Genomic data visualization is an extremely powerful means to help users comprehend massive amounts of sequencing data and is valuable for communicating genomic information and findings. Genome browser tools allow users to visualize aligned sequence data in BAM format, map the data to a reference assembly, view annotation tracks, genomic region tracks, export graphics for sharing, and much more. Genome… Read more »
The customer-published articles this October cite the range of Golden Helix’s VarSeq annotation range and capability. The following publications feature everything from annotating an Italian nobleman mummy, assisting in identifying mutations in primary congenital and juvenile glaucoma, new mutations associated with muscular dystrophinopathy, and germline variants associated with head and neck cancer. In each of these cases, VarSeq was utilized… Read more »
The Genome Aggregation Database (gnomAD) is a resource developed by an international coalition of investigators, with the goal of aggregating and harmonizing both exome and genome sequencing data from a wide variety of large-scale sequencing projects (1). We have covered this annotation in-depth in other blog posts, but this resource contains over 125,000 exome sequences and around 16,000 whole genome… Read more »
One of the inherent realities of next-generation sequencing is the ongoing updates to the human reference genome—one of the strongest recommendations to take the original sequencing data and remap to the latest genome assembly. However, there are several reasons why remapping may be impractical. So, an alternative solution is needed to convert the data running through an initial mapping to… Read more »
Smoothing Hurdles into Speed Bumps when creating Annotation Sources Although most researchers assume that getting the pile of VCF sequence files is the largest hurdle in moving towards an analysis, there still exists the looming step of normalizing the variant calls in annotation sources to make variant comparison easier. In this ever-refining field of study, VarSeq continually works to increase… Read more »
The VarSeq clinical platform is built on a strong foundation of data curation and annotation algorithms to ensure the variants identified have all the information required to make the correct clinical assessments. It’s easy to make light of “variant annotation”, but the details run very deep into the roots of how we represent genomic data, how public data is aggregated, stored… Read more »
As VarSeq continues its adoption amongst clinical labs and researchers looking for reproducible workflows for variant annotation, filtering and interpretation, we have continued to prioritize the addition of features to assess the quality of the upstream data at a variant, coverage and now sample level. The Importance of Quality Assurance Sample prep and sequencing problems are difficult to detect through the analysis… Read more »
