Patients with ELSTs were identified and included in the International Endolymphatic Sac Tumor Registry. The registry contained 93 patients as of July 2014, and of those, 25 were sporadic, and 68 associated with VHL. Patients with ELSTs and clinically confirmed diagnoses of VHL were included in this study. Statistics of this VHL subgroup are as follows: mean age 30, 62% female, 91% symptomatic, 54% with retinal angioma, 72% with CNS hemangioblastoma, 46% with renal cell carcinoma, 19% with pheochromocytoma, and 12% with pancreatic neuroendocrine tumour. In the data from this study, only endolymphatic sac tumours can be confirmed as a phenotype for this mutation (c.339delA), which was found in 1 individual from Germany.
