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]

The p.L178R pathogenic mutation (also known as c.533T>G), located in coding exon 3 of the VHL gene, results from a T to G substitution at nucleotide position 533. The leucine at codon 178 is replaced by arginine, an amino acid with dissimilar properties. This alteration has been observed in multiple patients with personal and/or family history consistent with Von Hippel-Lindau syndrome (VHL) (Webster AR et al. Arch Ophthalmol, 1999 Mar;117:371-8; Ong KR et al. Hum Mutat, 2007 Feb;28:143-9; Wu P et al. J Hum Genet, 2012 Apr;57:238-43; Sriphrapradang C et al. Clin Med Insights Endocrinol Diabetes, 2017 Apr;10:1179551417705122). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -
