Variant summary

Our verdict is Pathogenic. The variant received 13 ACMG points: 13P and 0B. PVS1PM2_SupportingPS4

This summary comes from the ClinGen Evidence Repository: The variant NM_000551.4(VHL):c.263G>A (p.Trp88Ter) in VHL is a truncating variant. This variant causes a premature stop codon in a biologically-relevant-exon predicted to undergo nonsense mediated decay in a gene in which loss-of-function is an established disease mechanism (PVS1). This variant has been identified in at least 9 unrelated probands (and other related family members not counted within each) all meeting Danish VHL criteria, from literature evaluated in both CIViC and Hypothes.is VHL datasets. CIViC EIDs (https://civicdb.org): 8292;7606;5776;9374;6806;6538. This corresponds to Strong evidence (5-15 probands) (PS4). 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 syndrome (VHL syndrome) 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/CA020197/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]
