In a study of 114 unrelated VHL affected families, germline mutations in the VHL gene were identified in 85 of the families. VHL mutations were detected in affected family members, but not in unaffected family members or 96 normal individuals, however it seems unaffected family members were not tested genetically for the mutations. Mutations in the VHL gene were detected by SSCP and DNA sequencing. Haplotypes were determined with four microsatellite polymorphic probes. The missense mutation L184P (c.551T>C) (In the paper noted as nucleotide position 764 and codon position 255 due to old reference transcript), was found in 2 individuals in family 3708. Both individuals were identified with renal cell carcinoma and one also presented with a CNS hemangioblastoma. Additional information regarding the family information, including a pedigree, were not provided. ACMG evidence codes: 'flag for PP4' since the patients phenotype and family history is consistent with VHL, 'flag for PP1' because there is co-segregation of variant with the phenotype in two members of the family.

Germline mutational data on VHL was gathered from various countries to assess variation in germline mutations that produce disease within different populations. Families were grouped according to three possible outcomes of disease: renal cell carcinoma without pheochromocytoma, renal cell carcinoma with pheochromocytoma, or pheochromocytoma alone. SSCP and denaturing gradient gel electrophoresis identified mutations in 300/469 (63%) of families affected with VHL. This germline familial VHL mutation (L184P (c.551T>C)) was taken from the National Cancer Institute database, with an unknown number of members belonging to Family ID 3708NCI. It was reported in the paper as c.764T>C due to a difference in transcript reference. As reported in Table 3, this mutation is found in VHL families without pheochromocytoma, and with renal cell carcinoma. Later publications reference this cohort as being reported in PMID: 7728151.
