|Official Title ICMJE||SMN Copy Number Distribution in Mali, West Africa|
- To collect blood samples for use in studying genetic data related to spinal muscular atrophy.
-< TAB> Bamako, Mali, West Africa
Spinal muscular atrophy (SMA) is an autosomal recessive motor neuron disease that is caused by mutations in the survival motor neuron gene, SMN1. The objective of this study is to determine the SMN copy number distribution in the Malian population and to compare this to published data obtained elsewhere. It is anticipated that this study will help to refine the knowledge of SMA by assessing the distribution of SMN copy number, and the SMA carrier frequency in a sub-Saharan nation, thus expanding the information base available to clinicians and patients considering SMA carrier testing.
The study population will include 1400 adult (18 years of age and older) volunteers only.
Blood samples from volunteers will be collected from students at the School of Medicine, Pharmacy, and Dentistry (FMPOS) at the University of Bamako, which consists of an ethnically diverse population representative of the Malian ethnicities. No therapy will be provided to study participants.
Outcome measure for phase 1 is DNA extraction yield of sufficient quantity and quality for SMN genotyping by LabCorp in at least 90% of samples. Outcome measures for phase 2 are the frequency of SMA carriers (SMN1 deletion heterozygotes) and the SMN1 and SMN2 copy number distribution in Mali.
