Summary

Background:

* Spinal muscular atrophy (SMA) is a degenerative and incurable neuromuscular disorder that is caused by mutations in the survival motor neuron gene, SMN1, found on chromosome 5. It is the leading inherited cause of infant mortality. SMA carriers (those who have the genetic mutation but do not have the disease) are often unaware of their status until they are tested.
* Researchers have been studying the prevalence of SMA carriers in the general population, but most of the information collected has come from populations within the United States, Europe, and Asia. Very few studies have been performed in Africa. Furthermore, this information does not provide much information regarding carrier frequency based on ethnic background and ancestry. To address this problem, researchers are interested in studying the prevalence of the SMA genetic mutation in the sub-Saharan nation of Mali.

Objectives:

\- To collect blood samples for use in studying genetic data related to spinal muscular atrophy.

Eligibility:

* Healthy volunteers who are at least 18 years of age.
* Volunteers will be of Malian ancestry and nationality.

Study Location:

-\<TAB\>Bamako, Mali, West Africa

Design:

* The study will first collect blood samples from a small group of volunteers to run initial SMA carrier testing and resolve any technical difficulties before continuing with the study.
* Participants will complete questionnaires about their personal and family medical history, including questions about illnesses, stillborns, and miscarriages, and then will provide blood samples for genetic research and testing.
