OBJECTIVETo summarize the clinical features of those Duchenne and Becker muscular dystrophy (DMD and BMD) patients who are complicated with epilepsy, and try to analyze the genotype- phenotype correlation.
METHODBy a retrospective analysis of 307 patients with DMD and BMD who attended Peking University First Hospital from February 2006 to September 2014,7 patients complicated with epilepsy were identified and their clinical data were collected. The possible mechanism of epilepsy in DMD and BMD patients was proposed after analyzing the genotype-phenotype correlation.
RESULT(1) Among 307 DMD and BMD patients, 7 cases had epilepsy, the prevalence was 2. 28%. (2) The age of onset of epilepsy ranged from 8 months to 11 years. Focal seizure was the most common seizure type (6 cases) , while other seizure types were also involved, such as generalized tonic-clonic seizure. As to epilepsy syndromes, 1 boy was diagnosed as benign childhood epilepsy with centrotemporal spikes (BECT). Six patients were treated with 1 or 2 types of antiepileptic drugs and seizures were controlled well. On follow-up, 6 of the 7 children had normal mental development, while the remaining 1 patient was diagnosed as mild mental retardation. (3) DMD gene mutations of all 7 patients were analyzed. Exons deletions were found in 6 cases while point mutation was found in 1 case.
CONCLUSIONThe prevalence of epilepsy in DMD and BMD patients was higher than the prevalence in normal population. The age of onset of epilepsy varies, and focal seizure may be the most common seizure type. Some patients may also present as some kind of epilepsy syndrome, such as BECT. In most patients, seizures can be controlled well by 1 or 2 types of antiepiletic drugs. No clear correlation was found between genotype and phenotype in DMD and BMD patients who were complicated with epilepsy, probably due to limited number of cases.
