Single nucleotide polymorphism (SNP) was responsible for such variants, and single nucleotide variants (SNVs) mostly occurred as C > A and C > T. However, the role of PCDH15, MUC17, RPIL1, DAMTS12, and PAPPA219 expressed in a tumor microenvironment remains to be studied. The gene discussed is MUC17; the disease is neoplasm.
