GeneDx now offers a cost-effective and sensitive alternative for the diagnosis of the 65 common or novel microdeletion and microduplication syndromes and for examining subtelomeric and pericentromeric genomic regions. This new test, called FISHonChipDx, also includes confirmation of positive findings by FISH. This test has greater technical sensitivity and is more economical than equivalent subtelomere panel and/or single-locus FISH testing. The FISHonChipDx array can also provide size information for detected deletions and duplications. GeneDx also offers individual FISH tests for a range of genomic disorders and for subtelomeric and pericentromeric rearrangements.
