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 missense variant replaces proline with leucine at codon 81 of the VHL protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in multiple individuals affected with VHL-associated tumor or have a VHL diagnosis (PMID: 17102082, 21389259, 22241717, 24134185, 33219105). This variant has been identified in 1/229958 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Based on the available evidence, this variant is classified as Likely Pathogenic. -

Variant summary: VHL c.242C>T (p.Pro81Leu) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4.3e-06 in 229958 control chromosomes. c.242C>T has been reported in the literature in multiple individuals affected with isolated pheochromocytoma and/or paraganglioma and no other features of von Hippel Lindau syndrome (examples: Castellano_2006, Formenti_2011, Piccini_2012, Kim_2013, Lessi_2014,Dilzell_2016, Kim_2022). These data indicate that the variant is very likely to be associated with disease. The following publications have been ascertained in the context of this evaluation (PMID: 17102082, 21389259, 24134185, 24446253, 22241717, 33219105). ClinVar contains an entry for this variant (Variation ID: 36899). Based on the evidence outlined above, the variant was classified as pathogenic. -

Collection Method: clinical testing

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 81 of the VHL protein (p.Pro81Leu). This variant is present in population databases (rs193922608, gnomAD 0.003%). This missense change has been observed in individuals with clinical features of von Hippel-Lindau disease (type 2C: pheochromocytoma and paraganglioma) (PMID: 17102082, 21389259, 22241717, 24134185, 27730413; internal data). ClinVar contains an entry for this variant (Variation ID: 36899). 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. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.P81L variant (also known as c.242C>T), located in coding exon 1 of the VHL gene, results from a C to T substitution at nucleotide position 242. The proline at codon 81 is replaced by leucine, an amino acid with very few similar properties. This alteration has been reported in multiple individuals with diagnoses consistent with of von Hippel-Lindau syndrome (VHL), but not clearly meeting clinical diagnostic criteria; including an individual with a right carotid body paraganglioma (Piccini V et al. Endocr Relat Cancer. 2012 Apr 10;19(2):149-55), a patient with a left para-adrenal paraganglioma (Castellano M et al. Ann N Y Acad Sci. 2006 Aug;1073:156-65), an individual diagnosed with VHL type 2C (Formenti F et al. FASEB J. 2011 Jun;25(6):2001-11), and an individual with pheochromocytoma at age 16 (Kim JH et al. Clin Genet, 2014 Nov;86:482-6). Further, another alteration at this codon, p.P81S (c.241C>T) has been described both as a low-penetrance mutation in VHL type 1 families (Gläsker S et al. J. Neurol. Neurosurg. Psychiatr. 1999 Dec;67:758-62; Glavac D et al. Hum. Genet. 1996 Sep;98:271-80; Hes FJ et al. J. Med. Genet. 2000 Dec;37:939-43; Kondo K et al. Hum. Mol. Genet. 1995 Dec;4:2233-7; Yoshida M et al. Jpn J Cancer Res. 2000 Feb;90:204-212; Zbar B et al. Hum. Mutat. 1996;8:348-57; Alosi D et al. Curr. Genomics. 2017 Feb;18:93-103) and as a nonpathogenic alteration (Erlic Z et al. J Clin Endocrinol Metab. 2010 Jan;95:308-13). 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 majority of available evidence to date, this variant is likely to be pathogenic; however, individuals may not present with classic von Hippel-Lindau syndrome. Clinical correlation is advised. -
