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 Uncertain_significance. Variant got 4 ACMG points.

• PM1: In a hotspot region, there are 10 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 14 uncertain in NM_000551.4
• PM4: Nonframeshift variant in NON repetitive region in NM_000551.4. Strenght limited to Supporting due to length of the change: 1aa.
• PP5: Variant 3-10142067-GTCA-G is Pathogenic according to our data. Variant chr3-10142067-GTCA-G is described in ClinVar as [Pathogenic]. Clinvar id is 2214.Status of the report is no_assertion_criteria_provided, 0 stars.
