Epileptic encephalopathies are increasingly thought to be of genetic origin, although the exact etiology remains uncertain in many cases. We describe here three girls from two nonconsanguineous families affected by a clinical entity characterized by dysmorphic features, early-onset intractable epilepsy, intellectual disability, and cortical blindness.

Three Duchenne muscular dystrophy (DMD) patients received injections of myogenic cells obtained from skeletal muscle biopsies of normal donors. The cells (30 x 10 (6)) were injected in 1 cm3 of the tibialis anterior by 25 parallel injections. We performed similar patterns of saline injections in the contralateral muscles as controls. The patients received(More)
A 26-years old Duchenne muscular dystrophy (DMD) patient received normal muscle-precursor cells, proliferated in vitro and implanted in a thenar eminence, biceps brachii, and in a portion of a gastrocnemius by injections placed 1mm from each other or less. Saline was injected in the contralateral gastrocnemius. The patient was immunosuppressed with(More)
A clinical trial was conducted to test a new protocol of normal muscle precursor cell (MPC) allotransplantation in skeletal muscles of patients with Duchenne muscular dystrophy (DMD). Cultured MPCs obtained from one of the patient's parents were implanted in 0.25 or 1 cm of a Tibialis anterior in 9 patients with DMD. MPC injections were placed 1 to 2 mm(More)
Leukodystrophies are a heterogeneous group of disorders associated with abnormal central nervous system white matter. The clinical features invariably include upper motor neuron signs and developmental regression with or without other neurological manifestations. The objective of this study was to characterize clinically and genetically a new form of(More)
Hereditary spastic paraplegias (HSPs) are characterized by progressive lower limb spasticity and weakness. Mutations in the SPG3A gene, which encodes the large guanosine triphosphatase atlastin, are the second most common cause of autosomal dominant hereditary spastic paraplegia. In a large SPG3A screen of 70 hereditary spastic paraplegia subjects, a novel(More)
