Gene Normalizer

image image image Actions status DOI

Overview

The Gene Normalizer provides tools for resolving ambiguous human gene references to consistently-structured, normalized terms. For gene concepts extracted from NCBI Gene, Ensembl, and HGNC, it designates a CURIE, and provides additional metadata like current and previously-used symbols, aliases, database cross-references and associations, and coordinates.

Install

The Gene Normalizer is available on PyPI:

python3 -m pip install gene-normalizer

See installation instruction in the documentation for a description of installation options and data setup requirements.

Examples

Use the live service to programmatically normalize gene terms, as in the following truncated example:

$ curl 'https://normalize.cancervariants.org/gene/normalize?q=BRAF' | python -m json.tool
{
    "query": "BRAF",
    "match_type": 100,
    "normalized_id": "hgnc:1097",
    "gene": {
        "type": "Gene",
        "id": "normalize.gene.hgnc:1097"
        "label": "BRAF",
        "gene_id": "hgnc:1097",
        "aliases": [
            "BRAF1",
            "B-RAF1",
            "NS7",
            "RAFB1",
            "B-raf",
            "BRAF-1"
        ]
    }
    # ...
}

Or utilize the Python API for fast access:

>>> from gene.database import create_db
>>> from gene.query import QueryHandler
>>> q = QueryHandler(create_db())
>>> result = q.normalize("KRAS")
>>> result.normalized_id
'hgnc:6407'

See the usage and normalization entries in the documentation for more.
