Our lab focuses on the genetic and genomic basis of epilepsy disorders, including analyses of the role of germline mutations, somatic mutations, and how regulation of the cellular transcriptome influences the risk and presentation of seizures.
In collaboration with a number of investigators in neurology, neuropathology, and neurosurgery, a major focus of the group is the study of the role of somatic mutations in epilepsy and other neurological diseases. Unlike inherited variation or newly acquired mutations in parental gametes that present in the germline of offspring, mutations can also be acquired somatically at some point in development after fertilization. The burden and localization of a somatically-acquired mutation depends on when each mutation arises. Like inherited genetic variation, there is accumulating evidence that new mutations can lead to disease, and in some cases, severe tissue-specific disease. Furthermore, recent studies have identified a surprising degree of mosaicism in healthy human neurons. The lab currently has active research projects seeking to identify and molecular characterize disease-causing somatic mutations in patients with brain malformations and in patients who have drug-resistant non-lesional focal epilepsies.
We also focus on the study of the transcriptome in brain tissue of epilepsy patients to better understand how regulation at this level may cause or contribute to the presentation of epilepsy. Making use of therapeutically-excised tissue specimens from patients with a range of refractory epilepsies, we use a variety of experimental approaches to study the tissue and cellular transcriptome and relate transcriptional changes to pathological endpoints. Relevant changes are then studied in depth using a range of in vitro and in vivo models to determine how the associated transcriptional changes contribute to disease pathophysiology.
