Eligibility

INCLUSION CRITERIA

• Males or females of any ethnic group

• ß-SG deoxyribonucleic acid (DNA) gene mutations at both alleles

• Weakness demonstrated based on history of difficulty in running, jumping and climbing stairs

• A 100 meter walk/run (MWR) test result: =40 % of predicted for age-, height-, gender-, and weight-matched healthy controls at the screening visit

EXCLUSION CRITERIA

• Active viral infection based on clinical observations

• Cardiac magnetic resonance imaging (MRI) determined left ventricular ejection fraction (LVEF) <40%
