Rearrangements of MAF/IGH are recurring abnormalities in plasma cell dyscrasia disorders including Plasma Cell Myeloma. According to current mSMART 3.0 myeloma guidelines, rearrangement of MAF/IGH is classified as a high-risk cytogenetics category. 

This test can be ordered individually or as part of a Plasma Cell Dyscrasia FISH Panel. See the individual panel test for more details.
