Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Autoimmune necrotizing myopathies (AINM) in adult patients are characterized by severity of muscle damage, presence of necrosis with little inflammation on muscle biopsy and anti-HMGCR or anti-SRP auto-antibodies. Data on AINM in children are currently lacking. The purpose of this study is to specify the characteristics at AINM diagnosis, treatments and evolution of juvenile AINM with anti-HMGCR or anti-SRP antibodies.
