Case: M, 61Y0M, Ethnicity Unknown

DiseaseAssertion: assumed VHL

FamilyInfo: Positive: the patient’s sister also presented with the germline c.562C>G mutation, and metastatic lobular breast carcinoma. In a family pedigree, 10 additional members affected with cancer were displayed. This included both of their parents: father with lung cancer, mother with skin cancer, additional sister with breast cancer, brother with melanoma. Lastly, his two sons presented with skin cancer, however no description of their genotyping. See Fig. 3.

CasePresentingHPOs: HP:0006770; HP:0001028 (Clear cell renal cell carcinoma, hemangioma)

CaseHPOFreeText: He presented in 2012 (52Y) with worsening lower abdominal discomfort (CT scan revealed a right renal solid mass of renal cell carcinoma). A right renal nephrectomy was done, confirming ccRCC. 4 years later, new lung nodules and an enhancing lesion in the L1 vertebral body was found (metastatic ccRCC). Additionally, in 2020, a pancreatic lesion present on his scans was presumed to be a metastatic RCC lesion (consistent with an atypical hemangioma).

Variant: p.L188V (c.562C>G)

LegacyVariant: N/A

CaseProblemVariantFreeText: In 2013, somatic next generation sequencing (NGS) testing using a panel of 447 cancer genes (OncoPanel, BWH Pathology, MA, USA) was performed on the resected renal specimen. This revealed the following variants: VHL p.Leu188Val (c.562C>G), CHEK2 p.Val395Leu (c.1183G>C), VHL p.Ala149Thr (c.445G>A) variant, and several copy number losses including a large single-copy deletion in 3p. 6 years later, germline testing revealed a heterozygous germline VHL p.Leu188Val variant, a CHEK2 and ERCC4 mutation.

CaseHPOFreeText: At 12 years old, a female patient presented with fever and headache with high blood pressure. Upon a CT scan, a right adrenal tumor was detected and tumor resection was performed, revealing a pathological diagnosis of pheochromocytoma. Upon further review, a CT scan found multiple tumors in left adrenal and paraganglion region zones with round nodular shadows. She was diagnosed with pheochromocytoma (PCC) and paraganglioma (PGL). A lung puncture revealed a carcinoid and a pancreatic puncture indicates a neuroendocrine tumor. Left adrenalectomy and PPGL resection was performed and diagnosis was pathologically confirmed
