Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BA1

This summary comes from the ClinGen Evidence Repository: The variant NM_000551.3(VHL):c.74C>T (p.Pro25Leu) in VHL is a missense variant occurring prior to the second start site. The GroupMax Filtering Allele Frequency (95% CI) in gnomAD v4.1.0 is 0.005329 (6211/1141350 from European, Non-Finnish Population). This is higher than the ClinGen VHL VCEP threshold of >=0.000156 (0.0156%) threshold expected for VHL disease (BA1). In summary, this variant meets the criteria to be classified as Benign for autosomal-dominant von Hippel-Lindau disease (VHL disease) based on the ACMG/AMP criteria applied, as specified by the ClinGen VHL VCEP Version 1.0 (Specifications approval date: 02/26/2024. Variant Approval Date 06/25/2024). LINK:https://erepo.genome.network/evrepo/ui/classification/CA020538/MONDO:0008667/078

Genes affected

VHL (HGNC:12687): (von Hippel-Lindau tumor suppressor) This gene encodes a component of a ubiquitination complex. The encoded protein is involved in the ubiquitination and degradation of hypoxia-inducible-factor (HIF), which is a transcription factor that plays a central role in the regulation of gene expression by oxygen. In addition to oxygen-related gene expression, this protein plays a role in many other cellular processes including cilia formation, cytokine signaling, regulation of senescence, and formation of the extracellular matrix. Variants of this gene are associated with von Hippel-Lindau syndrome, pheochromocytoma, erythrocytosis, renal cell carcinoma, and cerebellar hemangioblastoma. [provided by RefSeq, Jun 2022]

Collection Method: clinical testing

The p.Pro25Leu variant in VHL is classified as likely benign because it has been identified in 0.66% (23/3470) of Ashkenazi Jewish chromosomes and 0.45% (304/68032) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant was shown not to segregate with disease in 2 affected individuals from 2 families. Computational prediction tools and conservation analyses suggest that this variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity.

The variant NM_000551.3(VHL):c.74C>T (p.Pro25Leu) in VHL is a missense variant occurring prior to the second start site. The GroupMax Filtering Allele Frequency (95% CI) in gnomAD v4.1.0 is 0.005329 (6211/1141350 from European, Non-Finnish Population). This is higher than the ClinGen VHL VCEP threshold of >=0.000156 (0.0156%) threshold expected for VHL disease (BA1).

Illumina Laboratory Services, Illumina

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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 and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as 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. -
