Genetic testing methods such as fluorescence in situ hybridization (FISH) and chromosomal microarray are available for diagnosing<unk>  syndrome and similar genetic disorders. With the increase in genetic testing availability, more often duplications outside of the 15q11.2-13.1 region are being diagnosed. The global chromosome 15q11.2-13.1 duplication syndrome specific groups only provide medical information and research for chromosome 15q11.2-13.1 duplication syndrome and not the outlying 15q duplications.
