PON-Del predictor for short protein deletions


PON-Del is a predictor for short (1-10 amino acid) sequence retaining deletions. It was trained on an extensive set of variations and showed superior performance compared to other tools. After evaluating multiple frameworks, LightGBM was selected as the final model.

PON-Del Overview

Input deletions

Deletion type
Note: Highly recommend to use protein-level variant. If submit with transcript or genomic, we will use transvar to convert to protein level and it may miss some cases. Maximum 1000 lines allowed. Deletions starting at position 1 will return Pathogenic because deletion of the first amino acid (usually methionine) may prevent normal protein expression.

Note: Deletions starting at position 1 return Pathogenic because deletion of the first amino acid (usually methionine) may prevent normal protein expression and are beyond the scope of the current prediction model.

Single amino acid deletions

            

            

              
This page provides precalculated results for all possible single amino acid deletions in proteins coded by MANE transcripts.

              
Deletions starting at position 1 return Pathogenic because deletion of the first amino acid (usually methionine) may prevent normal protein expression.

 Note:
 PON-Del is developed based on MANE selectedRefSeq protein identifiers. 

 If you select a different identifier type, the corresponding RefSeq protein will be displayed. 

 The one-to-one mapping is defined by the MANE v1.4.
