I-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 کاملPGD in female carriers of balanced Robertsonian and reciprocal translocations by first polar body analysis.
Preimplantation genetic diagnosis (PGD) using the first polar body (1PB) is a modality of PGD that can be used when the woman is the carrier of a genetic disease or of a balanced chromosomal reorganization. PGD using 1PB biopsy in carriers of balanced chromosome reorganizations has not become generalized. Here, we describe our experience based on the analysis of unfertilized or fresh, non-insem...
متن کاملPolar body array CGH for prediction of the status of the corresponding oocyte. Part I: clinical results
BACKGROUND Several randomized controlled trials have not shown a benefit from preimplantation genetic screening (PGS) biopsy of cleavage-stage embryos and assessment of up to 10 chromosomes for aneuploidy. Therefore, a proof-of-principle study was planned to determine the reliability of alternative form of PGS, i.e. PGS by polar body (PB) biopsy, with whole genome amplification and microarray-b...
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.
متن کاملThe array CGH and its clinical applications.
Array comparative genomic hybridization (aCGH) is a technique enabling high-resolution, genome-wide screening of segmental genomic copy number variations (CNVs). It is becoming an essential and a routine clinical diagnostic tool and is gradually replacing cytogenetic methods. Most of the clinically available aCGH platforms are designed to detect aneuploidies, well-characterized microdeletion/mi...
