Germline mutations in the von Hippel–Lindau gene in Italian patients

von Hippel–Lindau syndrome (VHL) is a dominantly inherited familial cancer syndrome predisposing to a variety of malignant and benign tumours, most frequently retinal, cerebellar, and spinal hemangioblastoma, renal cell carcinoma, pheochromocytoma, and pancreatic tumours.The current study investigated the occurrence of VHL mutations in Italian patients with classic VHL disease or with atypical VHL-like clinical features referred to the Service of Medical Genetics for VHL molecular diagnosis. In addition, an RQ-PCR protocol was validated in order to introduce it in the routine VHL laboratory diagnosis.
