TESS Research Foundation is a 501(c)(3) tax exempt public charity. Our mission is to help families affected by SLC13A5 Deficiency. SLC13A5 Deficiency (aka Citrate Transporter Disorder) is a newly discovered genetic cause of epilepsy, and as such, TESS Research Foundation is building a patient-centered network from the ground up. We are determined to diagnose, treat, and ultimately cure SLC13A5 Deficiency. We do this by funding cutting-edge research and connecting families, doctors, and researchers.
