Von Hippel-Lindau syndrome Pathogenic:3

Variant summary: VHL c.548C>A (p.Ser183X) results in a premature termination codon in the last exon that is not expected to cause nonsense mediated decay (NMD), but removes a part of the 213 amino acid long protein, eliminating a portion of the alpha domain (amino acids 156-204; IPR024048). Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 251414 control chromosomes (gnomAD). c.548C>A has been reported in the literature in multiple individuals affected with Von Hippel-Lindau Syndrome (e.g. Glasker_1999, Erlic_2010, Reich_2021). These data indicate that the variant is very likely to be associated with disease. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and all classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. -
Von Hippel-Lindau syndrome;C1837915:Chuvash polycythemia Pathogenic:1
This sequence change creates a premature translational stop signal (p.Ser183*) in the VHL gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 31 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 individuals with von Hippel-Lindau (VHL) syndrome (PMID: 8707293, 10567493, 11309459). It has also been observed to segregate with disease in related individuals. This variant is also known as c.761C>A. ClinVar contains an entry for this variant (Variation ID: 2215). This variant disrupts a region of the VHL protein in which other variant(s) (p.Leu188) have been determined to be pathogenic (PMID: 7563486, 7987306, 8772572, 11331612, 16452184, 18567581, 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. For these reasons, this variant has been classified as Pathogenic. -

Hereditary cancer-predisposing syndrome Pathogenic:1
The p.S183* pathogenic mutation (also known as c.548C>A), located in coding exon 3 of the VHL gene, results from a C to A substitution at nucleotide position 548. This changes the amino acid from a serine to a stop codon within coding exon 3. This alteration has been reported in multiple individuals with von Hippel-Lindau disease (Whaley JM et al. Am J Hum Genet, 1994 Dec;55:1092-102; Hes FJ et al. Clin Genet, 2007 Aug;72:122-9; Dandanell M et al. BMC Med Genet, 2012 Jul;13:54; Pilotto E et al. Cancers (Basel), 2021 Dec;14:). Of note, this alteration is also referred to as "761C>A" in the literature. This alteration occurs at the 3' terminus of the VHL gene, is not expected to trigger nonsense-mediated mRNA decay, and only impacts the last 31 amino acids of the protein. However, premature stop codons are typically deleterious in nature, the impacted region is critical for protein function, and a significant portion of the protein is affected (Ambry internal data). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -
