This track shows AlphaMissense predictions for all possible single amino acid substitutions in the human proteome.
AlphaMissense is a deep learning method for predicting the pathogenicity of missense variants in human proteins. It classifies 32% of all missense variants as likely pathogenic and 57% as likely benign using a cutoff yielding 90% precision on the ClinVar dataset.
There are four lettered subtracks, one for every nucleotide, showing scores for mutation from the reference to that nucleotide. All subtracks show the AlphaMissense score on mouseover. Across the exome, there are three values per position, one for every possible nucleotide mutation. The fourth value, "no mutation", representing the reference allele, e.g. A to A, is always set to zero, "0.0". AlphaMissense only takes into account amino acid changes, so a nucleotide change that results in no amino acid change (synonymous) is not scored. These are shown in the tracks with score "0.0".
When using this track, zoom in until you can see every basepair at the top of the display. Otherwise, there are several nucleotides per pixel under your mouse cursor and no score will be shown on the mouseover tooltip.
Track colors
This track is colored according to the am_class column in the AlphaMissense_$db.tsv file.
| Range | Classification |
|---|---|
| ≥ .564 | Likely Pathogenic |
| .565 - .340 | Likely Neutral |
| ≤ .340 | Likely Benign |
AlphaMissense scores are available at the - + AlphaMissense cloud storage site. The site provides precomputed AlphaMissense scores for all possible human missense variants to facilitate the identification of pathogenic variants among the large number of rare variants discovered in sequencing studies. -
