New Lab Model Could Shed Light on Mitochondrial Epilepsy and Therapies

Researchers have created the first laboratory model of epilepsy caused by mitochondrial disorders with the potential to improve scientists’ understanding of how this condition unfolds and to develop therapies to combat it. Until now, no animal models were available to study this severe form of epilepsy, but this new…

New Mutations Found in Mitochondrial DNA That Cause LHON, Study Finds

Researchers have found that certain mutations in the mitochondrial genes, which alone don’t seem to cause disease, are sufficient to trigger Leber’s hereditary optic neuropathy (LHON) when combined. Based on their findings, researchers defend a new approach for diagnosing LHON and perhaps other mitochondrial…
