NCT03300869

Brief Summary

The primary objective of this study is to investigate the natural history of spinal muscular atrophy (SMA) types 2 and 3 patients in Taiwan. This study will provide further insights into the clinical course SMA. Several analyses will be conducted regarding overall survival, demographic characteristics, motor function, respiratory and nutritional support, and genotype and phenotype correlation.

Outcome Measures

Primary Outcomes (1)

  • Describe the correlation of genotype and phenotype in SMA types 2 and 3

    Genotype is defined by SMN 2 copy number(s) and phenotype is defined by clinical types and characteristics.

    through study completion, an average of 2 years

Secondary Outcomes (4)

  • Disease onset in patients with SMA types 2 and 3

    through study completion, an average of 2 years

  • Disease mortality in patients with SMA types 2 and 3

    through study completion, an average of 2 years

  • Scoliosis in patients with SMA types 2 and 3

    through study completion, an average of 2 years

  • BiPAP usage in patients with SMA types 2 and 3

    through study completion, an average of 2 years

Sampling MethodNon-Probability Sample
Study Population

In the past decades, The SMA is a rare disease (incidence of 1 in every 6,000-10,000 live births) with a carrier frequency of about 1 in 40-50 people. Therefore, individual countries have small cohorts of affected patients.

You may qualify if:

  • Patients are diagnosed with SMA types 2 or 3
  • Generalized hypotonia and muscle weakness, weakness of the legs is greater than the arms, and the proximal part is weaker than distal part of extremities.
  • SMN1 gene deletion or mutation and/or neurogenic changes in electromyogram and/or muscle pathology.

You may not qualify if:

  • Non-5q SMA (no deletion or mutation of SMN1 gene) patients.
  • Type 1 SMA patients.
