Predictive, Oncogenic, Functional evidence:
Oncogenic: The abstract states that Acvr1G328V cooperates with other mutations to induce diffuse gliomas in mice, indicating that this variant contributes to tumor development. This aligns with the definition of an oncogenic variant, as it demonstrates a role in the progression of cancer.
Functional: The abstract mentions that Acvr1G328V upregulates transcription factors to block oligodendroglial cell differentiation, suggesting that this variant alters molecular function. This indicates a change in biochemical activity related to cell differentiation processes.
Predictive: The abstract notes that E6201, a covalent MEK1/2 inhibitor, can inhibit ACVR1 and reduce the growth of ACVR1 mutant glioma xenografts, implying that the presence of the G328V variant may correlate with response to this specific therapy. This suggests a predictive relationship between the variant and treatment response.
