Amyotrophic lateral sclerosis (ALS)-associated genes provide direct therapeutic targets and reveal pathways that can be used to develop treatments that counteract their harmful molecular effects. Because the underlying causes of most ALS cases remain unknown, identifying disease-associated variants is essential to uncover the mechanisms that drive the disease, as shown at the European Network to Cure ALS (ENCALS) meeting, held in Madrid from June 24 to 26, 2026.
