Clinical utility of array comparative genomic hybridization: uncovering tumor susceptibility in individuals with developmental delay

J Pediatr. 2009 Jan;154(1):143-6. doi: 10.1016/j.jpeds.2008.07.045.


Microarray-based comparative genomic hybridization can determine genome-wide copy number alterations at the kilobase level. We highlight the clinical utility of microarray-based comparative genomic hybridization in determining tumor susceptibility in 3 patients with dysmorphic features and developmental delay, likely decreasing both morbidity and mortality in these patients.
