Somatic Histone H3 Alterations in Paediatric Diffuse Intrinsic Pontine Gliomas and Non-Brainstem Glioblastomas

To identify somatic mutations in paediatric diffuse intrinsic pontine gliomas (DIPGs), we performed whole genome sequencing of 7 DIPGs and matched germline DNA, and targeted sequencing of an additional 43 DIPGs and 36 non-brainstem paediatric glioblastomas (non-BS-PGs). 78% of DIPGs and 22% of non-B...

Sumario:To identify somatic mutations in paediatric diffuse intrinsic pontine gliomas (DIPGs), we performed whole genome sequencing of 7 DIPGs and matched germline DNA, and targeted sequencing of an additional 43 DIPGs and 36 non-brainstem paediatric glioblastomas (non-BS-PGs). 78% of DIPGs and 22% of non-BS-PGs contained p.K27M mutation in H3F3A, encoding histone H3.3, or the related HIST1H3B, encoding histone H3.1. An additional 14% of non-BS-PGs had somatic p.G34R H3F3A mutations.
