The variant NM_000551.3(VHL):c.341-2A>G is a canonical splice site within the 1st intron of the VHL gene, and is predicted to undergo nonsense mediated decay (PVS1). This variant is absent from gnomAD v4.1.0 (PM2_Supporting). This variant has been reported in at least 3 studies, in cases or families with VHL syndrome or VHL-related cancers. PMIDs: 17661816, 17024664, 27539324, CIViC EIDs (https://civicdb.org): 5748, 5730. Two commercial laboratories report 1 case each, both with a history of VHL-related cancers. One had an additional clinical diagnosis of VHL and a first degree relative with multiple VHL-related cancers in age 30-40yrs who was also VHL positive (PS4_Moderate). Although PP3 was not applied due to use of PVS1, we include the note that multiple splice predictors were used to evaluate the splice site. VarSeak supports the impact of disrupting this canonical splice site (Class 5) and the Splice AI score is 0.93, indicating impact on splicing. 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).
