The targeted somatic sequencing of GCT-related genes (H3F3A, H3F3B, IDH1, IDH2 and ZNF687) was performed on Clival GCT biopsies of two different cases.
As the relationship between GCT-ST and GCT-B is unclear, the aim of this study was to compare a series of GCT-STs and GCT-Bs with regard to the presence of H3F3A mutations and several immunophenotypic markers.
