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.292T>A(p.Tyr98Asn) 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. Y98H) 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 hotspot region, there are 10 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 2 benign, 14 uncertain 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 chr3-10142139-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 2223.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.974
• PP5: Variant 3-10142139-T-A is Pathogenic according to our data. Variant chr3-10142139-T-A is described in ClinVar as [Pathogenic]. Clinvar id is 2627292.Status of the report is criteria_provided_single_submitter, 1 stars.

Variant summary: VHL c.292T>A (p.Tyr98Asn) results in a non-conservative amino acid change located in the von Hippel-Lindau disease tumour suppressor, beta/alpha domain (IPR022772) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 223372 control chromosomes (gnomAD). c.292T>A has been reported in the literature in multiple individuals affected with Von Hippel-Lindau Syndrome (examples: Liu_2018, Krzystolik_2016). Other variants affecting the same residue (p.Tyr98His, p.Tyr98Cys) have been classifed pathogenic internally and in ClinVar (CV IDs: 2223, 223176). These data indicate that the variant is very likely to be associated with disease. The following publications have been ascertained in the context of this evaluation (PMID: 29595810, 26308528). No submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as pathogenic. -
