Alström syndrome (AöS) is a rare genetic disorder characterized by metabolic problems. Here, the authors show that in AöS models, defects in cilia and autophagy lead to ACBP accumulation, which drives obesity. An anti-ACBP antibody reduces weight gain and metabolic dysfunction, highlighting ACBP as a therapeutic target for this ciliopathy.
