Among the variants detected in exome sequencing from the tumor specimen, those in SCN1B, PPP1R3A, GRID2, APBA2, ZNF142, ZYG11A, RBFOX1, TCF7L1, TEX13B, and DSCAML1 were validated by Sanger sequencing, and the details of these 10 candidate genes are provided in Table 2. Here, GRID2 is linked to neoplasm.
