SNPeffect

SNPeffect predicts structural and functional consequences of non-synonymous single nucleotide variants (SNVs) in protein-coding genes to assess effects on protein aggregation, amyloidogenicity, chaperone binding, catalytic sites, post-translational modifications, and stability.

Key Features:

• Sequence- and Structure-Based Predictions: Integrates sequence data with structural information to evaluate how non-synonymous SNVs affect protein structural phenotype.
• Aggregation Prediction (TANGO): Uses TANGO to assess aggregation propensity of sequence regions affected by SNVs.
• Amyloid Prediction (WALTZ): Uses WALTZ to identify potential amyloidogenic regions altered by SNVs.
• Chaperone-Binding Prediction (LIMBO): Uses LIMBO to predict changes in molecular chaperone-binding propensity caused by SNVs.
• Protein Stability Analysis (FoldX): Uses FoldX to evaluate the impact of SNVs on protein thermodynamic stability.
• Functional Annotations: Reports affected catalytic sites and post-translational modification annotations in the context of SNVs.
• Extensive Variant Database: Includes all known human protein variants from UniProt and supports analysis of submitted custom protein variants with automated structure modeling.
• Meta-Analysis Application: Provides plotting of correlations between phenotypic features across selected variants for comparative analyses.

Scientific Applications:

• Structural Variant Interpretation: Interprets how non-synonymous SNVs alter protein structure and stability to inform variant pathogenicity assessments.
• Protein Misfolding and Aggregation Research: Identifies aggregation-prone and amyloidogenic sequence changes relevant to misfolding diseases.
• Pharmacogenomics and Drug Response: Assesses structural effects of SNVs that may influence drug-binding sites or protein stability related to drug response variability.
• Personalized Variant Analysis: Enables analysis of individual or novel protein variants through automated structure modeling and phenotype prediction.

Methodology:

Applies sequence- and structure-based prediction using TANGO, WALTZ, LIMBO, and FoldX, incorporates UniProt variants and automated structure modeling for custom variants, and generates correlation plots of phenotypic features.
