This study aims to better understand the m.3243 A>G mitochondrial DNA mutation, which can cause symptoms like migraines, seizures, and hearing loss. It's a "Natural History Study," meaning researchers will observe how the condition changes over time without giving any new treatments. The goal is to learn more about the problems patients face and help develop future treatments. You might be able to join if you or a maternal relative carry the m.3243 A>G mutation. Paternal relatives will also be included as a comparison group. The study will look at how this mutation affects your brain and body, even if the symptoms are mild. Success for this study means gaining a clearer picture of how the mutation impacts people over 2-3 years, as measured by brain scans (MRI/MRS). The study is currently unclear on its recruitment status and plans to enroll 300 participants.

Study design
