This pipeline computes the correlation between significantly recurrent gene mutations and selected clinical features.
Testing the association between mutation status of 36 genes and 8 clinical features across 280 patients, 5 significant findings detected with Q value < 0.25.
-
TP53 mutation correlated to 'Time to Death'.
-
IDH1 mutation correlated to 'Time to Death' and 'YEARS_TO_BIRTH'.
-
ATRX mutation correlated to 'YEARS_TO_BIRTH'.
-
LZTR1 mutation correlated to 'ETHNICITY'.

Exclude genes that fewer than K tumors have mutations, K = 3
For survival clinical features, the Kaplan-Meier survival curves of tumors with and without gene mutations were plotted and the statistical significance P values were estimated by logrank test (Bland and Altman 2004) using the 'survdiff' function in R
For binary or multi-class clinical features (nominal or ordinal), two-tailed Fisher's exact tests (Fisher 1922) were used to estimate the P values using the 'fisher.test' function in R
For multiple hypothesis correction, Q value is the False Discovery Rate (FDR) analogue of the P value (Benjamini and Hochberg 1995), defined as the minimum FDR at which the test may be called significant. We used the 'Benjamini and Hochberg' method of 'p.adjust' function in R to convert P values into Q values.
