We report on the genotype-phenotype correlation in 7 patients with classical lissencephaly carrying a heterozygous subtle mutation in the LIS1 gene. Six patients, showed a mutation predicted to encode for a truncated protein, and one mutation altered a splicing site, resulting in skipping of exon 4. Western blot analysis performed on the lymphoblastoid cell(More)
In rats, horseradish peroxidase crystals were injected in motor cortical foci functionally identified by means of the motor effects evoked by electrical stimulations. The location in the thalamus of the neurons linked to different motor cortical foci was studied. Thalamic neurons were retrogradely labeled in both "motor" (ventralis lateralis and ventralis(More)
The purpose of this study was to compare the electromyographic (EMG) behavior of the triceps surae (TS), tibialis anterior (TA), quadriceps and hamstring muscles of the lower limbs during self-initiated free gait in a group of patients (n = 15) with Parkinson's disease (PD), when OFF and ON L-Dopa, with that of normal controls. When OFF L-Dopa, we observed(More)
Canavan disease (CD) is a rare autosomal recessive disorder characterized by macrocephaly and progressive leukodystrophy. Up to now biopsy or necropsy were required to define the diagnosis. Recently the disease has been related to N-acetylaspartic aciduria and deficiency of aspartoacylase, an enzyme possibly involved in the myelin synthesis. These(More)
We investigated the effects of the somatosensitive and sensory afferent inputs on the thalamic generators of sleep spindles (SS) in adult subjects affected by posterior funiculi lesions (five subjects), deafness (four subjects) or blindness (four subjects). The density, duration and frequency of SS, as well as the index of spindling, were analyzed during(More)
Pontocerebellar hypoplasia type 2 (PCH2) is a very rare autosomal recessive disorder. We report two unrelated female patients born to consanguineous parents presenting with this condition. Patient 1 showed a classical clinical/neuroradiological phenotype of PCH2 with dyskinesia/dystonia. Patient 2 had a neonatal onset of PCH2 with polyhydramnios, apneic(More)
Schinzel-Giedion syndrome (SGS) is a rare disorder with a likely autosomal recessive pattern of inheritance which is characterized by several facial dysmorphisms, midface hypoplasia, multiple skeletal anomalies including short and sclerotic skull base, short neck, and post-axial polydactyly. Cardiac and urogenital malformations are also present.(More)
Intracranial calcification and microcephaly, which represent the main clinical features of the TORCH-syndrome, can also be determined by a rare autosomal recessive infection-like condition named pseudo-TORCH syndrome. This emerging entity has been registered in eight families so far. We report on five patients from three unrelated Italian families affected(More)
