Additional studies showed gene expression profile differences between plexiform and follicular ameloblastomas, with follicular ameloblastomas expressing variants of BRAF, KMT2D, and ABL1, while plexiform ameloblastomas expressed variants of ALK, BRAF, KRAS, KMT2D, SMO, KMT2A, and BRCA2 [33, 34]. The gene discussed is ABL1; the disease is ameloblastoma.
