Variant summary

Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM1 PM2 PM5 PP3_Strong PP5_Moderate

The NM_000551.4(VHL):​c.193T>A​(p.Ser65Thr) variant causes a missense change. 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 Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S65L) has been classified as Pathogenic.

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]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PM1: In a chain von Hippel-Lindau disease tumor suppressor (size 212) in uniprot entity VHL_HUMAN there are 96 pathogenic changes around while only 8 benign (92%) in NM_000551.4
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr3-10142041-C-T is described in Lovd as [Pathogenic].
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.966
• PP5: Variant 3-10142040-T-A is Pathogenic according to our data. Variant chr3-10142040-T-A is described in ClinVar as [Pathogenic]. Clinvar id is 1426858.Status of the report is criteria_provided_single_submitter, 1 stars.

This variant disrupts the p.Ser65 amino acid residue in VHL. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 7728151, 7987306, 10567493). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. This sequence change replaces serine with threonine at codon 65 of the VHL protein (p.Ser65Thr). The serine residue is highly conserved and there is a small physicochemical difference between serine and threonine. This variant is not present in population databases (ExAC no frequency). This missense change has been observed in individual(s) with clinical features of von Hippel-Lindau syndrome (PMID: 32420132; Invitae). In at least one individual the variant was observed to be de novo. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt VHL protein function. For these reasons, this variant has been classified as Pathogenic. -
