The number of genes and transcripts we have in Ensembl can make your VEP results very big. Filtering your results after running the VEP is the best way to make this more manageable, but you can also reduce the results in your run itself, to only get one result per variant or variant/gene combo.

As the community’s capacity for genome sequencing expands, so do its ambitions. Recently, many exciting global genomics projects have been launched, including the Vertebrate Genomes Project (VGP), Darwin Tree of Life (DToL), Earth Biogenome Project EBP, i5K (insects) and 10KP (plants). Between them, they aim to sequence the genomes of every eukaryote on Earth, and Ensembl are excited to take on the annotation of some of those genomes.
We’re looking for a software development manager to lead our infrastructure team, maintaining our database, API infrastructure and internal genome analysis tools. We’re looking for MScs, PhDs or equivalent in Computational, Physical or Biological Sciences with experience developing APIs, communicating technical information, software development and working with large datasets. Closes 10th April.
The VEP can work as an offline or a web tool and it’s also available as REST service. Perfect for integrating into pipelines or displaying data on the web, the REST API VEP endpoints can take input as HGVS, genomic loci or variant identifiers and can interpret common forms of non-standard HGVS. They are all available using both GET and POST protocols, supporting queries on single or multiple variants respectively.
We’re looking for a software developer to join our Applications team, working on web applications and our REST APIs. We’re looking for MScs in Computer Science with experience working in development using Git, Python, RDBMSs, Agile development and REST APIs. Closes 2nd April.
Identifying the causal variants from a GWAS generally involves identifying the haplotype blocks that contain your variant of interest, rather than the variant and the gene it is affecting itself. To find the actual genes involved, you need to consider all variants in LD with your identified associations. Ensembl Post-GWAS analysis pipeline (PostGAP) can provide automatic fine-tuning of your GWAS variants, incorporating regulatory information and population-wide LD calculations, along with your VEP results.
Most of the time when we talk about variant annotation, we talk about the effects of variants on genes, but did you know that the VEP can also tell you how variants affect the genomic features that regulate gene expression, such as promoter and enhancers?
If a variant hits a splice site, you want to know if splicing is going to occur as normal, or if you can expect a different protein isoform. We have a few cool tools with the VEP that will help you to assess that for your own variants.
