Ensembl Variant Lookup provides a web-based graphical interface, allowing users to retrieve information about genetic variants based on their Reference SNP ID (RSID). This application integrates with the Ensembl Variant API to provide detailed variant information.
Ensembl Variant Lookup is a Python tool built with Flask that allows users to query and retrieve information about genetic variants from the Ensembl database. It provides a user-friendly interface for searching individual variants, batch queries, and exploring gene regions. The tool is designed to streamline the retrieval of essential genetic variant data, making it a valuable resource for genomics research and exploration.
- Single Variant Lookup: Retrieve detailed information about a specific genetic variant using its RSID.
- Batch Variant Lookup: Perform batch searches by entering a list of RSIDs and obtaining information for multiple variants simultaneously.
- Gene Lookup: Fetch information about a specific gene, including details on associated variants.
Simplified illustration at high-level of API exposed in thie application, it includes all the API endpoints in the diagram:

This flowchart now includes the following API endpoints:
/batch(POST): Batch search for variants by rsid list./variant(POST): Search for variants by rsid./gene_region(GET): Search for variants in a gene region./visualize(POST): Visualize variants for a specific gene.
Use pip to install the Ensembl Variant Lookup package.
pip install ensembl-variant-lookup-
Run the Application:
