To whom it may concern,

I would like to enquire about definition of putative driver/passenger mutations on cBioPortal.

After I submitted queries on cBioPortal, I found that in the OncoPrint session, some mutations are classified as putative driver whereas some others are putative passenger. Please, may I know how do you define or classify a certain mutation as driver/passenger? Is is based on published studies or based on prediction of the mutations' effect on protein structural changes or any other criteria?

I would be grateful if you would kindly answer my questions! Thank you so much for your time!

Hi Wenying,

Driver and passenger information is based on prior knowledge (from oncokb.org) or statistical recurrence (cancerhotspots.org).

We do not take the predicted effect into account.

Hi Wenying,

we are working on a solution to allow custom annotations to be used in the oncoprint. See https://docs.google.com/document/d/1pZq2_geY5yuCRd43tsrKOjQ8EJ9u4RIh3KmJXADy9Mc/edit and 
https://github.com/cBioPortal/cbioportal/pull/2896

Best regards,

Pieter

Dear Dr. Schultz,

Thank you so much for your kind reply! I'm very very sorry for the late reply due to some personal reasons.

I checked the mutations on both websites that you sent me, OncoKB and Cancer Hotspots. Whereas I could find most of the putative driver mutations on these websites, I couldn't find many of the mutations that were defined as putative passenger. From another email reply from Mr. Pieter Lukasse, the "custom annotation of driver and passenger mutations" is explained in a github link. After reading the documentation, I found that apart from database such as OncoKB and Cacner Hotspots, the frequency of a certain mutation in the patient population is also taken into consideration for defining driver or passenger. So I am wondering, for those putative passenger mutations that I could not find reference in OncoKB or Cancer Hotspots, are they defined so due to low occurrence in a certain patient cohort?

Best Regards!
Wenying
