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]

Collection Method: clinical testing

This premature translational stop signal has been observed in individual(s) with clinical features of von Hippel-Lindau disease (PMID: 23298237, 33720516). For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the VHL protein in which other variant(s) (p.Leu188Val) have been determined to be pathogenic (PMID: 7563486, 7987306, 8772572, 19228690, 23772956). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Tyr185*) in the VHL gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 29 amino acid(s) of the VHL protein.
