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]

ACMG classification

Verdict is Pathogenic. Variant got 18 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 3-10142064-C-T is Pathogenic according to our data. Variant chr3-10142064-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 223164.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr3-10142064-C-T is described in Lovd as [Pathogenic].

This sequence change creates a premature translational stop signal (p.Gln73*) in the VHL gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in VHL are known to be pathogenic (PMID: 8956040, 12202531). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individuals with von Hippel-Lindau disease (PMID: 7728151, 27527340). This variant is also known as a stop at codon 144. ClinVar contains an entry for this variant (Variation ID: 223164). For these reasons, this variant has been classified as Pathogenic. -
