Hello Experts and Champions,

How to annotate SV and CNV vcf files generated from tools like WHAM, Delly, LUMPY, CNVNATOR, GenomeStrip etc ? I know their are plenty of tools for SNV but I am just wondering what are ways to annotate SV's ?

Thanks in advance

Hi,

I'm annotating my CNV / SV human events with the AnnotSV tool:

http://www.lbgi.fr/AnnotSV/

PMID: 29669011 DOI: 10.1093/bioinformatics/bty304

It associates a complete panel of different datasets to provide high quality structural variations (SV) / CNV annotation :

  • Gene annotations

  • Promoters annotations

  • DGV Gold Standard annotations

  • DECIPHER gene annotations

  • 1000 genomes annotations

  • GC content annotations

  • Repeated sequences annotations

  • TAD annotations

  • OMIM annotations

  • Gene intolerance annotations

  • Haploinsufficiency annotations

  • Homozygous and heterozygous SNV/indel annotations

  • ...

AnnotSV starts by detecting the genomic overlaps between the input and the annotation features.

Moreover, interesting information, this tool constructs an annotation based on the full-length SV but also an annotation for each gene within the SV.

Really easy to install and to use!

Input format: VCF or BED

Else, if you have CNV calls from four different CNV callers, I advise you (before to annotate) to identify/merge the common CNV detected by your different callers. For that, I would consider CNV that share a 70% reciprocal overlap measured by length and position (> 70% shared length) (as done in DGV).

Please, would you let us know, does AnnotSV also infer fusions and truncations depending on gene orientation and SV orientation ? Thank you !

Could you please explain more? Can you give an input/output example of what you wish?

Try the Variant Effect Predictor, or VEP. It does annotate both Structural variants and SNVs. It's available as an online tool, Perl script or through the Ensembl Rest API.

Not really. VEP doesn't support the very common BND SVType.

Data generated from CREST,and i want to annotation it like snp ,because I saw someone else do that,Can you give me an example?

You'll need to put more effort in your question and elaborate on the data you have, what you tried and what didn't work, with commands and error messages.

Welcome to biostars. Interesting guidelines for posting can be found in the following posts:
