Herein we report on three siblings with Leigh syndrome (LS) harboring a homoplasmic m.3697G>A mutation (G131S) in the MT-ND1 gene. The siblings' phenotypically normal mother had the same, albeit heteroplasmic, mutation. Complex I deficiency (8% of average control values) was demonstrated in a biceps brachii muscle from one of the patients. Heteroplasmic(More)
Prader-Willi syndrome (PWS) has not been widely regarded as a disorder with a risk factor for seizures. We retrospectively investigated the frequency and characteristics of seizures and examined genotype-phenotype correlations with respect to seizures in PWS. We analyzed 142 patients with PWS and identified 31 (22%) with seizures. The most common seizure(More)
AIM To describe the characteristics of hypophosphatemia in severely disabled individuals with neurological disorders and to identify its causative factors. METHOD We retrospectively reviewed clinical data from 82 individuals with motor skills classified as sitting, rollover or bedridden. Age, gender and body mass index were compared in individuals with(More)
To evaluate the effect of corpus callosotomy (CC) on attention deficit and behavioral problems in pediatric patients with intractable epilepsy, we retrospectively investigated sequential patients who had undergone CC to control seizures. Between August 2005 and April 2010, a total of 15 patients aged between 3.1 and 17.9 years underwent CC at our institute.(More)
INTRODUCTION Corticosteroids are effective for improving motor function in patients with Duchenne muscular dystrophy (DMD), but there is no consensus on a regimen that balances efficacy and side effects. METHODS Data from three groups of DMD patients were retrospectively analyzed: those treated with 0.75mg/kg/day prednisolone every day (daily group,(More)
OBJECTIVE Antibodies against 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) have recently been associated with immune-mediated necrotizing myopathy, especially in patients with statin exposure. As the data are very limited concerning phenotypes and treatment in paediatric patients, we aimed to identify the paediatric patients positive for(More)
Genetic reversion is the phenomenon of spontaneous gene correction by which gene function is partially or completely rescued. However, it is unknown whether this mechanism always correctly repairs mutations, or is prone to error. We investigated a family of three boys with intellectual disability, and among them we identified two different mutations in(More)
Angiotensin II type-2 receptor gene (AGTR2) mutations have been recently detected in patients with mental retardation. AGTR2 plays a role in central nervous system development and cognitive functions. We identified a novel missense mutation of c.572G>A (p.G191E) in a 6-year-old boy showing severe mental retardation, pervasive developmental disorder, and(More)
Distal arthrogryposis (DA) encompasses a heterogeneous group of hereditary disorders with multiple congenital contractures predominant in the distal extremities. A total of 10 subtypes are proposed based on the pattern of contractures and association with extraarticular symptoms. DA5 is defined as a subtype with ptosis/oculomotor limitation. However,(More)
A 26-year-old woman with psychomotor developmental delay since late infancy showed rapid deterioration of her psychomotor abilities at the 11 years of age. She had gained the ability to verbally express herself and perform motor activities such as running and dancing in early childhood, but she lost the ability to verbally communicate and was unable to walk(More)
