Hi,  
I was looking at a specific mutation in PA1 PPM1D (see below) and found that the Sanger WES ref:alt information was missing from the PA1 Mutation page on DepMap but in the CCLE\_mutations.csv file there is a value of 39:7.

Is there a reason why these numbers aren’t displayed or is this a bug?

Hi Shawn,

Thank you for flagging this. We’ve added this to our development queue and will investigate further.
