We report the case of a 2-year-old girl who had signs of Duchenne type muscular dystrophy on clinical, electromyographic, laboratory, and pathological examination. The parents of the child are first cousins. A brother and nephew of the mother also had Duchenne type muscular dystrophy. Karyotype analysis in the proband showed both X chromosomes to be morphologically normal. The mother had very h...

A total of 102 families with Duchenne muscular dystrophy has been studied with linked DNA polymorphisms as an aid to estimating carrier risks for female relatives. Early work using probes RC8, L1.28, and pXUT23 gave very little clinically useful information because of the high recombination rates between these probes and Duchenne muscular dystrophy and the low proportion of women who were heter...

A female with Duchenne muscular dystrophy who was a carrier of a balanced translocation t(X;6)(p21;q21) is reported. Four other previously described (X;A) translocations associated with DMD share with the present case a breakpoint at Xp21. The extremely low probability of five independent (X;A) translocations having a breakpoint at Xp21 points to a non-rand association of this site with the DMD...

Duchenne muscular dystrophy is characterized by progressive muscle weakness and early death resulting from dystrophin deficiency. Spontaneous canine muscular disorders are interesting settings to evaluate the relevance of innovative therapies in human using pre-clinical trials.

Muscular dystrophies are inherited disorders in which muscle fibers are unusually susceptible to damage, leading to progressive loss of muscle structure and function. Some types of muscular dystrophy affect heart muscles, other involuntary muscles and other organs. The most common form of muscular dystrophy, Duchenne Muscular Dystrophy (DMD), is due to genetic deficiency of the protein dystroph...

Duchenne muscular dystrophy (DMD) is a severe and progressive muscle-wasting disease caused by mutations in the dystrophin gene. Although dystrophin deficiency in myofiber triggers the disease's pathological changes, the degree of satellite cell (SC) dysfunction defines disease progression. Here, we have identified chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII) hyperact...

Mutation in the dystrophin gene results Duchenne Muscular Dystrophy (DMD), an X-linked fatal neuromuscular disorder. Dystrophin deficiency can be compensated by upregulation of utrophin, an autosomal homologue of dystrophin. But the expression of utrophin in adults is restricted to myotendinous and neuromuscular junctions. Therefore utrophin upregulation throughout the muscle fiber can only be ...

There are few reports of naturally occurring muscular dystrophy in domestic animals. Herein, we describe a case of muscular dystrophy in a 4-year-old neutered male American domestic shorthair cat that died unexpectedly following anesthesia for an elective surgical procedure. Macroscopic muscular hypertrophy and histologic evidence of myofiber size variation, mineralization, myofiber degeneratio...

substances from impacted neutrophils in the lungs. Since poly-acrylonitrile membrane dialysers also activate complement but do not cause appreciable leucopenia,; it is more likely that the mechanism implicated in our patient was pulmonary leucostasis. There are several other unexplained complications of dialysis which might be related to complement activation or leucostasis or both. They includ...

Duchenne muscular dystrophy is a genetic orphan neuromuscular disease caused by mutation in the DMD gene encoding protein dystrophin. As result of developing and progressive muscle damage atrophy, children lose ability to walk, develop respiratory cardiac disorders. The core elements good care standards are early diagnosis, prevention treatment osteoporosis, daily physical therapy, regular reha...
