Von Hippel-Lindau syndrome Pathogenic:1
Variant summary: VHL c.581T>G (p.Val194Gly) 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. The variant was absent in 251414 control chromosomes. c.581T>G has been reported in the literature in individuals affected with Von Hippel-Lindau Syndrome and was shown to segregate with disease in at-least one family evaluated at our partner laboratory (example, Kawashima_2014 and internal data). At-least one family reported in the literature describes the variant as inherited from an unaffected father although the loss of heterozygosity was demonstrated in tumors of the affected proband (Kawashima_2014). 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 has been ascertained in the context of this evaluation (PMID: 24518179). ClinVar contains an entry for this variant (Variation ID: 428810). Based on the evidence outlined above, the variant was classified as likely pathogenic. -
Von Hippel-Lindau syndrome;C1837915:Chuvash polycythemia Pathogenic:1
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. ClinVar contains an entry for this variant (Variation ID: 428810). This missense change has been observed in individuals with clinical features of von Hippel-Lindau syndrome (PMID: 24518179; Invitae). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces valine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 194 of the VHL protein (p.Val194Gly). For these reasons, this variant has been classified as Pathogenic. -
Hereditary cancer-predisposing syndrome Pathogenic:1
The p.V194G variant (also known as c.581T>G), located in coding exon 3 of the VHL gene, results from a T to G substitution at nucleotide position 581. The valine at codon 194 is replaced by glycine, an amino acid with dissimilar properties. This alteration was first reported in a 17 year-old female patient presenting with malignant pheochromocytoma. Tissue analyses conducted on three distinct tumors from this patient all demonstrated loss of heterozygosity. This alteration was also detected in this patient's father, who was reported to be unaffected at the time of the study (Kawashima S et al. Endocr Pract. 2014 Jun;20(6):e96-e101). This alteration was found to segregate with disease in a family with clinical history suggestive of VHL (Ambry internal data). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the majority of available evidence to date, this variant is likely to be pathogenic. -
