Improved display of Germline mutations

May 14, 2018 | By Sander Tan




The Hyve recently developed visualization for germline mutations in cBioPortal OncoPrint.

AstraZeneca-Logo-1 This feature was sponsored by AstraZeneca and has been shared with the community on and on cBioPortal GitHub.


Use case

Inherited germline mutations can increase the probability of developing a tumor. This is for example well known for the BRCA genes in breast and ovarian cancer1, 2. Knowledge of these germline mutations can result in effective preventive measures.

Previously, germline mutations in cBioPortal could only be differentiated from somatic mutations in the mutation or patient view, by a red annotation in the protein change column in the Mutation view.

New functionality

In cBioPortal 1.13.0 and later, germline mutations will have a white horizontal bar across their oncoprint rectangle. This will allow the user to easily differentiate them from somatic mutations.

When hovering over a patient with a germline mutation, the germline status will be displayed in the pop-up box.
