Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PVS1_Moderate

This summary comes from the ClinGen Evidence Repository: The variant NM_000551.4(VHL):c.634G>T (p.Gly212Ter) is a nonsense variant that may cause loss of function of the protein, however it is predicted to escape nonsense mediated decay and remove <10% of the protein. It is within 2 amino acids from the last in VHL, and AA 205-213 have unknown or uncertain function in the protein (PVS1_Moderate). The GroupMax Filtering Allele Frequency (95% CI) in gnomAD v4.1.0 is 0.00001063 (3/74922 from African/African American Population). This is lower than the ClinGen VHL VCEP threshold expected for VHL disease, of >=0.0000156 (0.00156%) for BS1, and therefore does not meet any criterion (BS1, BA1, PM2_Supporting are not met). A total of 12 cases are reported from 3 commercial laboratories, and none of the cases harbor VHL spectrum tumors (PS4_NotMet). There are no additional cases reported in published literature. 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). LINK:https://erepo.genome.network/evrepo/ui/classification/CA351756706/MONDO:0008667/078

Genes affected
VHL (HGNC:12687): (von Hippel-Lindau tumor suppressor) This gene encodes a component of a ubiquitination complex. The encoded protein is involved in the ubiquitination and degradation of hypoxia-inducible-factor (HIF), which is a transcription factor that plays a central role in the regulation of gene expression by oxygen. In addition to oxygen-related gene expression, this protein plays a role in many other cellular processes including cilia formation, cytokine signaling, regulation of senescence, and formation of the extracellular matrix. Variants of this gene are associated with von Hippel-Lindau syndrome, pheochromocytoma, erythrocytosis, renal cell carcinoma, and cerebellar hemangioblastoma. [provided by RefSeq, Jun 2022]
