VariED

VariED integrates gene annotation, expression profiles, variant allele frequencies, functional prediction scores, and clinical interpretations across human, mouse, and zebrafish to support DNA variant analysis in genetic disease research.

Key Features:

• Integrated database: Consolidates gene annotation, variant allele frequency, functional predictions, clinical interpretations, and gene expression profiles for human, mouse, and zebrafish.
• Variant–expression integration: Associates DNA variant annotations with gene expression profiles across human, mouse, and zebrafish to support cross-species analysis of regulatory effects.
• Functional impact scoring: Implements a novel scoring scheme that aggregates functional prediction scores to predict the functional impact of DNA variants.
• Clinical and population annotation: Aggregates clinical interpretations and allele frequency information to inform pathogenicity assessment.
• Genome information organization: Organizes genome information to support identification and analysis of gene regulatory networks implicated in disease mechanisms.
• Result aggregation: Compiles and outputs consolidated results for queried DNA variants in a single aggregated response.

Scientific Applications:

• Gene regulatory network analysis: Enables analysis of gene regulatory networks underlying disease mechanisms by linking variants and expression data across species.
• Drug discovery: Supports identification of potential drug targets and pathway analysis through integrated variant and expression data.
• Precision medicine: Informs personalized treatment approaches by combining variant annotations, functional predictions, allele frequencies, and clinical interpretations.
• Functional genomics: Facilitates studies of variant effects on gene function and phenotype manifestation using cross-species expression and annotation data.

Methodology:

Computationally consolidates gene annotation, variant allele frequency, functional prediction scores, clinical interpretations, and gene expression profiles across human, mouse, and zebrafish and applies a novel scoring scheme to predict functional impact of DNA variants; it also connects to established online querying tools, biological annotation resources, and free-text literature records.
