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 69 arm-level results and 7 clinical features across 562 patients, 10 significant findings detected with Q value < 0.25.

  • Amp Peak 2(1q21.3) cnv correlated to 'AGE'.

  • Amp Peak 12(8p11.21) cnv correlated to 'AGE'.

  • Amp Peak 14(10p15.3) cnv correlated to 'AGE'.

  • Amp Peak 17(12p13.33) cnv correlated to 'AGE'.

  • Amp Peak 18(12p12.1) cnv correlated to 'AGE'.

  • Amp Peak 25(19q12) cnv correlated to 'AGE'.

  • Amp Peak 26(19q13.2) cnv correlated to 'AGE'.

  • Amp Peak 28(20q11.21) cnv correlated to 'AGE'.

  • Amp Peak 29(20q13.33) cnv correlated to 'AGE'.

  • Del Peak 28(16q23.1) cnv correlated to 'AGE'.

Methods & Data
Input

  • Mutation data file = all_lesions.conf_99.cnv.cluster.txt

  • Clinical data file = OV-TP.clin.merged.picked.txt

  • Number of patients = 562

  • Number of significantly arm-level cnvs = 69

  • Number of selected clinical features = 7

  • 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.
