Other subgroups of myoepithelial tumors of soft tissue are associated with alternative genetic aberrations such as rearrangements of other genes (e.g., PLAG1 [41]) or homozygous deletion of the INI1/SMARCB1 gene [42–44], while in a large proportion, the genetic background is not yet known. This evidence concerns the gene PLAG1 and myoepithelial tumor.
