Evidence Type(s): Oncogenic, Predisposing

Justification: Oncogenic: The text indicates that 90% of the cases harbored the IDH1-R132H mutation, which is associated with conventional supratentorial IDH-mutant astrocytomas, suggesting its role in tumorigenesis. Predisposing: The mention of a personal and family history of colorectal cancer in case no. 10, along with the identification of germline mutations in MMR genes, suggests a predisposition to cancer in these cases.

Gene→Variant (gene-first): IDH1(3417):R132H

Genes: IDH1(3417)

Variants: R132H

Evidence Type(s): Diagnostic, Oncogenic

Justification: Diagnostic: The passage indicates that 90% of the cases harbored IDH1-R132H mutations, which are associated with conventional supratentorial IDH-mutant astrocytomas, suggesting a role in defining or classifying the disease. Oncogenic: The presence of IDH1-R132H mutations in the tumors suggests that this somatic variant contributes to tumor development or progression, as it is commonly found in a specific type of cancer.
