Evaluation of calling algorithms for array-CGH
Copy number variation (CNV) detection has become an integral part many of genetic studies and new technologies promise to revolutionize our ability to detect and link them to disease. However, recent studies highlight discrepancies in the genome wide CNV profile when measured by different technologies and even by the same technology. Furthermore, the change point algorithms used to call CNVs ca...
متن کاملCGHcall: calling aberrations for array CGH tumor profiles
UNLABELLED CGHcall achieves high calling accuracy for array CGH data by effective use of breakpoint information from segmentation and by inclusion of several biological concepts that are ignored by existing algorithms. The algorithm is validated for simulated and verified real array CGH data. By incorporating more than three classes, CGHcall improves detection of single copy gains and amplifica...
متن کاملI-45: FISH and Array CGH for PGD of Cancer
We developed several FISH approaches to enable preimplantation genetic diagnosis of cancer predisposition syndromes. An overview of the applications and the results of those PGDs will be provided. In addition we developed several novel tools to genome wide screen for CNVs and SNPs in single cells. Those technologies are now being applied for polar body, blastomere and blastocyst screening for c...
متن کاملA method for calling gains and losses in array CGH data.
Array CGH is a powerful technique for genomic studies of cancer. It enables one to carry out genome-wide screening for regions of genetic alterations, such as chromosome gains and losses, or localized amplifications and deletions. In this paper, we propose a new algorithm 'Cluster along chromosomes' (CLAC) for the analysis of array CGH data. CLAC builds hierarchical clustering-style trees along...
متن کاملCGH-Explorer: a program for analysis of array-CGH data
SUMMARY CGH-Explorer is a program for visualization and statistical analysis of microarray-based comparative genomic hybridization (array-CGH) data. The program has preprocessing facilities, tools for graphical exploration of individual arrays or groups of arrays, and tools for statistical identification of regions of amplification and deletion.
