PLAG1 and malignant myoepithelioma: SGPA was never reported in association with CdC, so the genes located in 5p- deletion are unlikely to have relevance in the development of the tumor; among them, TERT (5p15.33) is related to tumor development, but it is not expressed in a series of SGPA and normal parotid tissue [21], and its involvement in salivary gland was only reported in a case of a myoepithelial carcinoma gland in a 76-year-old lady [22].
