Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PVS1PM2
The NM_000551.4(VHL):c.46G>T(p.Glu16Ter) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. E16E) has been classified as Likely benign.

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]

Von Hippel-Lindau syndrome;C1837915:Chuvash polycythemia Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 24, 2023 | This sequence change creates a premature translational stop signal (p.Glu16*) in the VHL gene. It is unclear whether it will result in an absent or disrupted protein product because an in-frame methionine located at codon 54 has the potential to rescue this variant. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with VHL-related conditions. ClinVar contains an entry for this variant (Variation ID: 456590). RNA analysis performed to evaluate the impact of this premature translational stop signal on mRNA splicing indicates it does not significantly alter splicing (Invitae). Several studies have shown that the VHL protein created from a downstream methionine located at codon 54 is biologically active, and exhibits properties similar to the full-length, wild-type protein (PMID: 9671762, 9751722). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 04, 2024 | The p.E16* variant (also known as c.46G>T), located in coding exon 1 of the VHL gene, results from a G to T substitution at nucleotide position 46. This changes the amino acid from a glutamic acid to a stop codon within coding exon 1. Premature stop codons are typically deleterious in nature; however, an alternate initiation codon exists 38 residues downstream from this alteration and is reported to result in a biologically active isoform known as VHL19 (Iliopoulos O et al. Proc. Natl. Acad. Sci. U.S.A. 1998 Sep;95(20):11661-6; Schoenfeld A et al. Proc. Natl. Acad. Sci. U.S. A. 1998 Jul;95(15)8817-22). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
