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 Likely_benign. Variant got -5 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.69).

Submissions by phenotype

not specified Benign:2

Likely benign, criteria provided, single submitter	clinical testing	GeneDx	Jul 27, 2017	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

This variant occurs in a non-coding region of the VHL gene. It does not change the encoded amino acid sequence of the VHL protein. This variant is present in population databases (rs745439844, gnomAD 0.02%). 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: 511159). 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. -
