Von Hippel-Lindau syndrome Pathogenic:2

Variant summary: VHL c.393C>A (p.Asn131Lys) results in a non-conservative amino acid change located in the von Hippel-Landau (pVHL) tumor suppressor protein domain (IPR022772) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. At-least one additional variant at the same codon (c.392A>G, p.Asn131Ser) has been observed in individuals with Von Hippel-Lindau Syndrome supporting the critical relevance of this residue to VHL protein function. The variant was absent in 251688 control chromosomes. c.393C>A has been reported in the literature in individuals affected with Von Hippel-Lindau Syndrome (example, Olschwang_1998, Gallou_2004, Imanaka_2006, Jonasch_2011, Majchrzak_2011, Krauss_2018). At-least one of these publications reported a family with multiple affected family members, although only the affected proband was genotyped (Majchrzak_2011). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 15300849, 17001110, 22105611, 29748190, 21384277, 9829912). ClinVar contains an entry for this variant (Variation ID: 420074). Based on the evidence outlined above, the variant was classified as pathogenic. -
Von Hippel-Lindau syndrome;C1837915:Chuvash polycythemia Pathogenic:1
This missense change has been observed in individuals with von Hippel-Lindau syndrome (PMID: 9829912, 15300849, 21384277). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 131 of the VHL protein (p.Asn131Lys). ClinVar contains an entry for this variant (Variation ID: 420074). For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Asn131 amino acid residue in VHL. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 10761708, 17001110, 21384277, 27527340; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt VHL protein function. -
not provided Pathogenic:1
Not observed in large population cohorts (Lek 2016); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 22105611, 15300849, 18836774, 9829912, 17661816, 24166983, 20660572, 17696210, 20151405, 19238077, 21384277, 29748190) -
Hereditary cancer-predisposing syndrome Pathogenic:1
The p.N131K variant (also known as c.393C>A), located in coding exon 2 of the VHL gene, results from a C to A substitution at nucleotide position 393. The asparagine at codon 131 is replaced by lysine, an amino acid with similar properties. This variant was reported in individuals and families with features consistent with von Hippel-Lindau syndrome (VHL) (Olschwang S et al. Hum Mutat, 1998;12:424-30; Gallou C et al. Hum Mutat, 2004 Sep;24:215-24; Majchrzak K et al. Neurol Sci, 2011 Jun;32:491-6; Jonasch E et al. Ann Oncol, 2011 Dec;22:2661-2666; Krauss T et al. Endocr Relat Cancer, 2018 Sep;25:783-793; Gao L et al. Genes (Basel), 2024 Sep;15; Ambry internal data). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the majority of available evidence to date, this variant is likely to be pathogenic. -
