Variant Function Prediction

Question

[User 1933]

Basically, I would like to know what are some variant function/effect predictor ? I already know SIFT and Polyphen and mutationassessor. I was curious if there is any other that I have missed.

GMCC reports supporting annotations for the specified genomic region. The particular strength of the GMCC is it works in genomic space, not simply in spliced transcript space as some similar tools do. Within gene features, GMCC can report on the effects on splice site, UTR and coding regions in all isoforms affected by the mutation. Website http://cbio.mskcc.org/gmcc

TransFIC improves the assessment of the functional impact of tumor nsSNVs by taking into account the basal tolerance of genes to high impacting functional variants in the human population.

Answer 2

[Emily]

You're looking for a variant effect predictor? I would suggest the Variant Effect Predictor.

[User 1933]

that is same as SIFT and Polyphen 2

[Emily]

Yes, those are available options.

Answer 3

[Jorge Amigo]

as a good starting point, you may find ANNOVAR's list of functional annotations very interesting: SIFT, PolyPhen, PhyloP, LRT, MutationTaster, MutationAssessor, FATHMM, SiPhy, GERP++, MetaSVM and MetaLR, and the recently published CADD C score.

Answer 4

[Pablo]

You can use most of the annotations proposed at the same time with SnpEff/SnpSift + dbNSFP

http://snpeff.sourceforge.net/SnpSift.html#dbNSFP

You have the following scores form dbNSFP:

Answer 5

[Naga]

You can also use MutationTaster and Provean

[User 1933]

seems they don't work with hg19 - but thank you in any case

[Naga]

GRCh37 and h19 are same. So, PROVEAN should work.

Answer 6

[christopher medway]

I am going to throw HaploReg into the ring. It is a great tool to explore the potential effects of non-coding variants.

[le.marcorin]

I am using Haploreg to study some non-coding regions but I 'm having problems understanding those values in the 'Regulatory motifs altered' area in the end of the page. Could you help me? I already read the paper from Kheradpour and Kellis, 2013, but it didn't help

[Noushin N]

you can also use bioinformatics tools CHASM and VEST via CRAVAT webserver: http://www.cravat.us
