As aplicações clínicas desta técnica estendem-se desde a pesquisa da etiologia do atraso de desenvolvimento e do autismo, até ao estudo pré-natal em gestações de alto risco. They are also very valuable in screening the genome for DNA gains and losses at an unprecedented resolution. This is because balanced chromosomal abnormalities such as reciprocal translocations , inversions or ring chromosomes do not affect copy number, which is what is detected by CGH technologies. European Journal of Pediatrics — In begründeten Fällen ist eine Elternuntersuchung mittels dieser Methode angezeigt, um eine Einschätzung der klinischen Relevanz beim Kind identifizierter Veränderungen zu erlauben. Views Read Edit View history. It has the potential to detect CNVs and aneuploidy in eggs, sperm or embryos which may contribute to failure of the embryo to successfully implant, miscarriage or conditions such as Down syndrome trisomy

In both techniques, DNA from a reference or control sample and DNA from a test or patient sample are differentially labelled with two different fluorophores and used as probes that are cohybridized competitively onto nucleic acid targets. CGC Genetics can offer two different resolutions, where the highest resolution has the greatest diagnostic capability:. From Wikipedia, the free encyclopedia.

Array CGH has been in use in clinical practice since Sie verwenden einen veralteten Browser, welcher von dieser Website nicht unterstützt wird. The technique involves whole genome amplification from a single cell which is then used in the array CGH method.

This makes array CGH a promising tool to reduce the incidence of life altering conditions and improve success rates of IVF attempts. CGH is only able to detect unbalanced chromosomal abnormalities. A higher intensity of the test sample colour in a specific region of a chromosome indicates the gain of material of that region in the corresponding source sample, while a higher intensity of the reference sample colour indicates the loss of material in the test sample in that specific region.

May be completed using DNA isolation kits available commercially which are based on affinity columns. They are also very valuable in screening the genome for DNA gains and losses at an unprecedented resolution. It may be designed to study a specific chromosome or chromosomal segment or to identify and evaluate specific DNA dosage abnormalities in individuals with suspected microdeletion syndromes or subtelomeric rearrangements. For example, Levy et al. Array CGH applications are mainly directed at detecting genomic abnormalities in cancer. Download as PDF Printable version. Though not yet a widely employed technique, the use of array CGH as a tool for preimplantation genetic screening is becoming an increasingly popular concept. Array CGH has been implemented using a wide variety of techniques. CGH can also only detect gains and losses relative to the ploidy level.

After hybridization, digital imaging systems are used to capture and quantify the relative fluorescence intensities of each of the hybridized fluorophores. Conventional CGH has been used mainly for the identification of chromosomal regions that are recurrently lost or gained in tumors, as well as for the diagnosis and prognosis of cancer. This alliance of different resources allows us to meet the higher European quality standards in the field of Medical Genetics.

Array CGH has been implemented using a wide variety of techniques. Although oligonucleotides do not have the sensitivity to detect single copy changes, averaging of ratios from oligos that map next to each other on the chromosome can compensate for the reduced sensitivity. Array CGH may also be applied not only to the discovery of chromosomal abnormalities in cancer, but also to the monitoring of the progression of tumors.
