What is aCGH used for?

Array Comparative Genomic Hybridisation (aCGH) is a microarray-based technique to detect alterations in Genomic DNA sequence. Array CGH is widely used for clinical research into constitutional cytogenetics, rare disease, cancer and reproductive health.

What is CGH microarray testing?

What is array CGH? Array CGH is a significant advance in technology that allows detection of chromosome imbalances that are too small to be detected by looking down the microscope. Karyotyping is only as good as the resolution of the microscope and is not able to detect subtle chromosome changes.

What is array comparative genomic hybridization aCGH analysis?

Array comparative genomic hybridization (aCGH): Identifies losses or gains of DNA across the whole genome. Whole tumor DNA is labeled with fluorophores and hybridized to a DNA probe set covering most of the genome, which is mounted on a solid surface such as a glass slide.

What is the difference between fish and array comparative genomic hybridization?

Both FISH and aCGH rely upon nucleic acid hybridization, with the use of designed probes to detect specific DNA targets. However, aCGH can probe thousands of genetic loci simultaneously, providing wider coverage of the genome and higher throughput in the initial stages of testing than FISH.

What does CGH microarray test for?

The main advantage of array CGH is the ability to explore all 46 chromosomes in a single test and to detect any DNA imbalance including extra or missing chromosomes and loss or gain of chromosome material much more precisely than conventional chromosome analyses.

What are the disadvantages of CGH?

Disadvantages of a CGH array Balanced chromosomal rearrangements, such as translocations or inversions. Chromosomal localisation of duplications (requires an additional FISH test). Low frequency mosaicism (<30% of abnormal cells). Some types of polyploidy such as triploidy. Uniparental disomy (UPD).

What is array comparative genome hybridization?

Array comparative genomic hybridization (also microarray-based comparative genomic hybridization, matrix CGH, array CGH, aCGH) is a molecular cytogenetic technique for the detection of chromosomal copy number changes on a genome wide and high-resolution scale.

What is the difference between CGH and array CGH?

Array CGH is automated, allows greater resolution (down to 100 kb) than traditional CGH as the probes are far smaller than metaphase preparations, requires smaller amounts of DNA, can be targeted to specific chromosomal regions if required and is ordered and therefore faster to analyse, making it far more adaptable to
