Here, we present TIVAN (TIssue-specific Variant Annotation and prediction) to predict cis-eQTL SNVs by considering tissue-specificity. TIVAN is trained based on a comprehensive collection of features including genome-wide genomic and epigenomic profiling data. TIVAN has been shown to accurately discriminate cis-eQTL SNVs from non-eQTL SNVs and perform favorably to other methods. This site provides the pre-computed scores for hg19 and software toolkit to obtain the scores for queried variants.

To successfully run the example below, we strongly recommend at least 4GB memory for the PC/laptop/Work station. The example has been successfully performed on a MacBook laptop with a 1.7 GHz processor and 8 GB memory.

Installation, GenomicRanges R Bioconductor package


An example to obtain score for a list of eQTL SNVs from Adipose_Subcutaneous

Adipose_Subcutaneous.eQTL.rda could be downloaded from Here

Adipose_Subcutaneous.score.rda could be downloaded Here

hg19.SNVs.rda could be downloaded Here

getscore.R could be downloaded Here

# hg19.SNVs.rda contains an object hg19.SNVs, which SNVs for hg19
# Adipose_Subcutaneous.score.rda contains an object score, which is pre-computed scores for hg19 SNVs in Adipose_Subcutaneous
# Adipose_Subcutaneous.eQTL.rda contains an object snp1, which are eQTL SNVs for Adipose_Subcutaneous
