Establishing resources and increasing awareness to advance research on Dentatorubral-pallidoluysian atrophy toward a treatment: a patient organization perspective.

Dentatorubral-pallidoluysian atrophy (DRPLA) is an ultra-rare neurodegenerative disorder characterized by ataxia, cognitive decline, myoclonus, chorea, epilepsy, and psychiatric manifestations. This article delves into the multifaceted efforts of CureDRPLA, a family-driven non-profit organization, in advancing research, raising awareness, and developing therapeutic strategies for this complex condition. CureDRPLA's inception in 2019 led to the establishment of the DRPLA Research Program, and since then have funded research projects to advance the understanding of DRPLA including but not limited to human cellular and mouse models, a natural history and biomarkers study, and a patient registry. There are currently no disease-modifying treatments for DRPLA, motivating a concerted effort on behalf of CureDRPLA to hasten their development by funding and coordinating preclinical studies of therapies in multiple modalities. Of particular interest are therapies focused on lowering the expression (or downregulation) of ATN1, the mutant gene that causes DRPLA, in hopes of tackling the pathology at its root. As with many ultra-rare diseases, a key challenge in DRPLA remains the complexity of coordinating both basic and clinical research efforts across multiple sites around the world. Finally, despite the generous financial support provided by CureDRPLA, more funding and collective efforts are still required to advance research toward the clinic and develop effective treatments for individuals with DRPLA.
