FishingCNV: a graphical software package for detecting rare copy number variations in exome-sequencing data

Summary:
Rare copy number variations (CNVs) are frequent causes of genetic diseases. We developed a graphical software package based on a novel approach that can consistently identify CNVs of all types (homozygous deletions, heterozygous deletions, heterozygous duplications) from exome-sequencing data without the need of a paired control. The algorithm compares coverage depth in a test sample against a background distribution of control samples and uses principal component analysis to remove batch effects. It is user friendly and can be run on a personal computer.
Availability And Implementation:
The main scripts are implemented in R (2.15), and the GUI is created using Java 1.6. It can be run on all major operating systems. A non-GUI version for pipeline implementation is also available. The program is freely available online: https://sourceforge.net/projects/fishingcnv/
Supplementary Information:
Supplementary data are available at Bioinformatics online.

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%...
