About MutPred


MutPred is a web application tool developed to classify an amino acid substitution (AAS) as disease-associated or neutral in human. In addition, it predicts molecular cause of disease/deleterious AAS. MutPred is based upon SIFT [1] and a gain/loss of 14 different structural and functional properties. For instance, gain of helical propensity or loss of a phosphorylation site. It was trained using the deleterious mutations from the Human Gene Mutation Database [2] and neutral polymorphisms from Swiss-Prot [3]. Current version of MutPred is 1.2. The update consists of replacing SIFT score by a more stable version of code that calculates evolutionary conservation. In addition, the I-mutant software was replaced by a more stable MUpro [4], by the Baldi group. The training data set was updated to contain 39,218 disease-associated mutations from HGMD and 26,439 putatively neutral substitutions from Swiss-Prot.

How do I interpret the results?
The output of MutPred contains a general score (g), i.e., the probability that the amino acid substitution is deleterious/disease-associated, and top 5 property scores (p), where p is the P-value that certain structural and functional properties are impacted.

Certain combinations of high values of general scores and low values of property scores are referred to as hypotheses.

  1. Scores with g > 0.5 and p < 0.05 are referred to as actionable hypotheses.
  2. Scores with g > 0.75 and p < 0.05 are referred to as confident hypotheses.
  3. Scores with g > 0.75 and p < 0.01 are referred to as very confident hypotheses.

MutPred is a collaborative effort between the Mooney group from the University of Washington and the Radivojac group from the School of Informatics and Computing, Indiana University.

We welcome any suggestions and comments.
