Variant summary
Our verdict is Uncertain significance. The variant received 5 ACMG points: 6P and 1B. PM1PM2PP3_ModerateBP6
The NM_000551.4(VHL):c.553T>A(p.Tyr185Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000131 in 152,184 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y185C) has been classified as Uncertain significance.

Von Hippel-Lindau syndrome;C1837915:Chuvash polycythemia Uncertain:1
This sequence change replaces tyrosine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 185 of the VHL protein (p.Tyr185Asn). This variant is present in population databases (rs768390987, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with VHL-related conditions. ClinVar contains an entry for this variant (Variation ID: 1385557). 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%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Von Hippel-Lindau syndrome Benign:1
This variant is considered likely benign. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance. -
