Variant summary
Our verdict is Uncertain significance. The variant received -4 ACMG points: 4P and 8B. BS1PM1PS3_SupportingPP3BS2
This summary comes from the ClinGen Evidence Repository: The variant NM_000551.4(VHL):c.562C>G (p.Leu188Val) is a missense variant predicted to cause substitution of Valine for Leucine at position 188. The GroupMax Filtering Allele Frequency (95% CI) in gnomAD v4.1.0 is 0.00002474 (39/1180038 from European, Non-Finnish Population). This is higher than the ClinGen VHL VCEP threshold of >=0.0000156 (0.00156%) threshold expected for VHL disease (BS1). From pooled laboratory data: 105 probands carried this variant, and none met Danish criteria for VHL. 18/105 had a single VHL feature. 27 known carriers were 60+ years old and did not have VHL phenotypes. At least 11 of those 60+ without VHL features had no VHL features reported in the family history (BS2), while 8 had VHL features reported in family history (including a carrier relative who met diagnostic VHL criteria). In most functional studies reviewed, results for this variant were consistent with aberrant extra cellular matrix formation / fibronectin assembly (PMIDs: 19602254, 16452184, 17700531, 15574766, 16585181, 11331612, 18567581). However, for HIF1/2 alpha interaction/regulation and VCB complex formation/stability, most studies showed intact function with some slight effects on complex stability. (PMIDs: 30890701 ,15574766, 12944410, 10878807, 16585181, 19030229, 11331612, 11331613, 19228690, 16452184, 23772956, 19602254.) (PS3_Supporting). The L188V variant is located within the alpha domain (156-192), a key functional domain of VHL (PM1). The computational predictor REVEL gives a score of 0.796, which is above the threshold of >=0.664, evidence that correlates with impact to VHL function (PP3). In summary, this variant meets the criteria to be classified as Uncertain for autosomal-dominant von Hippel Lindau syndrome (VHL syndrome) 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). Note: This variant has been reported as a putative low penetrance VHL type 2C variant; however at this time, the VHL VCEP does not have low-penetrance specific classification recommendations (see ClinGen Low Penetrance / Risk Allele Working Group).
