# cBioPortal: public-cohort mutations

TCGA PanCancer breast cancer cohort, hg19. Up to 5 genes and 25 rows per page. Page counts are not cohort prevalence. No therapeutic interpretation is included.

## Scope

Computational research analysis. It does not establish diagnosis, pathogenicity, efficacy or treatment. Check population, provenance, version and scope before interpreting.

Interface and contracts implemented on ELUCENIA. Analysis depends on the responsible service being available. Independent clinical review and professional language review are incomplete.

## Query

- Gene symbols
- Page
- I confirm that I will submit only public or synthetic research data, without patient or confidential data.

## Waiting limits

Each request to this provider has a 20-second limit. The complete workflow has a 120-second limit; the interface waits at most 125 seconds. Requests share the workflow’s remaining time. There is no automatic retry. If the provider does not respond in time, analysis ends with an explicit error; no result is estimated or substituted.
