Visualization of genes and genetic variants as well as transcript structure is essential within the human genetics community. Such illustrations represent a key tool in communicating genetic concepts and facilitating discussions on therapeutic interventions. There currently are no easily usable tools which allows the users to draw all features required for a comprehensive overview of a transcripts structure and the localisation of variants of interest. Here we introduce ExonViz, an online application that creates biologically accurate transcript figures, including features such as coding regions, genetic variants and exon reading frames. Transcript definitions are automatically retrieved from Ensembl and RefSeq. We illustrate the full functionality of ExonViz by generating a figure for all variants reported in ClinVar for CYLD. ExonViz is available online via the Dutch Center for RNA Therapeutics website and can be installed locally via PyPI.

Matching journals

The top 2 journals account for 50% of the predicted probability mass.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
