In cases where comprehensive NGS analysis cannot be performed or the diagnosis is highly suspect, we offer a variety of single-gene fluorescence in situ hybridization (FISH) tests to identify common genetic rearrangements in the genes EWSR1, USP6, TFE3, PDGFB, SS18, SYT, FUS, DDIT3, CHOP, FOXO1, FKHR, NR4A3, ETV6, ALK, and others.
In some cases, the genetic abnormality may be something other than a fusion, and testing is available to support these cases. One such abnormality is the ring and giant rod chromosomes derived from amplified sequences of chromosome bands 12q13-15, which include several amplified genes such as MDM2, CPM, CDK4, and TSPAN31.

William Sukov, M.D., provides an overview of the MDM2 gene amplification assay — a test that looks for amplification of the MDM2 gene region on chromosome 12q. He reviews when this test should be ordered, how it compares to other test options, and how its results can affect patient care.
