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]

VHL nonsense variant Q195* (c.583C>T) is pathogenic for Von Hippel Landau Disease. VHL variant Q195* (c.583C>T) introduces an early stop codon resulting in a truncated protein. Loss of function VHL variants have been implicated with pathogenicity for Von Hippel Landau disease (PVS1), and this variant has been observed in patients with symptoms and family history highly characteristic of Von Hippel Landau disease (PP4). The variant does not appear in the gnomAD population database (PM2). -

The p.Q195* pathogenic mutation (also known as c.583C>T), located in coding exon 3 of the VHL gene, results from a C to T substitution at nucleotide position 583. This changes the amino acid from a glutamine to a stop codon within coding exon 3. This pathogenic mutation has been reported in numerous families diagnosed with von Hippel-Lindau (VHL) syndrome (Crossey PA et al. Hum Mol Genet. 1994 Aug;3(8):1303-8; Hes FJ et al. Clin Genet. 2007 Aug;72(2):122-9; Losonczy G et al. BMC Med Genet. 2013 Jan 8;14:3). This mutation has also been reported in one individual diagnosed with a nonsyndromic pheochromocytoma (Neumann HP et al. N Engl J Med. 2002 May 9;346(19):1459-66). Note that this alteration is also referred to as c.796C>T in published literature. This alteration is expected to result in loss of function by premature protein truncation. As such, this alteration is interpreted as a disease-causing mutation. -
