Evaluation of a New Sequencing Strategy in Autoinflammatory Siseases (BIOSAID)

Main objective: To compare the efficacy of a new strategy of Next Generation Sequencing (NGS) versus a classical Sanger strategy, for the diagnosis of patients referred to the laboratory for suspected systemic autoinflammatory diseases (SAID). Secondary objectives: * Compare after 6 months the impact of these strategies on the establishment of an effective treatment SAID following genetic result. * Compare the distribution of different forms of SAID found with each genetic diagnostic strategies (NGS vs classic method).
