Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PS3 PM1 PM2 PM4_Supporting PP5_Moderate

The NM_000551.4(VHL):​c.263_265dupGGC​(p.Trp88_Leu89insArg) variant causes a disruptive inframe insertion change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely pathogenic (★). ClinVar reports functional evidence for this variant: "SCV000580983: In addition, based on internal structural assessment, this alteration results in local structural perturbation of the VHL protein fold, near the HIF1&alpha" and additional evidence is available in ClinVar. Synonymous variant affecting the same amino acid position (i.e. L89L) has been classified as Likely benign. The gene VHL is included in the ClinGen Criteria Specification Registry.

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

Specifications for VHL are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PS3: PS3 evidence extracted from ClinVar submissions: SCV000580983: In addition, based on internal structural assessment, this alteration results in local structural perturbation of the VHL protein fold, near the HIF1α-peptide-binding site (Min JH et al. Science, 2002 Jun;296:1886-9; Van Molle I et al. Chem. Biol., 2012 Oct;19:1300-12).
• PM1: In a hotspot region, there are 26 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 5 benign, 36 uncertain in NM_000551.4
• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_000551.4. Strenght limited to Supporting due to length of the change: 1aa.
• PP5: Variant 3-10142109-T-TGGC is Pathogenic according to our data. Variant chr3-10142109-T-TGGC is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 428805.Status of the report is criteria_provided_single_submitter, 1 stars.
