Breast Invasive Carcinoma: Association of mutation, copy number alteration, and subtype markers with pathways
(primary solid tumor cohort)
Maintained by Spring Yingchun Liu (Broad Institute)
Overview
Introduction

This pipeline maps genes, with mutation or copy number alteration AND this alteration is highly correlated with mRNA expression, to pathways curated in the KEGG and BIOCARTA databases. It identifies pathways significantly enriched with these genes. The pipeline also identifies pathways significantly enriched with marker genes of each expression subtype of cancer.

genes with mutation: identified by the Mutation_Significance pipeline

genes with copy number alteration: identified by the CopyNumber_Gistic2 pipeline

correlation between copy number and mRNA expression: identified by the Correlate_CopyNumber_vs_mRNA pipeline

marker genes and expression subtypes: identified by the mRNAConsensusClustering pipeline

Summary

There are 26 genes with significant mutation (Q value <= 0.1) and 171 genes with significant copy number alteration (Q value <= 0.25). The identified marker genes (Q value <= 0.01 or within top 2000) are 2000 for subtype 1, 2000 for subtype 2, 2000 for subtype 3. Pathways significantly enriched with these genes (Q value <= 0.01) are identified :

0 pathways significantly enriched with genes with copy number alteration or mutation.

0 pathways significantly enriched with marker genes of gene expression subtype 1

0 pathways significantly enriched with marker genes of gene expression subtype 2

1 pathways significantly enriched with marker genes of gene expression subtype 3

Methods & Data
Enrichment

Let genes with copy number alteration or mutation be query genes. Let marker genes of specific identified subtypes be query genes. The Enrichment is calculated as:

  • Enrichment = log2 (# of query genes in the pathway/# No of query genes) - log2 (# of genes in the pathway/# of human genes)

P value

The statistical signficance of the pathways that are enriched with genes with copy number alteration or mutation, and the pathways that are enriched with markers genes of specific identified subtypes is measured by P value.

  • P value = Fisher exact P value

Q value

The Q value is for adjusting P value for multiple testing. A public available R package is used to calculate the Q value.
