Variant summary
Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4_ModerateBP6
The NM_000551.4(VHL):c.5C>T(p.Pro2Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000138 in 1,535,874 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign 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. P2H) has been classified as Uncertain significance.

Von Hippel-Lindau syndrome Uncertain:3Benign:1
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
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. -
This missense variant replaces proline with leucine at codon 2 of the VHL protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in two individuals affected with erythrocytosis (PMID: 29790589). This variant has been identified in 14/171178 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
This missense variant replaces proline with leucine at codon 2 of the VHL protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373).

not specified Uncertain:2
Variant summary: The VHL c.5C>T (p.Pro2Leu) variant involves the alteration of a non-conserved nucleotide. 2/3 in silico tools predict a benign outcome for this variant (SNPsandGO not captured due to low reliability index). This variant was found in 12/164682 control chromosomes, predominantly observed in the European (Non-Finnish) subpopulation at a frequency of 0.000189 (12/63398). This frequency is about 9 times the estimated maximal expected allele frequency of a pathogenic VHL variant (0.0000208), suggesting this is likely a benign polymorphism found primarily in the populations of European (Non-Finnish) origin. Multiple clinical diagnostic laboratories/reputable databases classified this variant as uncertain significance. The variant of interest has not, to our knowledge, been reported in affected individuals via publications nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as a VUS - possibly benign variant, until additional evidence becomes available. -

This variant is associated with the following publications: (PMID: 29790589, 10612827) -
Hereditary cancer-predisposing syndrome Benign:2
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

VHL-related disorder Uncertain:1
The VHL c.5C>T variant is predicted to result in the amino acid substitution p.Pro2Leu. This variant has been reported as a variant of uncertain significance in the heterozygous state in two patients with hereditary erythrocytosis (Oliveira et al. 2018. PubMed ID: 29790589). This variant is reported in 0.019% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-10183536-C-T) and has conflicting interpretations of likely benign and uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/182981/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
