| Popis: | Muscular dystrophies are a heterogeneous group of inherited dis-eases that cause progressive muscle weakness. The association of epi-lepsy with some of these diseases has been previously described andhas most commonly been found for Fukuyama-type muscular dystro-phy due to alterations in cerebral neuronal migration[1]. Among mus-cular dystrophies, limb-girdle muscular dystrophies (LGMDs)represent the fourth most common group, with a prevalence of 1.63per 100, 000 individuals[2]. The diseases in this group share a commonphenotype involving progressive weakness of the scapular and pelvicgirdles that starts after 2 years of age and can be accompanied by differ-ent degrees of elevation in blood creatine kinase (CK) levels and by var-ious anatomic pathologicalfindings. LGMDs are subdivided into LGMD1and LGMD2 depending on whether the inheritance is dominant or re-cessive, respectively. LGMD2A, which is caused by deficiency of thecalpain 3 protein owing to mutations in theCAPN3gene, is the mostcommon form of LGMD in Europe and America[2]. Its associationwith epilepsy has been described in only two isolated cases[1, 3], bothof them on the spectrum of genetic generalised epilepsies (GGEs). Thelatter are the most common group of epilepsies with genetic aetiology, accounting for 15–20% of all epilepsy cases[4]. Nonetheless, none of thegenes usually involved in monogenic epilepsies seem to play a majorrole in GGE, probably indicating a polygenic predisposition to GGE andtherefore a complex inheritance pattern[5]. Here, we describe a family... |
