PW03-016 – Blau prospective cohort study: articular outcomes

Blau syndrome is an autosomal dominant monogenic granulomatous disease associated with gain of function mutations at or near the NACHT domain of NOD2; it is the only form of granulomatous arthritis with a known gene mutation. Although its phenotype has been amply described as a triad of arthritis, uveitis and dermatitis in case series and retrospective cohorts, prospective studies on natural history and outcome have not been done.
