study description: As secondary objectives, the study aims:
to estimate the frequencies of patients with SMA 5q types 1 through 4 who have being treated in the reference centers between September 1 2016 and August 31 2024;
to describe overall demographic, familial, clinical, biological, and genetic characteristics of SMA 5q patients treated in all regions of France, by the type of SMA (type 1,2,3, and 4);
to study the impact of proactive and symptomatic medical interventions (bracing, IPPB devices) and medications (vaccinations, anti-infectious, digestive, nutritional supplements) in the evolution of patients;
to study the long-term evolution (survival, motor and respiratory functions, spinal shape, growth and nutritional function) of SMA 5q in treated and untreated populations, by new available therapies, throughout the register;
to study mortality rate of SMA 5q in treated and untreated populations, by new available therapies, throughout the register;
to identify and document the different therapeutic strategies by sub-populations and by discontinuation or follow-up of treatments;
to evaluate prognostic factors of responses to therapies;
to study the tolerance of treatments by type of treatments, by type of SMA and overall tolerance (including adverse events);
to estimate the costs of care for SMA 5q patients in different groups (types, ages);
to provide needful elements to evaluate the health care costs for the disease;
to study the autonomy and the quality of life of patients depending on different therapeutic strategies;
to study the impact of the disease on caregivers;
to facilitate development of scientific research on SMA in the conduct of trials on new therapeutic strategies.
primary outcomes:
- Motor functional development or status
SMA Type 1 until 2 years of age: change of HINE (Hammersmith Infant Neurological Examination) score
Children: change in Vignos and Brooke scores (level of upper and Lower extremities autonomy)

For children children > 6 years and adults, ambulatory or not: Change of total MFM-32 (Motor Function Measure 32) score will be evaluated. Change of 3 dimension scores will be evaluated: D1 (start and transfers station), D2 (axial and proximal motricity) and D3 (distal including the upper limb).
For ambulatory individuals: added 6MWT (6 minutes walking test)
