Question: Vep Not Giving Annotation With Refseq Transcript

I'm trying to annotate variants with the ensembl Variant Effect Predictor and I'd prefer to get my variant annotation done with refseq transcripts but VEP does not seem to be doing this even when I explicitly mention this in the options.

For example the variant

1    100672060    rs12021720    T    C

Clearly lies in the third exon of this refseq transcript:

2    NM_001918    chr1    -    100652477    100715409    100661810    100715376    11    100652477,100671785,100672000,100676249,100680372,100681538,100684181,100696288,100700991,100706316,100715325,    100661978,100671857,100672192,100676327,100680539,100681755,100684303,100696470,100701067,100706440,100715409,    0    DBT    cmpl    cmpl    0,0,0,0,1,0,1,2,1,0,0,

Yet VEP seems intent on giving me annotation only in terms of CCDS & Ensembl transcripts.

Any ideas on why this happens? I tried both the command line and online versions and I get the same result.

Can you paste the command here?

ADD REPLYlink written 6.1 years ago by Ashutosh Pandey12k

I added the command but it will likely not be of help because VEP annotations depend on which version of the annotation database you download. I used the refseq based database during installation. The results are reproducible from the online vep tool.

I thought you may be missing the "--refseq" flag. BTW, I found this post that can be relevant to your problem (

Thanks for the link, I read through that in my google searches and that's how I ended up including the --refseq flag. That still doesn't rectify my issue since I'm using the proper database. I decided to post here since I've seen someone from Ensembl respond to these questions on this forum but I'll likely have to e-mail the list serve to get a solution. VEP is a pretty comprehensive tool that gives me a lot of my annotation information except for this issue.

If nobody replies you can try contacting Emily (Emily_Ensembl) about the same. She should be able to figure out what is going wrong.

Clearly I have a reputation here. I'm going to pass this onto Will, who made and maintains the VEP, to see what he says.

It looks like the Ensembl otherfeatures database (from which the RefSeq cache is built) is missing this transcript.

I'm not sure why this would be, but I can pass this on to our genebuilders who may be able to help.

Yes I'm using the right file, like I mentioned in the post you can reproduce the same result on the online VEP tool by selecting the refseq option.
