Mutations of the COPA gene cause an immune dysregulatory disease characterised by polyarticular arthritis and progressive interstitial lung disease with pulmonary haemorrhages. We report the case of a young girl that presented at age 3 with polyarticular arthritis, chronic cough and high titer rheumatoid factor. Radiologic imaging showed interstitial lung disease with tree-in-a-bud nodules and air-filled cysts. Targeted genetic analysis of COPA gene showed the reported c.698G>A mutation. The patient was lost to follow up for 3years during which therapy was discontinued with the development of joint damage and deformities. Analysis of peripheral blood showed activation of type 1 interferon pathway, which was also confirmed in 4 previously reported COPA patients. Our observations underline the importance of early treatment in COPA disease to avoid loss of joint function. Furthermore, our results suggest a role for type 1 interferon in disease pathogenesis opening the possibility for targeted therapeutic approaches.
