SNPs and GO

SNPs and GO predicts whether nonsynonymous (missense) single nucleotide variants in human protein sequences are disease-related or neutral by integrating protein sequence, evolutionary information, and Gene Ontology (GO) functional annotations.

Key Features:

• Disease vs neutral prediction: Determines if a given nonsynonymous (missense) mutation is likely disease-related or neutral.
• Integrated evidence types: Combines protein sequence data, evolutionary conservation information, and Gene Ontology (GO) functional annotations for prediction.
• Mutation scope: Targets nonsynonymous (missense) single nucleotide polymorphisms (SNPs) in human proteins.
• Performance and benchmark: Reported scoring efficiency of 82% and Matthews correlation coefficient (MCC) of 0.63 on a dataset of 16,330 annotated disease-related polymorphisms and 17,432 neutral polymorphisms.

Scientific Applications:

• Variant interpretation: Assessment of the potential clinical relevance of missense SNPs in human proteins.
• Disease association studies: Prioritization of candidate mutations for studies of genetic susceptibility to human diseases.
• Functional impact analysis: Investigation of how amino acid substitutions may affect protein function using sequence, evolutionary, and GO information.

Methodology:

Integrates protein sequence data, evolutionary conservation information, and Gene Ontology (GO) functional annotations to predict whether nonsynonymous (missense) mutations are disease-related or neutral; evaluated on a curated dataset of 16,330 disease-related and 17,432 neutral polymorphisms yielding 82% scoring efficiency and MCC 0.63.
