The cBioPortal for Cancer Genomics provides visualization, analysis and download of large-scale cancer genomics data sets.

Please adhere to the TCGA publication guidelines when using any TCGA data in your publications.

The portal is developed and maintained by the Computational Biology Center at Memorial Sloan-Kettering Cancer Center.

  • Patient-specific view for TCGA endometrial cancer case TCGA-BK-A0CC.

    The most prominent or most interesting genomic alteration events from an individual tumor sample can now be browsed and analyzed in the portal.

  • Network of genomic alterations in Serous Ovarian Cancer.

    Network of BRCA1, BRCA2 and all altered neighbors, as identified in the TCGA ovarian cancer data set. Pink shading indicates frequency of alteration across all patients (white = low frequency of alteration; red = high frequency of alteration); Green discs indicate rate of mutation across all patients.

  • Structural view of a PIK3R1 mutation in Glioblastoma

    The D560Y variant of PIK3R1 in glioblastoma is shown on the PIK3R1 protein structure (on the Mutation Assessor website). The mutated residue is shown in red.

  • TP53 mutations in ovarian cancer

    TP53 is mutated in 95% of serous ovarian cancer patients. Some of these mutations are truncating, and most of the missense mutations are predicted to have a high functional impact (prediction by Mutation Assessor).

What People are Saying

  "Whenever bench scientists ask me how they can look at TCGA data, I've never had a good answer for them. Now I do. The cBio Portal meets a critical need--it is the interface that the cancer research community needs to access the wealth of TCGA. Even as a computational biologist, I use it to follow-up on genes of interest. It makes querying the data much less painful."

– Postdoctoral Fellow, Oregon Health & Science University

  "I would like to congratulate you and the team of the cBio portal. It's just an amazing tool to work with, and we at Mass General really appreciate it."

– Research Fellow at Massachusetts General Hospital

  "As a bench biologist with primary aim of determining gene aberrations in GBM, I found your site absolutely fantastic! Thank you! I have to reiterate how awesome and user-friendly your group has made this site - finally accomplishing the goal of having data easily accessible and meaningful."

– Sr. Research Associate at Knight Cancer Institute/OHSU

  "Thank you for your incredible resource that has helped greatly in accessing the TCGA genomics data."

– Postdoctoral Fellow, Harvard Medical School, Children's Hospital Boston

  "This portal is truly the greatest thing since sliced bread. I am making discoveries with it not only in glioblastoma, my primary focus, but in other cancers as well -- it?s all so easy with this fantastic tool. And I am enjoying showing it to my colleagues, whose jaws also drop. Thank you a thousand times over for this beautiful public resource. I am looking forward to citing this soon in an upcoming paper..."
