CLUMP (CLustering by Mutation Position)

is a method that performs unsupervised clustering of amino acid residue positions where variants occur, without any prior knowledge of their functional importance.

Visualizing the distribution of missense variants in a given protein sequence can be informative in relation to identifying potentially causal variants. However, such visualization does not provide quantitative assessment of clustering patterns and it cannot be applied in a high-throughput setting. CLUMP is a method for the rapid determination of mutation clustering patterns and their statistical significance.
