Oncogenic, Functional evidence:
Oncogenic: The abstract indicates that the p.Lys27Met substitution in histone H3 variants is associated with pediatric midline high-grade astrocytomas (mHGAs), suggesting that this somatic variant contributes to tumor development or progression. The mention of specific mutations and their association with tumor location further supports the oncogenic role of this variant in the context of these tumors.
Functional: The study discusses how the p.Lys27Met alteration is linked to hyperactivation of the BMP-ACVR1 pathway and increased levels of phosphorylated SMAD proteins, indicating that this variant alters molecular or biochemical function within the tumor cells. This suggests a functional impact of the variant on the signaling pathways involved in tumor biology.
