Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000002301	SCV000053265	pathogenic	Von Hippel-Lindau syndrome	2019-07-22	criteria provided, single submitter	clinical testing	Variant summary: VHL c.481C>T (p.Arg161X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 251440 control chromosomes. c.481C>T has been extensively reported in the literature spanning over two decades to co-segregate with disease among multiple affected individuals from families with Von Hippel-Lindau Syndrome (example, Loeb_1994, Zbar_1996, Maher_1996, Li_1998, Cybulski_2002, Ruiz-Llorente_2004, Gallou_2004). These data indicate that the variant is very likely to be associated with disease. No experimental evidence demonstrating an impact on protein function was ascertained during this review. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.

Labcorp Genetics (formerly Invitae), Labcorp	RCV000791367	SCV000553380	pathogenic	Chuvash polycythemia; Von Hippel-Lindau syndrome	2023-12-29	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Arg161*) in the VHL gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 53 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 individual(s) with von Hippel-Lindau syndrome (PMID: 7987306, 8956040, 9452032, 9829911, 9829912, 10567493, 12114495, 14722919, 15300849, 18446368, 19270817, 21362373, 24206762, 24301059, 25867206). In at least one individual the variant was observed to be de novo. It has also been observed to segregate with disease in related individuals. This variant is also known as c.694C>T. ClinVar contains an entry for this variant (Variation ID: 2217). This variant disrupts the p.Arg161 amino acid residue in VHL. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 7728151, 9829911, 12000816, 14767570, 15300849, 20120764, 21362373, 23842656, 24707167). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
Ambry Genetics	RCV000492225	SCV000580965	pathogenic	Hereditary cancer-predisposing syndrome	2023-04-17	criteria provided, single submitter	clinical testing	The p.R161* pathogenic mutation (also known as c.481C>T) located in coding exon 3 of the VHL gene, results from a C to T substitution at nucleotide position 481. This changes the amino acid from an arginine to a stop codon within coding exon 3. This mutation has been reported in several individuals with personal and family histories of Von Hippel-Lindau (VHL) syndrome (Cho HJ et al. J Korean Med Sci. 2009 Feb;24:77-83; Siu WK et al. Chin. Med. J. 2011 Jan;124:237-41; Zbar B et al. Hum. Mutat. 1996;8:348-57; Papathomas TG et al. Mod. Pathol. 2015 Jun;28:807-21; Wong M et al. Chin J Cancer. 2016 Aug;35:79; Sriphrapradang C et al. Clin Med Insights Endocrinol Diabetes. 2017 Apr;10:1179551417705122). A 48 year old male with bilateral renal clear cell carcinoma and a clinical diagnosis of VHL was found to be a mosaic carrier of this pathogenic mutation (Coppin L et al. Eur. J. Hum. Genet. 2014 Sept;22:1149-52). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	RCV000161091	SCV000884875	pathogenic	not provided	2018-04-16	criteria provided, single submitter	clinical testing	The VHL c.481C>T; p.Arg161Ter variant (rs5030818), also known as c.694C>T for traditional nomenclature, is reported multiple times in the literature in association with von Hippel-Lindau disease (see Cybulski 2002, Glavac 1996, Nordstrom-O'Brien 2010, Stolle 1998, Zbar 1996). This variant is reported as pathogenic by multiple laboratories in ClinVar (Variation ID: 2217), and it is absent from the general population databases (1000 Genomes Project, Exome Variant Server, and Genome Aggregation Database). This variant induces an early termination codon and is predicted to result in a truncated protein or mRNA subject to nonsense-medicated decay. Based on available information, this variant is considered to be pathogenic. REFERENCES Cybulski C et al.
