Does My Gene of Interest Affect Survival?
You can use Xena Kaplan Meier plot (KM plot) to test whether a genomic or phenotype variable significantly affects survival.
IDH1 is an enzyme that affects metabolism in tumors and is frequently mutated in Lower Grade Glioma.
Running a KM analysis, we can see there is a significant overall survival difference between patients with IDH1 mutation and those without.
To Reproduce the IDH example
Go to our Visualization tab
Select the TCGA Lower Grade Glioma cohort
Enter the gene 'IDH1', click 'Mutation' and 'Gene expression' and click 'Done'.
Note that there is a '!' warning at the top of the plot indicating that some samples are in the plot twice (normal, recurrent tumor, metastasis, etc). To remove duplicate samples, please see our help page.
