What problem does it solve?
This Skill addresses the challenge of annotating genetic variants and gene information efficiently using Ensembl's comprehensive API. It simplifies tasks such as querying variant effects, regulatory features, coordinate conversions, and gene cross-references from Ensembl's extensive genomic databases.
Core Features & Use Cases
- Variant Effect Prediction (VEP): Annotate variants with their predicted impact, regulatory overlap, and pathogenicity scores using Ensembl's VEP service. For example, assess the consequence of a SNP on gene function or regulatory regions.
- Regulatory Feature Overlap: Identify regulatory elements like enhancers, promoters, or CTCF sites within specific genomic regions, aiding in the interpretation of non-coding variants.
- Coordinate Liftover: Convert genomic coordinates between GRCh37 and GRCh38, ensuring compatibility with diverse datasets and annotations.
- Gene Lookup & Cross-References: Retrieve detailed gene metadata and cross-reference identifiers between Ensembl IDs and external databases, supporting downstream functional analyses.
- Phenotype Associations: Access disease and phenotype links to genomic regions or genes, supporting genotype-phenotype correlation efforts.
A typical application would involve annotating GWAS variants with predicted effects, regulatory context, and gene relationships to interpret their biological significance efficiently.
Quick Start
Query the Ensembl REST API to get annotations for a specific variant or gene and interpret the data to understand the variant’s potential functional impact.
