Molecular analysis for 3 highlighted patients. A, Path (red), LP (gold), and VUS (Blue) variants identified by TSO500 in colon adenocarcinoma from 15-year-old male. Pathogenic germline mutations were identified in MLH1 (c.156del p.Glu53Argfs*4) and APC (c.3329C>A, p.Ser1110*) and VUS in SMAD4 (c.947A>G, p.Asn316Ser; hatched bars). B, Variants identified by TSO500 in a malignant melanotic schwannoma from a 36-year-old female, with Path mutations in NF1 (c.276dupA, p.C93fs*14) and PRKAR1A (c.207_208delGA, p.K70fs*11) and LP variant in SETD2 (c.4405dupA, p.M1469fs*6).C, Variants identified in two lymph node metastases collected 1 year apart from a carcinoma of unknown primary in a 75-year-old male (purple collected first, green collected second). VUS with higher percentage VAF (>45%) were identified in both samples (NCOR1, MST1R, ABL2, ROS1, ESR1, FAT1, POLE, NTRK3, and GEN1), as well as low VAF (∼6%) VUS in ZNF703. Pathogenicity of variants is indicated in y-axis label.
