High resolution comparative genomic hybridisation in clinical cytogenetics.
High resolution comparative genomic hybridisation (HR-CGH) is a diagnostic tool in our clinical cytogenetics laboratory. The present survey reports the results of 253 clinical cases in which 47 abnormalities were detected. Among 144 dysmorphic and mentally retarded subjects with a normal conventional karyotype, 15 (10%) had small deletions or duplications, of which 11 were interstitial. In addi...
متن کاملHigh resolution microarray comparative genomic hybridisation analysis using spotted oligonucleotides.
BACKGROUND Currently, comparative genomic hybridisation array (array CGH) is the method of choice for studying genome wide DNA copy number changes. To date, either amplified representations of bacterial artificial chromosomes (BACs)/phage artificial chromosomes (PACs) or cDNAs have been spotted as probes. The production of BAC/PAC and cDNA arrays is time consuming and expensive. AIM To evalua...
متن کاملMosaic supernumerary ring chromosome 19 identified by comparative genomic hybridisation.
We report the use of comparative genomic hybridisation (CGH) to define the origin of a supernumerary ring chromosome which conventional cytogenetic banding and fluorescence in situ hybridisation (FISH) methods had failed to identify. Targeted FISH using whole chromosome 19 library arm and site specific probes then confirmed the CGH results. This study shows the feasibility of using CGH for the ...
متن کاملThe genetic screening of preimplantation embryos by comparative genomic hybridisation.
Comparative genomic hybridization (CGH) is an indirect DNA-based test which allows for the accurate analysis of aneuploidy involving any of the 24 types of chromosomes present (22 autosomes and the X and Y sex chromosomes). Traditionally, embryos have been screened using fluorescence in situ hybridization (FISH)--a technique that was limited in the number of chromosomes able to be identified in...
متن کاملComparative genomic hybridisation as a supportive tool in diagnostic pathology.
AIMS Patients with multiple tumour localisations pose a particular problem to the pathologist when the traditional combination of clinical data, morphology, and immunohistochemistry does not provide conclusive evidence to differentiate between metastasis or second primary, or does not identify the primary location in cases of metastases and two primary tumours. Because this is crucial to decide...
