We studied 19 symptomatic female carriers of the Duchenne muscular dystrophy (DMD) gene. Most of these dystrophinopathy patients had had an erroneous or ambiguous diagnosis prior to dystrophin immunofluorescence testing. We assessed clinical severity by a standardized protocol, measured X-chromosome inactivation patterns in blood and muscle DNA, and(More)
BACKGROUND We describe a severe form of congenital myasthenic syndrome (CMS) associated with congenital nephrosis and ocular malformations caused by two truncating mutations in the gene encoding the laminin beta2 subunit (LAMB2). METHODS AND RESULTS Mutational analysis in the affected patient, who has a history of a serious untoward reaction to treatment(More)
A double-blind crossover study with imipramine was conducted in 10 patients with absence and myoclonic-astatic seizures who had not responded to conventional medications. Imipramine produced a significant initial decrease in seizure frequency in 5 of the 10 patients, and in 2 patients the beneficial effect was maintained for more than 1 year. An open trial(More)
The dystrophinopathies are muscle disorders due to an abnormality of an Xp21-linked gene which produces the dystrophin protein. The most common of these disorders are the Duchenne and Becker muscular dystrophies. Modern molecular genetic techniques enable reliable diagnosis and prognosis in many patients, but there are occasional pitfalls. Furthermore, the(More)
Three siblings, devoid of hair at birth, had an unusual autosomal recessive disorder characterized by universal congenital alopecia, microcephaly, seizures, psychomotor retardation, and severe growth failure. Metabolic and chromosome studies were normal. Skin biopsies disclosed immature hair follicles, some of which were filled with keratotic material but(More)
A 15-year-old boy is described with myasthenia gravis, hemophilia A, positive HTLV-III serology, antithyroglobulin and antimicrosomal antibodies, and laboratory evidence of altered cell-mediated immunity. Treatment with pyridostigmine produced dramatic clinical improvement. The results of this patient raise the possibility of myasthenia gravis as the sole(More)
