Recently, pediatric malignant peritoneal mesothelioma cases have been genetically studied, with alterations observed in ALK, EWSR1, FUS1, YY1, or in AURKA, AURKC, HLA-1B, ZNF-217, OR5F1, and MEN1 genes, but not in BAP1 [28,29]. This evidence concerns the gene OR5F1 and malignant peritoneal mesothelioma.
