Muscular dystrophies are a heterogeneous class of inherited disorders presenting with different clinical, genetic, and biochemical features. Muscular dystrophies include Duchennemuscular dystrophy (DMD) and Becker muscular dystrophy (BMD) myotonic dystrophy (DM), oculopharyngeal muscular dystrophy (OPMD), facioscapulohumeral muscular dystrophy (FSHD), limb-girdle muscular dystrophy (LGMD), dist...

ulrich congenital muscular dystrophy is an autosomal recessive disorder of collagen type vi-related disorders. this condition presents with early onset proximal joint contractures, muscle weakness and hyperelasticity of the distal joints. prominent calcanei are common. muscle weakness is so profound that children never achieve the ability to walk independently or walk for only short periods. se...

Ullrich congenital muscular dystrophy (UCMD) and Bethlem myopathy are inherited muscle disorders caused by mutations of genes encoding the extracellular matrix protein collagen VI (ColVI). Mice lacking ColVI (Col6a1(-/-)) display a myopathic phenotype associated with ultrastructural alterations of mitochondria and sarcoplasmic reticulum, mitochondrial dysfunction with abnormal opening of the pe...

Ullrich syndrome is a recessive congenital muscular dystrophy affecting connective tissue and muscle. The molecular basis is unknown. Reverse transcription-PCR amplification performed on RNA extracted from fibroblasts or muscle of three Ullrich patients followed by heteroduplex analysis displayed heteroduplexes in one of the three genes coding for collagen type VI (COL6). In patient A, we detec...

Background: The TTN gene is related to a broad phenotype spectrum including tibial muscular dystrophy, hereditary myopathy with respiratory failure, limb girdle dystrophy 2J and dilated or hypertrophic cardiomyopathy. In 2014, Chauveau et al, described phenotypes cardiac septal defects, left ventricular non-compaction, Emery-Dreifuss arthrogryposis. 2020, Savarese showed most of patients bialle...

Several abnormalities in the central nervous system were shown in patients with progressive muscular dystrophy using computerised tomography (CT) scans, electroencephalograms, psychometry, and ophthalmological methods. In congenital muscular dystrophy, the most characteristic finding in the CT scan was a low density area in the white matter, seen in 14 (56%) out of 25 cases. In Duchenne dystrop...

Hypotonia beginning at birth or early in the neo-natal period can be caused by one of the following: (1) infantile muscular atrophy; (2) benign congenital hypotonia; (3) symptomatic hypotonia (Walton, 1960). Infantile muscular atrophy is an established clinicopathological disorder in which muscular atrophy is secondary to disease of the motor neurone. Benign congenital hypotonia is characterize...
