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]

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 93 of the VHL protein (p.Gly93Ser). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with von Hippel-Lindau (VHL) syndrome (PMID: 8707293, 9329368, 12000816, 17661816, 17922902). In at least one individual the variant was observed to be de novo. It has also been observed to segregate with disease in related individuals. This variant is also known as c.490G>A. ClinVar contains an entry for this variant (Variation ID: 2237). 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%. For these reasons, this variant has been classified as Pathogenic. -

This variant has not been reported in large, multi-ethnic general populations. (http://gnomad.broadinstitute.org) This variant has been identified in multiple unrelated individuals with VHLS and/or pheochromocytoma and has been reported to occur de novo in multiple individuals. This variant is also referred to as c.490G>A in published literature. Polyphen and MutationTaster predict this amino acid change may be damaging to the protein. -

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.G93S pathogenic mutation (also known as c.277G>A), located in coding exon 1 of the VHL gene, results from a G to A substitution at nucleotide position 277. The glycine at codon 93 is replaced by serine, an amino acid with similar properties. This alteration has been reported in families with Von Hippel-Lindau (VHL) with pheochromocytomas as well as in individuals with isolated pheochromocytomas (Zbar B et al. Hum Mutat. 1996;8(4):348-57; Neumann HP et al. N Engl J Med. 2002 May 9;346(19):1459-66). Of note, this alteration is also known as c.490G>A in published literature. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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 supporting evidence, this alteration is interpreted as a disease-causing mutation. -
