PGD for a complex chromosomal rearrangement by array comparative genomic hybridization.
Patients carrying a chromosomal rearrangement (CR) have an increased risk for chromosomally unbalanced conceptions. Preimplantation genetic diagnosis (PGD) may avoid the transfer of embryos carrying unbalanced rearrangements, therefore increasing the chance of pregnancy. Only 7-12 loci can be screened by fluorescence in situ hybridization whereas microarray technology can detect genome-wide imb...
متن کاملPGD for reciprocal and Robertsonian translocations using array comparative genomic hybridization.
BACKGROUND Fluorescence in situ hybridization (FISH) is the most widely used method for detecting unbalanced chromosome rearrangements in preimplantation embryos but it is known to have several technical limitations. We describe the clinical application of a molecular-based assay, array comparative genomic hybridization (array-CGH), to simultaneously screen for unbalanced translocation derivati...
متن کاملNovel chromosomal imbalances in mantle cell lymphoma detected by genome-wide array-based comparative genomic hybridization.
Mantle cell lymphoma (MCL) is an aggressive, highly proliferative B-cell non-Hodgkin lymphoma, characterized by the specific t(11;14)(q13;q32) translocation. It is well established that this translocation alone is not sufficient to promote MCL development, but that additional genetic changes are essential for malignant transformation. We have identified such additional tumorigenic triggers in M...
متن کاملArray comparative genomic hybridization in male infertility.
BACKGROUND Male infertility caused by a maturation arrest of spermatogenesis is a condition with an abrupt stop in spermatogenesis, mostly at the level of primary spermatocytes. The etiology remains largely unknown. METHODS We focused on patients with a complete arrest at the spermatocyte level (n = 9) and used array comparative genomic hybridization to screen for deletions or duplications th...
متن کاملArray-based comparative genomic hybridization for the genomewide detection of submicroscopic chromosomal abnormalities.
Microdeletions and microduplications, not visible by routine chromosome analysis, are a major cause of human malformation and mental retardation. Novel high-resolution, whole-genome technologies can improve the diagnostic detection rate of these small chromosomal abnormalities. Array-based comparative genomic hybridization allows such a high-resolution screening by hybridizing differentially la...
