Array comparative genomic hybridization (also microarray-based comparative genomic hybridization, matrix CGH, array CGH, aCGH) is a molecular cytogenetic technique for the detection of …

What is array CGH? A technique used in molecular biology for the detection of genomic dosage changes (deletions or duplications) at a much higher level of resolution than karyotyping.

Researchers are now using array CGH (aCGH), to quickly scan through an entire genome for imbalances. Many human genetic disorders result from unbalanced chromosomal abnormalities, in …

Array CGH is a genetic test that looks for extra or missing genetic material from your DNA. Differences in the amount of genetic material can sometimes cause health problems.

There are two different ways of performing microarray testing: single nucleotide polymorphism array (SNP array) and array comparative genomic hybridisation (aCGH).

Array CGH will detect some but not all cases of mosaicism (the chromosome anomaly is not present in all the cells of the body; a proportion of the body’s cells have a different chromosome make-up).

The technique used in place of karyotyping is called array comparative genomic hybridization (array-CGH) which accurately identifies both the location and gene content of pathogenic chromosome …

Jun 16, 2025 · An array CGH, or comparative genomic hybridization array, is a genetic test that examines a person’s DNA for specific types of changes. It is designed to detect gains or losses in …

Array based comparative genomic hybridization (array CGH) has emerged as a powerful tool for detecting gene copy number variants implicated in many disease states.

Array comparative genomic hybridization with single nucleotide polymorphism (aCGH+SNP) analysis is used to examine the entire genome for pathogenic copy number variant (pCNVs, deletions and …
