Brief Summary:

The study aims to elucidate hypoxia-induced angiogenesis in tumor development using central nervous system (CNS) hemangioblastoma tumorgenesis as a model.

In a pilot-project the investigators will identify genetic drivers of CNS hemangioblastoma progression and associated cyst development using whole genome sequencing and copy number profiling of tumor DNA paired with clinical information about each tumor's growth pattern. The investigators will look for recurrent mutations across tumors to identify common genetic mechanisms involved in early tumorigenesis.
