Reporting on Cancer Biomarkers may seem like a daunting task, both in determining the scope of what a biomarker can encompass and which information to include. Biomarkers can come in the form of small variants (SNPs and INDELs), copy number variants, and structural variants. Biomarkers can also be sourced from external cancer kits in the form of a Genomic Signature,… Read more »

Compound heterozygosity describes the relationship between two alternate alleles when they are located within the same gene but at different loci within that gene. Compound heterozygosity is particularly relevant in a recessive disorder when the presence of these alleles in combination confers an increased risk of disease, similar to a traditional homozygous recessive combination of alleles. The detection of compound… Read more »

DNA methylation is becoming more relevant as a clinically important biomarker, and long-read pipelines are making it easy to get this information in the same sequencing run as small variants and larger structural variants. Even though there are no official guidelines for addressing DNA methylation, it is still useful to analyze and evaluate this data, so we would like to… Read more »
In a recent blog post, we explored how phased genotypes provide crucial insights by separating variants into distinct haplotypes—groups of alleles inherited together from a single parent. We also discussed how the combined impact of multiple variants within the same gene can significantly differ from their individual effects. However, accurately assessing the joint impact of these in-phase variants is a… Read more »
You might have noticed an uptick in the number of interpretations associated with hematological cancers within the Golden Helix CancerKB database over the past several months. This is because the CancerKB curation team has been focused on bolstering our drug sensitivity, diagnostic, and prognostic interpretations. This project has had the team reading through the NCCN Guidelines, WHO Guidelines and International… Read more »
In the upcoming release of VarSeq 2.6.2, we have added the ability to force call reference alleles using the BAM files associated with the sample. This feature extends the current force call functionality, which allows filling in reference alleles from GVCFs. This is an important option to enable when running pharmacogenomics pipelines with VarSeq, as it allows for inferring the… Read more »
The following customer publications showcase the ability of VarSeq. Each study demonstrates the abilities of VarSeq’s annotation and filtering of variants and the ease of identifying with our software. Rare host variants in ciliary expressed genes contribute to COVID-19 severity in Bulgarian patients Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19), a pneumonia with extremely heterogeneous clinical… Read more »
Our webcast on Integrating Long and Short Read Sequencing for Comprehensive NGS Analysis was a timely review of a topic. We discussed how users are leveraging both short and long-read sequencing modalities for comprehensive NGS analyses, reviewing the differences between long and short-read sequencing, the benefits and limitations of each modality, and how they complement each other. The theme was how… Read more »
Phased genotypes provide crucial information that allows us to separate variants into distinct haplotypes, representing the sequence of alleles inherited together from a single parent. This information can offer profound insights into inheritance patterns, the combined functional effects of variants, and the identification of specific genetic profiles such as pharmacogenomic diplotypes. In this blog post we describe how phased genotypes… Read more »
Periodically, our FAS team will see a situation where a customer has installed VarSeq on a new machine…but something is not entirely right. Perhaps a VCF will not load, annotations cannot download, or a long-running process like coverage regions will not complete. Any of these issues alone can be tricky to troubleshoot, whether due to a permissions block, a lack… Read more »
Cloud computation is a hot topic across industries that require scalable software solutions to enable growth, and for good reason. The cloud, in all its mystical appeal, has so mellifluously penetrated the zeitgeist that experts engaging with new software solutions are often eager to hear how they fit into the cloud computing ecosystem. In the world of next-generation sequencing (NGS),… Read more »
