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 c.-75_-55del variant in VHL has been identified by our laboratory in 1 Cauca sian adult with VHL and segregated with disease in at least 5 affected relatives including 1 obligate carrier. This variant is located in the 5' untranslated re gion (UTR), a regulatory region, and may have an effect on translational efficie ncy. The deleted sequence in this variant is highly conserved in evolutionarily distant species and in vitro studies have shown that a deletion of this region r emoves a transcription factor binding site which is predicted to alter VHL trans cription (Zatyka 2002). In summary, although additional studies are required to fully establish its clinical significance, the c.-75_-55del variant is likely pa thogenic. -
