Abstract
Von Hippel-Lindau (VHL) disease is a hereditary tumor syndrome in which carriers are at an increased risk of developing a variety of tumors in multiple organ systems. A clinical diagnosis of VHL is determined by the presence of specific clinical manifestations while a molecular genetic diagnosis results from a pathogenic variant in the VHL gene. The majority of mutations occur in VHL coding exons and DNA analysis of these regions has a reported sensitivity of nearly 100%. However, rare variants in the VHL gene promoter may be detected in some cases of suspected VHL disease. We report two cases where VHL promoter variants were detected and describe the role of multi-step mRNA and protein analysis in the diagnostic evaluation of these cases.
