The investigators have developed a proprietary design of oligonucleotide probes for comparitive genomic hybridization to detect copy number variation in the diagnosis of genetic etiologies of developmental delay and autism spectrum disorders. Using this technology, the investigators have identified a deletion/duplication event at chromosome 16p11.2 as the most prevalent genetic abnormality underlying autism spectrum discorder, and a second deletion/duplication event at chromosome 15p13.3 underlying a syndrome of autism and other neuropsychiatirc disorders.
Diagnostic screening of developmental delay of unknown etiology.
The proprietary oligonucleotide-based microarray design has been developed for the multiplex diagnosis of copy number variation in the etiology of developmental delay or autism spectrum disorder.
