Overview
Introduction

This pipeline computes the correlation between significant arm-level copy number variations (cnvs) and subtypes.

Summary

Testing the association between copy number variation 32 arm-level results and 10 molecular subtypes across 197 patients, 23 significant findings detected with Q value < 0.25.

  • 7p gain cnv correlated to 'CN_CNMF',  'MIRSEQ_CHIERARCHICAL', and 'MIRSEQ_MATURE_CNMF'.

  • 7q gain cnv correlated to 'CN_CNMF' and 'MIRSEQ_MATURE_CNMF'.

  • 8p gain cnv correlated to 'CN_CNMF' and 'RPPA_CHIERARCHICAL'.

  • 8q gain cnv correlated to 'CN_CNMF',  'RPPA_CNMF',  'RPPA_CHIERARCHICAL',  'MIRSEQ_CNMF',  'MIRSEQ_CHIERARCHICAL', and 'MIRSEQ_MATURE_CNMF'.

  • 6q loss cnv correlated to 'CN_CNMF'.

  • 8p loss cnv correlated to 'METHLYATION_CNMF',  'MRNASEQ_CNMF',  'MRNASEQ_CHIERARCHICAL', and 'MIRSEQ_CNMF'.

  • 13q loss cnv correlated to 'CN_CNMF'.

  • 16q loss cnv correlated to 'CN_CNMF' and 'MIRSEQ_CHIERARCHICAL'.

  • 17p loss cnv correlated to 'CN_CNMF'.

  • 18q loss cnv correlated to 'CN_CNMF'.

Methods & Data
Input

  • Mutation data file = broad_values_by_arm.mutsig.cluster.txt

  • Molecular subtypes file = PRAD-TP.transferedmergedcluster.txt

  • Number of patients = 197

  • Number of significantly arm-level cnvs = 32

  • Number of molecular subtypes = 10

  • Exclude genes that fewer than K tumors have mutations, K = 3

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.
