Hemangioblastomas of Central Nervous System: Molecular Genetic Analysis and Clinical Management

Abstract

Molecular genetic analysis is a safer and more specific instrument to confirm or exclude VHL disease in patients with CNS hemangioblastoma, a negative family history, or absence of other known manifestations of the disease. Early identification of VHL mutation gene carriers is important for reducing disease morbidity and mortality. Nonsymptomatic family members will benefit from early VHL disease diagnosis or by being excluded as at-risk subjects, reducing the psychological and economic burden of screening and surveillance protocols.
