Genes affected
VHL (HGNC:12687): (von Hippel-Lindau tumor suppressor) This gene encodes a component of a ubiquitination complex. The encoded protein is involved in the ubiquitination and degradation of hypoxia-inducible-factor (HIF), which is a transcription factor that plays a central role in the regulation of gene expression by oxygen. In addition to oxygen-related gene expression, this protein plays a role in many other cellular processes including cilia formation, cytokine signaling, regulation of senescence, and formation of the extracellular matrix. Variants of this gene are associated with von Hippel-Lindau syndrome, pheochromocytoma, erythrocytosis, renal cell carcinoma, and cerebellar hemangioblastoma. [provided by RefSeq, Jun 2022]

Review Status: criteria provided, single submitter

This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 70 of the VHL protein (p.Glu70Gly). This variant is present in population databases (rs786202857, gnomAD 0.003%). This missense change has been observed in individuals with clinical features of von Hippel-Lindau syndrome (internal data). ClinVar contains an entry for this variant (Variation ID: 186316). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt VHL protein function with a positive predictive value of 95%. This variant disrupts the p.Glu70 amino acid residue in VHL. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 9829912, 17661816, 19270817, 19408298, 25078357, 25562111, 25715769, 27439424; internal data). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -

The p.E70G variant (also known as c.209A>G), located in coding exon 1 of the VHL gene, results from an A to G substitution at nucleotide position 209. The glutamic acid at codon 70 is replaced by glycine, an amino acid with similar properties. This variant has been reported in an individual with a pheochromocytoma and was classified as variant of unknown significance by authors (Parisien-La Salle S et al. Clin Endocrinol (Oxf), 2022 Jun;96:803-811). This variant was determined to be functionally intermediate in one saturation genome editing assay (Buckley M et al. Nat Genet, 2024 Jul;56:1446-1455). Another variant at the same codon, p.E70K (c.208G>A), has been identified in individual(s) with features consistent with von Hippel-Lindau syndrome and has been shown to cause a modest reduction in the ability of the VHL protein to bind with the alpha subunit of the hypoxia-inducible transcription factor (Olschwang S et. al, Hum. Mut. 1998;12:424-30; Hes FJ et. al. Clin. Genet. 2007 Aug;72:122-9; Cho HJ et al. J Korean Med Sci. 2009 Feb;24:77-83; Miller F et al. J Biol Chem. 2005 Mar;280:7986-96). This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
