Between 1994 and 2001, the Dutch VHL working group conducted DNA analysis on 146 probands with VHL-associated manifestations. DNA of probands was extracted from peripheral blood samples. Exons 1, 2 and 3 of the VHL gene and their flanking untranslated and intronic coding sequences were amplified by PCR and subjected to semi-automated sequence analysis. Screening for structural rearrangements, including deletions, involving the VHL gene was performed by Southern blot analysis and the multiplex ligation-dependent probe amplification (MLPA) assay. Deletions encompassing the entire VHL gene were confirmed by FISH analysis on lymphocytes from affected individuals. VHL mutations were identified in 43 families. This mutation (c.452T>C) was detected in a VHL patient with CNS hemangioblastomas and renal cell carcinoma (family no. 11). This was published in a future publication: PMID: 32179488.

A cohort of 141 patients with hemangioblastomas of the central nervous system was analyzed. 81 patients had germline mutations in the VHL gene, analyzed through peripheral blood by Southern blotting and SSCP analysis. This missense mutation (c.452T>C) was recorded in the paper as c.665T>C due to a difference in transcript sequence. It was found in 2 patients with hemangioblastomas of the central nervous system. Any family information or relations is unknown. No other phenotypes described. This (member) was published in a future publication: PMID: 32179488.
