Juvenile idiopathic arthritis (JIA) is a complex and poorly understood condition thought to have genetic influences, characterized by a variety of arthritis types with an unknown origin.
*The study focused on 43 patients with LACC1-associated juvenile arthritis, identifying genetic variants and providing clinical details, including a high prevalence of early onset disease and aggressive treatment responses.
*Results showed that a significant portion of patients exhibited severe forms of arthritis and poor treatment outcomes, expanding the understanding of LACC1's role in JIA pathology.
