Abstract:
Pathway-based analysis approaches provide additional insights into the pathogenesis of complex diseases. Copy number variations (CNVs) play an important role in gene expression regulation. Joint pathway analysis of CNVs and gene expression data should provide more useful information for revealing the molecular mechanism of complex diseases. To implement trans-omics pathway analysis of genome-wide CNVs and mRNA expression profiles data, we extended the gene set enrichment analysis algorithm and developed a flexible trans-omics pathway analysis tool CPAS. CPAS was developed by C to interface with R for efficient data analysis. CNV-gene and pathway-gene annotation files derived from public database were included in CPAS. We hope that CPAS could help to identify disease-relevant biological pathways that were undetectable using traditional single-omic analysis approaches.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
