Single nucleotide variation in C13orf31 encoding p.C284R and p.I254V in a protein of unknown function causes systemic juvenile idiopathic arthritis, and associates with risk for leprosy and Crohn’s disease, respectively. Here we set out to uncover the underlying mechanism. C13orf31 formed a complex with fatty acid synthase on peroxisomes and promoted flux through de novo lipogenesis to concomitantly drive high levels of fatty acid oxidation (FAO) and glycolysis, and consequently ATP regeneration. C13orf31-dependent FAO controlled inflammasome activation, mitochondrial and NADPH oxidase-dependent reactive oxygen species production, and bactericidal activity of macrophages. With p.I254V and p.C284R exhibiting decreased and loss of function, respectively, C13orf31 determined organismal resilience to endotoxin shock. We hence discovered a central regulator of macrophage metabolic function and bioenergetic state, which is under evolutionary selection and determines risk for inflammatory and infectious disease.
