BACKGROUND Myotonic Dystrophy type 1 (DM1) is one of the most heterogeneous hereditary disease in terms of age of onset, clinical manifestations, and severity, challenging both medical management and clinical trials. The CTG expansion size is the main factor determining the age of onset although no factor can finely predict phenotype and prognosis.(More)
Congenital poikiloderma is characterized by a combination of mottled pigmentation, telangiectasia, and epidermal atrophy in the first few months of life. We have previously described a South African European-descent family affected by a rare autosomal-dominant form of hereditary fibrosing poikiloderma accompanied by tendon contracture, myopathy, and(More)
P0 is a transmembrane protein of the immunoglobulin superfamily that plays a role in myelin structure and function. Myelin protein zero gene (MPZ) mutations usually cause a demyelinating variant of Charcot-Marie-Tooth disease type 1B (CMT1B), but there is a wide spectrum of phenotypic manifestation of these mutations. We describe three patients from one(More)
Duchenne Muscular Dystrophy (DMD) is a complex process involving multiple pathways downstream of the primary genetic insult leading to fatal muscle degeneration. Aging muscle is a multifactorial neuromuscular process characterized by impaired muscle regeneration leading to progressive atrophy. We hypothesized that these chronic atrophying situations may(More)
BACKGROUND AND PURPOSE To provide a detailed phenotypical description of seronegative patients with generalized myasthenia gravis and antibodies to clustered acetylcholine receptors (AChRs) and to assess their frequency amongst a French seronegative generalized myasthenia gravis (SNMG) population. METHODS A French SNMG database was created and the sera(More)
OBJECTIVES Retrospective study over the last 30 years of life expectancy in patients suffering from Duchenne muscular dystrophy (DMD). Analysis of the role of ventilatory assistance and causes of death. PATIENTS AND METHODS One hundred and nineteen adult DMD patients were hosted during 1981 to 2011 at AFM Yolaine de Kepper centre, Saint-Georges-sur-Loire,(More)
Seipinopathies are a group of inherited diseases affecting upper and lower motor neurons due to mutations in the Berardinelli-Seip congenital lipodystrophy 2 gene (BSCL2). We report a French family carrying the N88S mutation in the BSCL2 gene. A 12-yr-old girl complained of bilateral asymmetrical pes cavus with right hand motor deficit and amyotrophy,(More)
UNLABELLED We report the case of a pregnant woman presenting with Guillain-Barré syndrome in which her neurologic status worsened immediately after delivery under epidural analgesia. We believe that the anesthetic technique may have played a role in the disease progression. Because of this potential association, the risks of worsening neurologic status(More)
BACKGROUND Neurologic involvement occurs in approximately 25% of patients with primary Sjögren's syndrome. Manifestations are diverse and can affect the entire neuroaxis. Central nervous system dysfunction involves the brain as well as the spinal cord and may recur over time. Due to a variety of presentations, Sjögren's syndrome with neurologic involvement(More)
The decrease in muscle strength in patients with Duchenne muscular dystrophy (DMD) is mainly explained by a decrease in the number of active contractile elements. Nevertheless, it is possible that other electrochemical and force transmission processes may contribute. The present study aimed to quantify the effect of DMD on the relative contribution of(More)
