The 7th ATP1A3 in disease symposia will take place at the Feinberg School of Medicine, Chicago, Illinois USA on October 13th and 14th (Saturday to Sunday) 2018. Organising Committee: Allison Brashear, MD (Wake Forest Medical Center), Al George, MD (Northwestern University Medical Center), Kevin Ess, MD, PhD (Vanderbilt University Medical Center), and the AHC Foundation. The 1st Symposium on ATP1A3 in Disease was held in Brussels, Belgium in December 2012, when it was first discovered that alternating hemiplegia of childhood (AHC) was caused by ATP1A3 mutations. Since then the symposiums have been held in Europe and the US. We hope that doctors and researchers who are interested in this field and many family members will attend the symposium. We invite experts on Na+/K+-ATPase and ATP1A3-related diseases from all over the world. We welcome many attendants who are interested in Na+/K+-ATPase and ATP1A3-related diseases. We hope that all attendants will enjoy this symposium and the pleasant autumn season of Chicago. Please register for the symposium here!
