Recommendations for the diagnosis and management of typical childhood spinal muscular atrophy.

Typical childhood spinal muscular atrophy is a disease that affects the anterior horn of the spinal cord related to SMN1 gene defects. Since no etiological treatment is currently available, its management is necessarily symptomatic and involves multidisciplinary care. The national plan on rare diseases for 2005-2008 developed by the French Ministry of Health resulted in the creation of 12 reference centres for neuromuscular diseases, mainly to improve their diagnosis and management. During the first one-day clinical research meeting on neuromuscular disorders, organized by the French Association to fight myopathies (AFM) in May 2007, clinicians from the 12 national reference centers led workshops for each of the main neuromuscular diseases. Concerning spinal muscular atrophy, discussions involving specialists from medical and allied professions were led by clinicians in charge of the workshop sessions. This paper reports the final version of their recommendation regarding the diagnosis, monitoring and management of typical infantile spinal muscular atrophy, which is necessarily multidisciplinary, including orthopedic, pulmonary, gastroenterology and nutrition care.
