The most commonly mutated genes include SWI/SNF (SWItch/Sucrose Non-Fermentable), MEN-1 (Multiple Endocrine Neoplasia type 1), PSIP1 (PC4 And SRSF1 Interacting Protein 1), and ARID1A (AT-Rich Interaction Domain 1A) [18]. This evidence concerns the gene ARID1A and multiple endocrine neoplasia type 1.
