

Mar 5, 2015   //   by Peter Rogan   //   News  //  Comments Off

Since our release of the Mutation Forecaster system in January, we have been gratified to see the level of interest by the biomedical and clinical research communities. There have been 32 registrants from 18 countries.  One subscription has been activated, and others are in progress.

Our fees are reinvested to improve and expand this resource.  For example, we are developing a completely automated workflow for genome scale coding and splicing mutation analysis, and which will automatically prepare written report summaries. Our plans for this product will meet your future needs for mutation interpretation.

Cytognomix has released version 2.0.2 of the  Shannon splicing mutation pipeline for the Qiagen-CLCbio Genomics Workbench versions 7.5.2 and 8.0 and for  Genomics Server versions 6.5.3 and 7.0.  Please contact Qiagen-CLCbio to purchase a license to this software.

February 8, 2015. Early adoption of the MutationForecaster system

Feb 8, 2015   //   by Peter Rogan   //   News  //  Comments Off

Cytognomix is pleased to announce the sale of annual subscriptions of our MutationForecaster system to a molecular diagnostics laboratory at a public hospital in the Toronto metropolitan area in Ontario, Canada. The client is a long time paid subscriber of our ASSEDA product, who now has an express need for higher throughput software to handle results of next generation sequencing studies. MutationForecaster™  is the only efficient and accurate platform for comprehensive, on-demand coding and mRNA splicing mutation analysis on the market.

We find and validate mutations that others cannot.

February 2, 2015. The Cytognomix MutationForecaster system

Feb 3, 2015   //   by Peter Rogan   //   News  //  Comments Off

MutationForecaster is our new, comprehensive genome interpretation suite to interpret and validate mutations that affect mRNA splicing and protein coding. Our products can find and validate mutations that others cannot.

Here`s proof:

(Click any of the images below to view the paper)

MutationForecaster brings together our world class software in a single easy-to-use interface:

  • The popular Automated Splice Site and Exon Definition server (ASSEDA)
  • The Shannon pipeline for genome scale mRNA splicing mutation analysis
  • Veridical, the first solution for validating splicing mutations by RNASeq
  • Variant Effect Predictor for identification of coding changes and predicting their impact
  • Cytognomix User Variation Database, to store and compare results obtained with these tools with other sources of genomic variation
  • Our Visual analytics Decision Support Tool, for cytogenomic interpretation, and single copy hybridization genomic reagent design

December 30, 2014. Veridical software status update

Dec 30, 2014   //   by Peter Rogan   //   News  //  Comments Off

Veridical is now hosted by Cytognomix. The previous website has been migrated to

This software product has been integrated into our new MutationForecaster webservice.  To validate splicing mutations predicted by the Shannon pipeline,  a set of gene variants (in vcf format) and RNASeq data (in bam format) are uploaded for the same individual.   Control data are built in, the analysis is automated, and results are returned directly to users. Subscriptions to MutationForecaster will be available from Cytognomix in early 2015.

The standalone software is also available from Cytognomix, which licenses it and provides installation support. To further inquire, contact us at
