Understanding IDH1 Mutation in Astrocytoma
Astrocytomas are a type of glioma that have genetic factors, like IDH1 mutations. It’s key to know how IDH1 mutations affect astrocytoma growth and spread.
Genetic Basis of IDH1 Mutation
The IDH1 mutation changes the IDH1 enzyme, which is important for brain cells. These changes make an oncometabolite called 2-hydroxyglutarate. This oncometabolite messes with normal cell processes.
It can also affect other genes and markers in astrocytoma, helping tumors grow.
Prevalence in Astrocytoma Patients
Studies show IDH1 mutations are common in many astrocytoma patients. They are most common in low-grade gliomas and in young patients. Knowing this helps doctors plan treatments better.
| Grade | Prevalence of IDH1 Mutation (%) |
|---|---|
| Low-Grade Glioma | 70-80% |
