Variant summary
Our verdict is Benign. The variant received -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

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
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. ACMG/AMP Criteria applied: BS1, BS4, BP4. -

Von Hippel-Lindau syndrome Benign:7
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. -
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.

Hereditary cancer-predisposing syndrome Benign:2
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. -
