Abstract
Von Hippel‑Lindau (VHL) syndrome is an autosomal dominant neoplastic disorder. The VHL tumor suppressor (VHL) gene has previously been identified to represent the causative gene of VHL. Previous studies have demonstrated that >506 different mutations in VHL are associated with VHL syndrome. The aim of the present study was to determine the VHL gene mutation present in a VHL syndrome pedigree and to investigate the pathogenesis of the mutant protein. Briefly, a family suffering from VHL syndrome in a Chinese Han population was recruited, and a missense mutation (c.345 C>A: p.H115Q) was revealed to be present within the VHL gene in the proband. Furthermore, Sanger sequencing revealed two carriers of the mutation within the family. The results of the present study also demonstrated a mutation in VHL associated with the VHL syndrome phenotype, which may be of future therapeutic benefit for the diagnosis of VHL syndrome. These results may also be relevant to further studies aiming to investigate the molecular pathogenesis of VHL syndrome.
