Mutations in POMT1 have been identified in Walker-Warburg syndrome and in patients with limb-girdle muscular dystrophy and mental retardation (LGMD2K). The authors report new POMT1 mutations in three unrelated children with severe motor impairment, leg hypertrophy, and mental retardation but without brain and ocular malformations. These patients are similar(More)
BACKGROUND Muscle-eye-brain disease is a congenital muscular dystrophy with eye and brain involvement due to POMGnT1 mutations. OBJECTIVE To describe the clinical and molecular features of 3 Italian patients with POMGnT1 mutations. DESIGN Case reports. PATIENTS One patient had muscle and brain abnormalities without eye involvement. Two patients had a(More)
OBJECTIVE To perform an extensive search for genomic rearrangements by microarray-based comparative genomic hybridization in patients with epilepsy. DESIGN Prospective cohort study. SETTING Epilepsy centers in Italy. PATIENTS Two hundred seventy-nine patients with unexplained epilepsy, 265 individuals with nonsyndromic mental retardation but no(More)
Defects in glycosylation of alpha-dystroglycan are associated with several forms of muscular dystrophies. Mutations in POMT2 gene have been identified in patients with congenital muscular dystrophy and brain involvement, either characterized by a Walker-Warburg/muscle-eye-brain phenotype, or by microcephaly, mental retardation, and cerebellar hypoplasia. We(More)
Alterations in the formation of brain networks are associated with several neurodevelopmental disorders. Mutations in TBC1 domain family member 24 (TBC1D24) are responsible for syndromes that combine cortical malformations, intellectual disability, and epilepsy, but the function of TBC1D24 in the brain remains unknown. We report here that in utero TBC1D24(More)
OBJECTIVE To evaluate the phenotypic spectrum associated with mutations in TBC1D24. METHODS We acquired new clinical, EEG, and neuroimaging data of 11 previously unreported and 37 published patients. TBC1D24 mutations, identified through various sequencing methods, can be found online (http://lovd.nl/TBC1D24). RESULTS Forty-eight patients were included(More)
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)
OBJECTIVE Alterations of sphingolipid metabolism are implicated in the pathogenesis of many neurodegenerative disorders. METHODS We identified a homozygous nonsynonymous mutation in CERS1, the gene encoding ceramide synthase 1, in 4 siblings affected by a progressive disorder with myoclonic epilepsy and dementia. CerS1, a transmembrane protein of the(More)
Neuromyotonia is a disorder of peripheral nerve hyperexcitability characterized by myokymia, muscle cramps and stiffness, delayed muscle relaxation after contraction (pseudomyotonia), and hyperhidrosis, associated with well described spontaneous electromyographic features. It is usually an acquired disorder associated with autoantibodies against neuronal(More)
