MitImpact

MitImpact annotates and models the effects of nucleotide changes that cause non-synonymous substitutions in human mitochondrial protein-coding genes to assess impacts on oxidative phosphorylation (OXPHOS) complexes, bioenergetics, adaptation, and disease.

Key Features:

• Comprehensive annotations: Provides genomic, clinical, and functional annotations for all non-synonymous substitutions in the human mitochondrial genome.
• Compensated Pathogenic Deviations (CPDs): Reports putative CPDs that may be pathogenic but are compensated by other variants.
• Co-varying amino acid sites: Identifies co-varying amino acid sites in Respiratory Chain subunits.
• Molecular dynamics simulations: Applies molecular dynamics simulation techniques to evaluate energetic and structural residue compensation in mitochondrial proteins.
• Pathogenicity predictions: Includes pre-computed pathogenicity predictions for non-synonymous substitutions.
• OXPHOS focus: Centers analyses on oxidative phosphorylation (OXPHOS) complexes and mitochondrial protein stability and function.

Scientific Applications:

• Disease mechanism investigation: Facilitates investigation of mitochondrial contributions to disease mechanisms using annotated variant effects and pathogenicity predictions.
• Evolutionary adaptation studies: Enables exploration of adaptive changes and compensatory evolution in mitochondrial proteins.
• Mitochondrial–nuclear interaction analysis: Supports analysis of mitochondrial–nuclear interactions through annotated variant datasets.
• Bioenergetics assessment: Allows assessment of impacts on OXPHOS function and cellular bioenergetics.

Methodology:

Uses molecular dynamics simulation techniques to assess energetic and structural residue compensation, alongside pre-computed pathogenicity predictions.
