However, several groups of gene mutations have been found in this case (the mutation abundance was over 3%), such as LRP1B, TAS2R8, PRRC2A, OR51G1, PCDHAC2, C4orf17, UGT1A, OR5D16, TOPAZ1, SYT4, APCDD1L, ITPR1, PPP1R3C, KIF21B, PVRL3, PANK4, C5orf42, and C19orf54, which may be of certain value to the diagnosis and treatment of this kind of tumor in the future (Table 3). This evidence concerns the gene TOPAZ1 and neoplasm.
