Abstract/OtherAbstract:
BACKGROUND: The C826A mutation in the fukutin-related protein (FKRP) gene is typically associated with autosomal recessive limb-girdle muscular dystrophy 2I (LGMD2I) but oligosymptomatic phenotypes and patients with predominant cardiac involvement are also described. OBJECTIVE: To assess cardiac involvement in patients with LGMD2I. PATIENTS: Nine patients from 5 families (2 female, 7 male) homozygous for the 826C > A FKRP mutation were included. METHODS: Additional to conventional cardiac investigations (electrocardiography and echocardiography) the patients underwent cardiovascular magnetic resonance imaging (CMR). RESULTS/CONCLUSION: Cardiac involvement was detected by CMR in eight of nine patients (reduced left ventricular ejection fraction in 6, enlargement of left ventricular end-diastolic volume in 2 and left ventricular mass in 2) and in four patients by conventional cardiac diagnostic investigations. Two of the nine patients showed no muscle weakness or atrophy but suffered myalgias; both had cardiac manifestation of the disease. CMR is a sensitive method for detecting cardiac abnormalities in patients with LGMD2I and can be used for early detection of mild or subclinical cardiac involvement.
