Postnatal array comparative genomic hybridization (array CGH) is indicated for use for individuals with dysmorphic features, congenital anomalies, developmental delay, mental retardation and/or autism spectrum disorders. It is also indicated as a reflex test following normal chromosome results if a genomic imbalance is suspected.
Array CGH provides information on genomic imbalances, including some that may be too small to detect by conventional cytogenetic methods.
For a list of conditions – including those associated with Autism Spectrum Disorders – that are part of the Genzyme Genetics microarray, please see the Array CGH disorders list.
