Thyroid Adenocarcinoma: Correlation between gene mutation status and selected clinical features
(primary solid tumor cohort)

Maintained by TCGA GDAC Team (Broad Institute/MD Anderson Cancer Center/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 27 genes and 14 clinical features across 241 patients, 8 significant findings detected with Q value < 0.25.

BRAF mutation correlated to 'HISTOLOGICAL.TYPE', 'EXTRATHYROIDAL.EXTENSION', and 'LYMPH.NODE.METASTASIS'.
HRAS mutation correlated to 'HISTOLOGICAL.TYPE'.
NRAS mutation correlated to 'HISTOLOGICAL.TYPE'.
CCDC15 mutation correlated to 'LYMPH.NODE.METASTASIS'.
ATAD2 mutation correlated to 'NUMBER.OF.LYMPH.NODES' and 'TUMOR.SIZE'.

Methods & Data

Input

Mutation data file = THCA-TP.mutsig.cluster.txt
Clinical data file = THCA-TP.clin.merged.picked.txt
Number of patients = 241
Number of significantly mutated genes = 27
Number of selected clinical features = 14
Exclude genes that fewer than K tumors have mutations, K = 3

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

Chi-square test

For multi-class clinical features (nominal or ordinal), Chi-square tests (Greenwood and Nikulin 1996) were used to estimate the P values using the 'chisq.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.
