Note: Scoring of VCF files with CADD v1.7 is still rather slow if many new variants need to be calculated from scratch (e.g., if many insertion/deletion or multinucleotide subsitutions are included). If possible use the pre-scored whole genome and pre-calculated indel files directly where possible. We are very sorry for the inconvenience.

Single nucleotide variant (SNV) lookup

This form allows you to quickly access the score (and annotation) of a single nucleotide variant (SNV) or all scores at a specific genomic position. If you are investigating multiple or even ranges of CADD SNV scores, please have a look at our Multi-SNV scoring form. Please note that copying and downloading of the annotation tables is not working in Internet Explorer.

CADD scores are freely available for all non-commercial applications. If you are planning on using them in a commercial application, please contact us.
