Case: M, 57Y0M, Ethnicity Unknown

DiseaseAssertion: VHL

FamilyInfo: This patient had a father that was assumed to have the c.406T>C germline mutation of the VHL gene but was not confirmed genetically. His father presented with renal cell carcinoma and died at 47Y.

VariantEvidence: Variant reference sequence is unclear in the current paper. After consulting the SickKids patient database, and finding the protein change to be recorded as: p.Ser65Pro, it was concluded that the current paper reported the cDNA change according to the legacy reference sequence (AF010238.1) and was mapped to c.193T>C (NM_000551.3).

Molecular and clinical analysis of 126 French VHL families tested for renal involvement revealed 92 different mutations. 90 of these families had renal involvement. The p.S65P (c.193T>C) germline variant of the VHL gene was detected in a family (ID 185). Member 9359 has unknown renal involvement. Member 9357 presented with mild renal disease. Member 1052 had no renal involvement. Member 3979 has moderate renal disease (RCC). The paper states that this family is previously reported in PMID 12202531, where 2 patients with this mutation are reported but relation between patients is unknown.

GroupInfo: 4 members of this family are reported as carrying the c.193T>C germline variant of the VHL gene. Member 9359 has unknown renal involvement. Member 9357 presented with mild renal disease. Member 1052 had no renal involvement. Member 3979 has moderate renal disease (RCC). Families were recruited from the French VHL Registry. Enrolment in the study required identification of the germline VHL mutation (currently 85% of the families included in the French VHL Registry) and available data regarding renal phenotype. A total of 126 families fulfilled these criteria.

GroupPresentingHPOs: HP:0009726; HP:0005584 (Renal neoplasm, Renal cell carcinoma)

GroupHPOFreeText: Mild renal disease (simple renal cyst, multicystic kidney[s], small lesion [less than 10 mm in size] of unknown significance, or small solid tumor without indication for surgical removal [less than 30 mm in size]). Moderate renal disease (less than five solid lesions requiring surgical treatment, either unilateral or bilateral).
