Kidney Renal Clear Cell Carcinoma: Correlation between gene mutation status and selected clinical features

Maintained by TCGA GDAC Team (Broad Institute/Dana-Farber Cancer Institute/Harvard Medical School)

Overview

Introduction

This pipeline computes the correlation between significantly recurrent gene mutations and selected clinical features.

Summary

Testing the association between mutation status of 98 genes and 9 clinical features across 293 patients, 3 significant findings detected with Q value < 0.25.

BAP1 mutation correlated to 'TUMOR.STAGE'.
NUDT11 mutation correlated to 'AGE'.
FBXO43 mutation correlated to 'Time to Death'.

Methods & Data

Input

Mutation data file = KIRC.mutsig.cluster.txt
Clinical data file = KIRC.clin.merged.picked.txt
Number of patients = 293
Number of significantly mutated genes = 98
Number of selected clinical features = 9
Exclude genes that fewer than K tumors have mutations, K = 3

Survival analysis

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

Student's t-test analysis

For continuous numerical clinical features, two-tailed Student's t test with unequal variance (Lehmann and Romano 2005) was applied to compare the clinical values between tumors with and without gene mutations using 't.test' function in R

Fisher's exact test

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

Q value calculation

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.
