Background: The association of limb-girdle muscular dystrophy (LGMD) with other neurological disorders is uncommon. Case presentation: We report a 25-year-old female with LGMD who suffered from slowly progressive proximal muscular weakness and atrophy since she was 12 years of age. The patient recently presented with acute loss of left side visual acuity. After evaluation, findings were sugges...

This report concerns two families in which the index patients are sporadic cases of a benign form of muscular dystrophy. In both families the sisters of the patients have married a close relative. The respective risks for a child of these consanguineous marriages being affected with either X linked Becker muscular dystrophy or autosomal recessive limb girdle muscular dystrophy is calculated usi...

We report a case of birdshot chorioretinopathy (BSCR) in a patient with facioscapulohumeral muscular dystrophy (FSHD). A 40-year-old male with history of facioscapulohumeral muscular dystrophy with significant facial diplegia and lagophthalmos presents for an evaluation of bilateral choroiditis with vasculitis and optic disc edema. Clinical examination included fundus and autofluorescence photo...

Human tibial muscular dystrophy and limb-girdle muscular dystrophy 2J are caused by mutations in the giant sarcomeric protein titin (TTN) adjacent to a binding site for the muscle-specific protease calpain 3 (CAPN3). Muscular dystrophy with myositis (mdm) is a recessive mouse mutation with severe and progressive muscular degeneration caused by a deletion in the N2A domain of titin (TTN-N2ADelta...

BACKGROUND The muscular dystrophies target muscle groups differentially. In mouse models of muscular dystrophy, notably the mdx model of Duchenne Muscular Dystrophy, the diaphragm muscle shows marked fibrosis and at an earlier age than other muscle groups, more reflective of the histopathology seen in human muscular dystrophy. METHODS Using a mouse model of limb girdle muscular dystrophy, the...

MANY observers have reported pathologic changes in the myoeardium of patients with muscular dystrophy similar to those in the skeletal muscles.'-8 Clinical evidence of involvement of the heart has also been noted, consisting of persistent tachycardia,9 10 arrhythmias,10 congestive heart failure, chest pain, cardiac enlargement, changes in heart sounds, murmurs, electrocardiographic alterations ...

Introduction. First, we will give a general overview of the generation of muscle contraction in a normal cell. Skeletal muscle contraction is accomplished by the generation of a neuronal action potential that terminates at the neuromuscular synapse. The neuronal action potential (AP) stimulates sodium channels in the neuronal axon that propagates the signal along the axon. As the AP reaches the...

Are things clearer now? Yes. A breakthrough came in 1987 when the causative gene for the most common severe form of MD, Duchenne muscular dystrophy (DMD — the field is rich in eponyms, too) was found. Since then, the genes affected in many MDs have been discovered, enabling classification and diagnosis to be put on a much more secure footing. Some traditional disease categories have split as a ...

The muscular dystrophy research community is at a watershed moment. Our understanding of the molecular, cellular, and physiological underpin­ nings of the muscular dystrophies continues to increase and has revealed several therapeutic tar­ gets. For the first time, investigational therapies are reaching the final stages of review by United States regulatory agencies. Yet, as we learn more about...

A 60-year-old man diagnosed clinically with Becker's muscular dystrophy 20 years ago by another physician presented with gradually progressive proximal muscle weakness since teenage years. Family history revealed a strong paternal familial inheritance pattern of similar distribution of weakness-face, forearm flexion, knee extension and foot dorsiflexion. Work-ups revealed B12 deficiency and all...
