CaseHPOFreeText: A 57-year-old Caucasian woman with an unremarkable past medical history presented with lumbar pain. Physical examination revealed a mass on the right flank. An FDG-PET scan revealed a renal mass highly suggestive of malignancy, signs of liver spread, and pelvic and lumbar spinal cord bone metastases. Open right radical nephrectomy was performed. The histopathologic report revealed Fuhrman grade 4 advanced ccRCC. New response assessment after 2 cycles of treatment revealed disease progression with new liver and bone lesions and clinical deterioration. In August 2015, a new solitary bone metastasis arose in the skull, whereas others remained with no change.

VariantEvidence: VHL and MTOR variants were not explicitly stated to be germline in the text but were not present in Supplementary eTable 1 where variants present in tumor/metastasis and absent in blood are listed. The number of tumor mutations (single nucleotide variants and indels) leading to nonsynonymous coding or loss-of-function (LOF) variants in the primary tumor was 160. Tumor mutations refer to those detected in the tumor but absent in the blood. In total, 116, 76, and 65 mutations were detected in each of the 3 tumor regions and from these, 41 were shared. Among the shared tumor mutations, 39 were missense variants and 2 were LOF variants caused by frameshifts. The variants affecting genes frequently mutated in ccRCC were detected in all tumor samples analyzed: VHL (c.263G>T; p.W88L), BAP1 (c.1359dup; p.E454Rfs*15), and MTOR (c.5920T>C; p.Y1974H). For a comprehensive list of somatic variants see Supplementary eTable1.
