Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PM1PM2PM5PP3_StrongPP5_Very_Strong
The NM_000551.4(VHL):c.257C>G(p.Pro86Arg) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P86H) has been classified as Likely pathogenic.

Von Hippel-Lindau syndrome;C1837915:Chuvash polycythemia Pathogenic:1
This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 86 of the VHL protein (p.Pro86Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with von Hippel-Lindau syndrome (PMID: 9829911, 11257211, 17024664, 19408298). ClinVar contains an entry for this variant (Variation ID: 223170). 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 with a positive predictive value of 95%. This variant disrupts the p.Pro86 amino acid residue in VHL. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 9829912, 10205047, 22799452, 27034144, 27057652, 27527340). 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. -
Hereditary cancer-predisposing syndrome Pathogenic:1
The p.P86R pathogenic mutation (also known as c.257C>G), located in coding exon 1 of the VHL gene, results from a C to G substitution at nucleotide position 257. The proline at codon 86 is replaced by arginine, an amino acid with dissimilar properties. This variant has been reported in numerous families with a diagnosis of Von Hippel-Lindau syndrome (VHL) (Stolle C et al. Hum. Mutat. 1998;12:417-23; Rothberg PG et al. Mol. Diagn. 2001 Mar;6:49-54; Ong KR et al. Hum. Mutat. 2007 Feb;28:143-9; Liu SJ et al. Genet. Med. 2018 10;20:1266-1273). Of note, the p.P86L (c.257C>T) alteration has also been reported as p.P157L (c.470C>T) in some literature. Several other alterations at the same codon (p.P86A, p.P86L, and p.P86S) have been detected in individuals with VHL syndrome suggesting this codon may represent a mutation hotspot. 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. -
