Human Monocytic Models Reveal Genotype‐Dependent Inflammatory Programs in VEXAS Syndrome

Arthritis &Rheumatology, Accepted Article.
Objectives VEXAS syndrome is a severe X‐linked autoinflammatory disorder caused by somatic mutations in ubiquitin‐like modifier activating enzyme 1 (UBA1), with clinical outcomes that vary by UBA1 genotype. We aimed to elucidate genotype‐specific inflammatory programs and identify potential therapeutic targets.
