Techniques used to diagnose this disorder are fluorescence in situ hybridization (FISH) and microarrays. FISH uses fluorescent dyes to visualize sections under a microscope, but some changes are too small to see. Microarray comparative genomic hybridization (array CGH) shows changes in small amounts DNA on chromosomes.
