Idiopathic epilepsies (IEs) are a group of disorders characterized by recurrent seizures in the absence of detectable brain lesions or metabolic abnormalities. IEs include common disorders with a complex mode of inheritance and rare Mendelian traits suggesting the occurrence of several alleles with variable penetrance. We previously described a large family(More)
Severe myoclonic epilepsy of infancy (SMEI) has been long suspected to have a genetic origin. Recently mutations in the gene encoding a voltage-gated alpha-1 sodium channel subunit-SCN1A-have been identified as a common cause of SMEI. Moreover, a mutation in the gene encoding the gamma2 subunit of the GABA(A) receptor-GABRG2-has been described in a GEFS+(More)
Myoclonus has different clinical and neurophysiological features in patients with Unverricht-Lundborg (ULD) and Lafora body disease (LBD), probably because of a different cortical hyperexcitability profile. To investigate the role of intracortical inhibition in such different presentations, we used paired-pulse transcranial magnetic stimulation (TMS) in ten(More)
We describe a patient with a familial form of amyotrophic lateral sclerosis (ALS) in which a heterozygous G > A exchange at position 1087 in the SOD1 gene was detected. This mutation results in an amino acid substitution of aspartate for glycine at position 93 (G93D). The patient had a five-year history of fasciculations in all four limbs, with no clear(More)
Sporadic amyotrophic lateral sclerosis (SALS) is a motor neuron degenerative disease of unknown etiology. Current thinking on SALS is that multiple genetic and environmental factors contribute to disease liability. Since neuronal acetylcholine receptors (nAChRs) are part of the glutamatergic pathway, we searched for sequence variants in CHRNA3, CHRNA4 and(More)
The aim of our study was to analyse the natural history and clinical features of upper motor neuron- dominant (UMN-D) ALS. We studied a large series of sporadic ALS patients admitted in a single referral centre over a 23-year period. UMN-D phenotype was compared with other ALS forms, including classic ALS, flail arm and progressive muscular atrophy. Seven(More)
Benign adult familial myoclonic epilepsy (BAFME or FAME) is an autosomal dominant condition, characterized by shivering-like tremors of cortical origin, myoclonus, and epilepsy. Linkage to chromosomes 2p11.1-q12.2 and 8q23.1-q24.11 has been reported in Japanese and Italian families, respectively. We aimed to determine whether a common founder haplotype was(More)
BACKGROUND Female carriers of Duchenne muscular dystrophy (DMD), although usually asymptomatic, develop muscle weakness up to 17% of the time, and a third present cardiac abnormalities or cognitive impairment. Clinical features of DMD carriers during childhood are poorly known. PATIENTS We describe a cohort of pediatric DMD carriers, providing clinical,(More)
Familial amyloid polyneuropathy (FAP) is a rare condition caused by mutations of the transthyretin (TTR) gene and it is generally characterized by a length-dependent polyneuropathy affecting prevalently the small fibers. We reviewed clinical, electrophysiological and pathological findings of 15 unrelated patients with genetically confirmed TTR-FAP. All(More)
We report a five-generation family showing cortical tremor, myoclonus, and epilepsy, originating from Naples, Italy. Eleven members, aged 24-56 years (mean: 39.2 years), suffered from hand tremor and myoclonus, whereas generalized seizures occurred in six. Electrophysiological study confirmed the presence of cortical reflex myoclonus in all affected(More)
