Jeffrey MacKeigan, PhD



Jeff MacKeigan, Professor in the College of Human Medicine’s Department of Pediatrics and Human Development, studies the mTOR pathway, which plays an important role in cancer and tuberous sclerosis complex (TSC). TSC is a rare tumor syndrome that is usually diagnosed during childhood, and causes tumors to form in the heart, brain, skin, kidneys, and lungs. Children with TSC may suffer from infantile spasms and epilepsy, along with cognitive disorders and developmental delays. Dr. MacKeigan’s lab has characterized the genomic landscape of TSC and is working with clinical collaborators to translate this knowledge into new discoveries for patients.
