The variant is located in a mutational hotspot (COSMIC database). The in silico tool REVEL predicts a deleterious effect on protein function, and functional studies have shown mixed effects. Some functional studies have concluded that the variant behaves similar to the wild-type (Knauth 2009), whereas others suggest this variant may lead to reduced DNA damage response and resistance to ionizing radiation induced apoptosis (Li 2002, Desimone 2013). The Pro81Ser change has been reported in several individuals and families with Von Hippel Lindau-related cancers (Glavac 1996, Stolle 1998, Glasker 1999, Hes 2000, Weirich 2002, Erlic 2010, Haitz 2015, Alosi 2017). The Pro81Ser variant did not segregate with disease in a family with Von Hippel Lindau (Erlic 2009). In another family with several affected individuals, the variant was found to co-segregate in cis with another missense change in VHL (Weirich 2002). Since supporting evidence is conflicting, the clinical significance of this alteration remains unclear. It has therefore been classified as of uncertain significance.

A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.

This sequence change has been described in the gnomAD database with a frequency of 0.04% in the European sub-population (dbSNP rs104893829). The p.Pro81Ser change has been reported in individuals with Von-Hippel Lindau-related cancers (PMIDs: 28503092, 19906784, 11106358, 9829911, 12414898, 8634692; Glavac 1996, Glasker 1999, Haitz 2015). This sequence change has been identified in two families that also had a likely pathogenic VHL variant in cis with this sequence change (PMIDs: 19906784, 12414898), and one family with a large deletion of the entire VHL gene in trans with this sequence change, in which the p.Pro81Ser change did not segregate with disease (PMID: 19906784). The p.Pro81Ser change has also been identified in three unrelated individuals with hemangioblastoma or renal cell carcinoma (Haitz 2015; PMID: 28503092, 11106358). Relatives of these individuals who carried the sequence change were not affected. Functional studies have suggested both normal protein activity (PMID: 19228690), and lack of ubiquitination, reduced DNA damage response, and resistance to ionizing radiation-induced apoptosis (Li 2002; PMID: 23990666) in the presence of this sequence change. The p.Pro81Ser change affects a highly conserved amino acid residue located in a domain of the VHL protein that is known to be functional. The p.Pro81Ser substitution appears to be deleterious using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.Pro81Ser change remains unknown at this time.

Genetics and Molecular Pathology, SA Pathology	RCV000002321	SCV004175351	uncertain significance	Von Hippel-Lindau syndrome	2022-08-29	criteria provided, single submitter	clinical testing	The VHL c.241C>T variant is a single nucleotide change in exon 1/3 of the VHL gene, which is predicted to change the amino acid proline at position 81 in the protein to serine. This variant is situated at the alpha-beta domain interface (PM1). The population frequency is higher than expected for a disease-causing VHL variant (gnomAD 0.035%, 53/152206) (PM2 Not Met). This variant has been reported in several families and individuals with VHL-related syndromes, including RCC, hemangioblastoma, and paraganglioma (PMID: 28503092, 8707293, 9829911, 10567493, 11106358) (PS4). Erlic et al. (PMID: 19906784) reported an affected individual who had inherited this variant from his unaffected father, but who also had an in trans, de novo deletion of the entire VHL gene (BP2). Alosi et al. (PMID: 28503092) reported a kindred with 5 carriers of the variant and only one family member was affected with early onset renal clear cell cancer, suggesting that suggesting that the variant does not segregate with disease (BS4) or it may be a variant of variable penetrance. In silico tools suggest the impact of the variant on protein function is inconclusive. Functional studies have shown activity close to wildtype (PMID: 19228690), or a slight reduction to target protein binding with minimal impact to the protein complex functionality, except when in conjunction with another VHL variant (PMID: 22234250). The variant has been reported in dbSNP (rs104893829) and HGMD (CM951274). The variant has been reported with conflicting interpretations of pathogenicity by other diagnostic laboratories (ClinVar Variation ID:2233).
