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]

Collection Method: clinical testing

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 84 of the VHL protein (p.Val84Met). This variant is present in population databases (no rsID available, gnomAD 0.001%). This missense change has been observed in individuals with clinical features of von Hippel-Lindau syndrome (PMID: 17688370; external communication). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 428813). 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%. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on VHL function (PMID: 17906660). This variant disrupts the p.Val84 amino acid residue in VHL. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 8592333, 11331612, 16502427, 25078357). 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.V84M variant (also known as c.250G>A), located in coding exon 1 of the VHL gene, results from a G to A substitution at nucleotide position 250. The valine at codon 84 is replaced by methionine, an amino acid with highly similar properties. This alteration has been reported in an individual affected with bilateral pheochromocytoma diagnosed at ages 1 year and 4 years; of note, this individual's father was also diagnosed with pheochromocytoma at age 40; however, genetic testing was not performed on the father (Stanojevic BR et al. Neoplasma. 2007;54:402-6). It was also identified in a patient diagnosed with a pheochromocytoma at age 8, with recurrence of disease at age 26 (Eisenhofer G et al. Horm. Metab. Res. 2012 May;44(5):343-8). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the majority of available evidence to date, this variant is likely to be pathogenic. -
