Data dbSNP is not a database of polymorphisms Conservation scores depend on sequences and alignment algorithms Transcripts can be misplaced (very unusual) Protein domains are mostly predicted Orthologues are mostly computed 01/03/2013UK NEQAS UV Participants Meeting

Missense Predictions Why Align GVGD, PolyPhen-2, SIFT, MutationTaster? – Reputation – Automatability – Right to use in commercial software Complex algorithms based on AA physico-chemical properties, AA conservation, protein structure, and more Predictions ±strongly depend on Alamut-supplied orthologue alignment 01/03/2013UK NEQAS UV Participants Meeting

Splicing Predictions Why SSF, MaxEnt, NNSPLICE, GeneSplicer, HSF? – ditto Simple algorithms based on sequence MaxEnt often considered as the most accurate (Splicing regulation predictions: for experts only!) 01/03/2013UK NEQAS UV Participants Meeting

Quality Contribution Up-to-date data Visual feedback HGVS nomenclature (when in doubt check with Mutalyzer) Manually-curated orthologue alignments NGS alignment and coverage visualization 01/03/2013UK NEQAS UV Participants Meeting
