Proceedings of the 12th International Meeting on Neuroacanthocytosis, Cohen Syndrome, and Other VPS13-Related Disorders

The 12^th International Meeting on Neuroacanthocytosis, Cohen Syndrome, and other VPS13-related Disorders was held on September 12^th-14^th, 2025, at the Jules Gonin Eye Hospital in Lausanne, Switzerland. This long-standing series of international symposia has traditionally focused on neuroacanthocytosis syndromes and associated disorders. The program further broadened its scope to include Cohen syndrome, reflecting the growing recognition of shared molecular features and common unsolved questions across VPS13-related disorders. The aim of the meeting was to present the latest updates in the field, from both clinical and basic science perspectives, and to facilitate collaboration and exchange of ideas among researchers, clinicians, and the patient community. An important aspect of these meetings is the active involvement of patients, their relatives and caregivers, who were invited to attend scientific sessions, in addition to participating in parallel patient-oriented sessions. A total of 20 oral communications were presented in eight scientific sessions accompanied by two keynote lectures, short talks by selected poster presenters, and the 2025 "Glenn Irvine Prize" award lecture.
