Single Nucleotide Substitutions (SNP) represent the majority of human genetics variations with about 80,000 variants per human exome and more than 3,000,000 ​ variations per human genome. SNPs also account for most human disease-causing mutations with approximately 56% of missense and nonsense mutations. If classifying nonsense mutations as disease-causing is trivial, the classification of missense or synonymous mutations is challenging.

The UMD-Predictor system is an innovative bioinformatics solution to predict the pathogenicity of any SNP from any human transcript. It relies on an original combinatorial approach that consistently outperformed other predictors as illustrated in the figure adapted from Salgado et al. 2016.

The UMD-Predictor algorithm combines the following features:

  • Blosum62 conservation matrix (global conservation)

  • Yu’s biochemical substitution matrix (based on 48 physicochemical properties of amino acids)

  • Protein key residues (both for structure or activity)

  • Predicted impact on splicing signals (splice sites and auxiliary sequences)

  •  Variation frequency at the human population level

  • Conservation score in 100 species with Grantham’s substitution matrix (protein specific conservation)

Each parameter has a different weight corresponding to its biological consequence. Thus the alteration of a wild type donor or acceptor splice site has a major weight, while the creation of a cryptic splice site is limited.


The accuracy of UMD-Predictor has been assessed with four reference datasets (early 2016 datasets): Varibench [Sasidharan Nair and Vihinen, 2013] with dbSNP [Sherry et al., 2001] (19,335 pathogenic, 7,897 nonpathogenic); Uniprot [UniProt Consortium, 2014] (20,821 pathogenic, 36,825 non- pathogenic); Clinvar [Landrum et al., 2014] (10,669 pathogenic, 1,817 nonpathogenic), and PredictSNP [Bendl et al., 2014] (24,082 pathogenic, 19,800 nonpathogenic). 

The UMD-Predictor database contains all potential SNP from human transcripts. It is thus the fastest system (x16 on average) and produces the shortest list of candidate pathogenic variations (36% of other systems on average) leading to a strong benefit for downstream validation.

The UMD-Predictor system is accessible for regular users through a software as a service  license. It can be integrated in any bioinformatics pipeline through web services. Bioinformatics companies willing to include UMD-Predictor into their systems have various options to do it and should contact us.
