cbioportal-database

You can query cancer genomics data from cBioPortal without an API key by using the REST API to fetch mutations, copy-number alterations, and clinical attributes by specifying Entrez gene IDs, study profiles, and sample lists.

Pan-cancer analysis compares alteration frequencies and survival associations across hundreds of cancer studies like TCGA and GENIE, allowing researchers to explore oncogene and tumor-suppressor patterns at a broad scale.

Yes, you can retrieve mRNA expression and clinical survival data from TCGA studies by querying the cBioPortal REST API for molecular profiles and clinical attributes without requiring an API key.

No, you do not need an API key to access cBioPortal molecular profiles and clinical data; the REST API allows direct querying of mutations, CNAs, and expression data using study identifiers and Entrez gene IDs.

The best way to analyze somatic mutations and copy-number alterations for target validation is querying cBioPortal's REST API across studies like MSK-IMPACT to fetch mutation lists and compare gene alterations.

To fetch mutations for a specific gene, query the cBioPortal REST API using the Entrez gene ID alongside the desired study and molecular profile identifiers to return a detailed mutation list.
