Our community’s most beloved Liocorn design, Roar For Rare celebrates the strength and unity of every family affected by CASK gene disorders.

The back features the first names and countries of CASKies worldwide, as part of the Project CASK Liocorn Roster, the most comprehensive global count of people with CASK gene disorders to date.

Parents can request to have their loved one’s name included by registering here: https://www.tfaforms.com/5104302

The roster is updated quarterly to honor our growing global network of CASK families and advocates.
