But beware……!!!!! There are many examples of known pathogenic variants predicted to be benign and vice versa

Batch Annotators & Prioritization Gene Panel / Whole Exome Sequencing • Large amounts of variants (50-50,000) • Needed information for interpretation: • Location w.r.t. gene (intron/exon/splicing) • Effect on CDS (synonymous/stop-gain/frameshift/...) • Severity of the effect • Function of gene w.r.t. phenotype Example Applications: wANNOVAR: http://wannovar.usc.edu SeattleSeq: http://snp.gs.washington.edu/SeattleSeqAnnotation141/ VEP: http://www.ensembl.org/Tools/VEP VariantDB: http://biomina.be/apps/variantdb eXtasy: http://extasy.esat.kuleuven.be/ Exomiser: http://www.sanger.ac.uk/science/tools/exomiser
