The recorded framework is ClinGen VHL VCEP v1.1.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.
The applied criteria and their strengths are shown as assessed under the stated framework.
No pathogenic criterion marked as applied in the recorded assessment.
NM_000551.3:c.-77C>T has a GroupMax Filtering Allele Frequency of 0.0888 (8.88%) in gnomAD v4.1 and 0.0856 (8.56%) in gnomAD v2.1, far exceeding the VHL VCEP BA1 threshold of ≥0.0156% (≥1.56×10⁻⁴). This allele frequency is incompatible with a highly penetrant autosomal dominant disorder such as von Hippel-Lindau disease. The variant is also observed in 332 homozygotes in gnomAD v4.1.
NM_000551.3:c.-77C>T has a GroupMax Filtering Allele Frequency of 0.0888 (8.88%) in gnomAD v4.1, far exceeding the VHL VCEP BS1 threshold of ≥0.00156% (≥1.56×10⁻⁵). The allele frequency is too high for a rare disease like von Hippel-Lindau syndrome.
ClinGen VHL Expert Panel Specifications to the ACMG/AMP Variant Interpretation Guidelines for VHL Version 1.1.0 v1.1.0 criteria-combination framework: matched Rule17 (1 Benign.Stand Alone) with applied criteria: BA1 stand-alone benign, BS1 strong; maps to Benign.

gnomAD v4.1: 7,326 / 1,488,092 alleles. Recorded AF 0.00492308. Recorded homozygote count 332.
This variant is present in gnomAD v2.1 (AF= 0.0257254; MAF= 2.57254%, 805/31292 alleles, homozygotes = 36) and has highest observed frequency in the African/African American population (AF= 0.0908356; MAF= 9.08356%, 787/8664 alleles, homozygotes = 36); grpmax FAF= 0.0855752.

NM_000551.3:c.-77C>T meets BA1 (Stand-Alone) under VHL VCEP v1.1.0: GroupMax Filtering Allele Frequency of 8.88% in gnomAD v4.1 far exceeds the BA1 threshold of 0.0156%, establishing this variant as benign.
NM_000551.3:c.-77C>T also meets BS1 (Strong): GroupMax Filtering Allele Frequency of 8.88% far exceeds the BS1 threshold of 0.00156%, further supporting a benign classification.
NM_000551.3:c.-77C>T is observed in 332 homozygotes in gnomAD v4.1 and 36 homozygotes in gnomAD v2.1, incompatible with autosomal dominant von Hippel-Lindau disease with high penetrance.
ClinVar classifies this variant as Benign (Variation ID 256649; 2 clinical laboratories) and Likely benign (1 clinical laboratory).
No pathogenic or likely pathogenic criteria were met. PM2 was not met (frequency far exceeds PM2_Supporting threshold). PP3 was not met (no computational evidence of deleterious effect). PVS1, PS1, PM1, and PM5 are not applicable to this 5'UTR variant.
Under VHL VCEP v1.1.0 combination rules (Rule 17), BA1 alone is sufficient for a Benign classification. Overall classification: Benign.
