Duchenne muscular dystrophy is clinically characterised by progressive muscle weakness and a gradual increase in the size of some affected muscles, especially calf muscles. The extent of calf enlargement is usually determined by subjective visual assessment. The purpose of this study was to determine the extent of calf muscle enlargement in Duchenne muscular dystrophy (DMD) patients compared wi...

Emery-Dreifuss muscular dystrophy (EDMD) is an X-linked humeroperoneal dystrophy associated with cardiomyopathy that is distinct from the Duchenne and Becker forms of X-linked muscular dystrophy. Linkage analysis has assigned EDMD to the terminal region of the human X chromosome long arm. We report here further linkage analysis in two multigenerational EDMD families using seven Xq28 marker loci...

Myofibrillar protein catabolism has been calculated in a variety of neuromuscular diseases from the amount of 3-methylhistidine excreted in the urine. It was found to be significantly raised in Duchenne type muscular dystrophy, motor neurone disease, polymyositis, and thyrotoxic myopathy. In Becker type muscular dystrophy the level was slightly raised. It was normal in scapuloperoneal and limb...

The application of molecular diagnostic techniques has greatly improved the diagnosis, carrier detection, prenatal testing and genetic counseling for families with Duchenne and Becker muscular dystrophy (D/BMD) in India. The prediction of Duchenne muscular dystrophy (DMD) patients to have out-framed deletions and Becker's muscular dystrophy (BMD) patients to have in-frame deletions of dystrophi...

Autophagy has recently emerged as an important cellular process for the maintenance of skeletal muscle health and function. Excessive autophagy can trigger muscle catabolism, leading to atrophy. In contrast, reduced autophagic flux is a characteristic of several muscle diseases, including Duchenne muscular dystrophy, the most common and severe inherited muscle disorder. Recent evidence demonstr...

Duchenne muscular dystrophy is the most common form of muscular dystrophy. Genetic and biochemical research over the years has characterized the cause, pathophysiology and development of the disease providing several potential therapeutic targets and/or biomarkers. High throughput - omic technologies have provided a comprehensive understanding of the changes occurring in dystrophic muscles. Mur...

We present a case of an unusual triad in pediatric neurology: a currently 12-year-old boy with cerebral palsy and epilepsy who was later also diagnosed with Duchenne muscular dystrophy. We describe the clinical path that resulted in this exceptional diagnosis. This case report illustrates how different neurological disorders may overshadow each other. In addition, it demonstrates that every chi...

The PKU sample, if taken after the 3rd day, is suitable for Duchenne muscular dystrophy screening using creatine phosphokinase (CPK) levels. 101 babies (53 girls and 48 boys) had CPK levels measured on filter paper blood specimens taken by heel prick on the 1st and 4th days of life. The method used was that described by Zellweger and Antonik (1975). The CPK levels were markedly raised on the 1s...

A female with Duchenne muscular dystrophy, diagnosed at the age of 3 years 8 months, is reported. Chromosome studies revealed an X;autosome reciprocal translocation t(X;5) (p21.2;q31.2). With the BrdU-Hoechst 33258-Giemsa technique, there was nonrandom preferential inactivation of the normal X. Our patient is the ninth reported case of Duchenne muscular dystrophy associated with an X;autosome t...
