Comparative genomic hybridization using oligonucleotide microarrays and total genomic DNA.
Array-based comparative genomic hybridization (CGH) measures copy-number variations at multiple loci simultaneously, providing an important tool for studying cancer and developmental disorders and for developing diagnostic and therapeutic targets. Arrays for CGH based on PCR products representing assemblies of BAC or cDNA clones typically require maintenance, propagation, replication, and verif...
متن کاملChromosomal 16p microdeletion in Rubinstein-Taybi syndrome detected by oligonucleotide-based array comparative genomic hybridization: a case report
INTRODUCTION Chromosomal aberrations of chromosome 16 are uncommon and submicroscopic deletions have rarely been reported. At present, a cytogenetic or molecular abnormality can only be detected in 55% of Rubinstein-Taybi syndrome patients, leaving the diagnosis in 45% of patients to rest on clinical features only. Interestingly, this microdeletion of 16 p13.3 was found in a young child with an...
متن کاملPrenatal diagnosis of genomic disorders and chromosome abnormalities using array-based comparative genomic hybridization.
Cytogenetic analysis is a crucial tool of prenatal diagnosis. The ability to rapidly detect aneuploidy and identify small structural abnormalities of foetal chromosomes has been greatly improved by the use of molecular cytogenetic technologies. Microarray-based Comparative Genomic Hybridization (aCGH) has been recently employed in postnatal diagnosis of cryptic chromosomal aberrations, but use ...
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...
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...
