VHL VCEP
The NM_000551.4(VHL):c.500G>A (p.Arg167Gln) variant in VHL is a missense variant predicted to cause substitution of arginine by glutamine at amino acid 167. This missense mutation has been identified in at least 19 unrelated individuals with von Hippel-Lindau disease. Mostly VHL Type 2 or 2B phenotypes are noted. However, some publications describe VHL Type 1 as well. PMIDs used: 20846682, 8707293, 9829912, 9829911, 7728151, 12114495, 12624160, 14722919. CIViC EIDs used (https://civicdb.org): 5485, 5354, 5264, 5062, 4913, 5487, 5546, 6118. 2 participating commercial laboratories reported >7 and >20 cases. The number of proband and/or family cases fulfills the criteria for strong evidence (PS4). Multiple publications (PMID: 15574766, PMID: 19030229) support disruption of Elongin C binding with the Arg167Gln variant, as well as altered regulation of HIF2a and near wild type regulation via ubiquitination of HIF1a (PS3_Supporting). A de novo (and mosaic ~5.5% allele freq in blood and ~34% in a pheochromocytoma at ~80% tumor purity) case was identified in a 16yo with no family history of VHL and fulfilling Danish Criteria for VHL (The 16yo had the following: Hb, pheochromocytoma, pancreatic endocrine tumor, left adrenal nodule). PMID: 30731206, CIViC evidence ID: EID7714. 1 commercial laboratory reports a de novo case in a child with bilateral retinal hemangiomas in the age range of 10yo (PM6). This variant is absent from gnomAD v4.1.0 (PM2_Supporting). Arg167 is one of the germline hotspots outlined by the VHL VCEP, and it is in the Elongin binding domain (PM1). The computational predictor REVEL gives a score of 0.874, which is above the threshold of >=0.664, evidence that correlates with impact to VHL function (PP3). Per VHL VCEP specifications, this code is applied when the REVEL score is >=0.6. (PP3). In summary, this variant meets the criteria to be classified as Pathogenic 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).

PS3_Supporting
Multiple publications support disruption of Elongin C binding with the Arg167Gln variant, as well as altered regulation of HIF2a and near wild type regulation via ubiquitination of HIF1a.
Rathmell et al results display R167Q has impaired regulation of HIF2a, normal regulation of HIF1a, and impaired binding to Elongin C. PubMed:15574766
Hacker et al shows R167Q confers partial suppression of HIF2a , inability to bind Elongin C and retains the ability to ubiquitinate HIF1a, similar to WT VHL. PubMed:19030229
