Overview
Introduction

This pipeline computes the correlation between significant copy number variation (cnv focal) genes and selected clinical features.

Summary

Testing the association between copy number variation 62 focal events and 11 clinical features across 311 patients, 7 significant findings detected with Q value < 0.25.

  • amp_2q33.1 cnv correlated to 'GENDER'.

  • amp_8q13.3 cnv correlated to 'GENDER'.

  • amp_8q24.21 cnv correlated to 'GENDER' and 'RACE'.

  • del_4q21.3 cnv correlated to 'AGE'.

  • del_4q35.1 cnv correlated to 'RACE'.

  • del_16q23.1 cnv correlated to 'RACE'.

Methods & Data
Input
  • Copy number data file = transformed.cor.cli.txt

  • Clinical data file = LIHC-TP.merged_data.txt

  • Number of patients = 311

  • Number of significantly focal cnvs = 62

  • Number of selected clinical features = 11

  • 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

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.
