ID:927 Array CGH
Search Links: General Info : Protocols : Patient Info

DescriptionArray CGH is a technique for detecting abnormalities of genomic copy number.
IndicationPatients presenting with unexplained learning difficulties / developmental delay / behavioural problems (including autism and referrals for the fragile X phenotype). Patients with dysmorphism / multiple congenital abnormalities suggestive of a chromosome abnormality.
Additional InfoIt is a high resolution whole genome screen which detects genetic imbalances at a greater resolution (60Kb) compared with karyotyping (5-10Mb), ie a ~1000 fold increase in resolution. This increase in resolution detects a higher number of genomic gains and losses (imbalances) directly related to the patientís phenotype than can be seen using karyotype + MLPA. Array CGH also accurately identifies the type and location of the pathogenic genes involved in chromosome imbalances.
