Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PVS1 PS4_Supporting PM2_Supporting

This summary comes from the ClinGen Evidence Repository: The NM_000551.3(VHL):c.586A>T (p.Lys196Ter) variant in VHL is a truncating mutation that terminates the VHL protein at position 196, which resides in the second Beta domain (PVS1). One proband has been identified with this variant, and has a family history of VHL and clinical features of VHL (CNS hemangioblastoma, renal cell carcinoma in a female of reported age 17 (Hwang et al (PMID:25078357)). One case meeting Danish VHL criteria equates to supporting evidence (PS4_Supporting). This variant is absent from gnomAD v4.1.0 (PM2_Supporting). In summary, this variant meets the criteria to be classified as Pathogenic for autosomal-dominant von Hippel-Lindau disease (VHL disease) based on the ACMG/AMP criteria applied, as specified by the ClinGen VHL VCEP Version 1.0 (Specifications approval date: 02/26/2024. Variant Approval Date 06/25/2024). LINK:https://erepo.genome.network/evrepo/ui/classification/CA020507/MONDO:0008667/078

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 creates a premature translational stop signal (p.Lys196*) in the VHL gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 18 amino acid(s) of the VHL protein. This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with von Hippel-Lindau syndrome (PMID: 19333546). ClinVar contains an entry for this variant (Variation ID: 196284). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. This variant disrupts a region of the VHL protein in which other variant(s) (p.Leu198Pro) have been determined to be pathogenic (PMID: 24555745, 27539324, 29124493). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
