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]

Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 23, 2016 | The c.163delG pathogenic mutation, located in coding exon 1 of the VHL gene, results from a deletion of one nucleotide at nucleotide position 163, causing a translational frameshift with a predicted alternate stop codon. This mutation, designated as 376delG, has been reported in an individual with clinical features of von Hippel-Lindau syndrome (VHL) (Chen F et al. Hum. Mutat., 1995;5:66-75). Additionally, mRNA studies in Drosophila strains with this mutation confirmed that this frameshift alteration triggers nonsense-mediated decay (Micale L et al. J. Biomed. Biotechnol., 2009 Jan;2009:860761). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. - |
