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).

SupplementalData: Yes

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.

Case: M, 66Y0M, Korean

DiseaseAssertion: VHL

FamilyInfo: N/A

CohortInfo: 55 patients treated at Asan Medical Center in Korea treated between January 1995 and February 2013 clinically diagnosed with VHL disease and presenting with pancreatic lesions.

CasePresentingHPOs: HP:0001737, HP:0030405 (Pancreatic cysts, Pancreatic endocrine tumor)

CaseHPOFreeText: At age 56, the patient had a serous cystadenoma of the pancreas and a pancreatic endocrine tumour. A Pylorus-preserving pancreaticoduodenectomy was performed and the largest tumour resected was 40 mm. On follow up 170 months later the patient had no evidence of disease.
