Congenital myopathies and muscular dystrophies constitute a genetically and phenotypically heterogeneous group of rare inherited diseases characterized by muscle weakness and atrophy, motor delay and respiratory insufficiency. To date, curative care is not available for these diseases, which may severely affect both life-span and quality of life. We discuss prenatal diagnosis and genetic counse...
Freeman-Sheldon Syndrome (FSS), or distal arthrogryposis type 2A, is a rare congenital myopathy and dysplasia characterized by multiple contractures, abnormalities of the head and face, defective development of the hands and feet and skeletal malformations. The facial muscle contracture produces the typical “whistling face” appearance. Anesthetic issues include difficult intravenous access, dif...
Multinucleate cellular syncytial formation is a hallmark of skeletal muscle differentiation. Myomaker, encoded by Mymk (Tmem8c), is a well-conserved plasma membrane protein required for myoblast fusion to form multinucleated myotubes in mouse, chick, and zebrafish. Here, we report that autosomal recessive mutations in MYMK (OMIM 615345) cause Carey-Fineman-Ziter syndrome in humans (CFZS; OMIM 2...
Antisense therapy is an approach to fighting diseases using short DNA-like molecules called antisense oligonucleotides. Recently, antisense therapy has emerged as an exciting and promising strategy for the treatment of various neurodegenerative and neuromuscular disorders. Previous and ongoing pre-clinical and clinical trials have provided encouraging early results. Spinal muscular atrophy (SMA...
Loss-of-function mutations in the myotubularin gene (MTM1) cause X-linked myotubular myopathy (XLMTM), a fatal, congenital pediatric disease that affects the entire skeletal musculature. Systemic administration of a single dose of a recombinant serotype 8 adeno-associated virus (AAV8) vector expressing murine myotubularin to Mtm1-deficient knockout mice at the onset or at late stages of the dis...
X-linked recessive myotubular myopathy (XLMTM) is a severe congenital muscle disorder caused by mutations in the MTM1 gene and characterized by severe hypotonia and generalized muscle weakness in affected males. It is generally a fatal disorder during the neonatal period and early infancy. The diagnosis is based on typical histopathological findings on muscle biopsy, combined with suggestive cl...
Mitochondrial myopathy, lactic acidosis, and siderobastic anemia (MLA SA) syndrome is one of the newly reported mitochondrial diseases, seven cases of which have been reported. We report a child with inflammatory myopathy, sideroblastic anemia and lactic acidosis .The patient is a 8.5 year old boy with normal cognitive function suffering from chronic progressive weakness in lower extremities, ...
All the diagnostic muscle biopsy cases were collected from the file of Department of Pathology, Seoul National University Hospital during June 1976 to December 1978. Slides were reviewed and correlated with clinical informations. Two hundred seventy four cases showed pathological changes, which were classified into six large groups (Table 1). Neurogenic atrophy was most common, 97 cases (35%), ...
Collagen VI is an extracellular matrix protein expressed in several tissues including skeletal muscle. Mutations in COL6A genes cause Bethlem Myopathy (BM), Ullrich Congenital Muscular Dystrophy (UCMD) and Myosclerosis Myopathy (MM). Collagen VI deficiency causes increased opening of the mitochondrial permeability transition pore (mPTP), leading to ultrastructural and functional alterations of ...
Abnormal endocrine indices and myopathy have been variably present in two brothers with Bloom's syndrome (congenital teleangiectatic erythema, hypersensitivity to light, and growth retardation). These consisted of: (1) growth retardation with height and weight below the third centiles; in the younger one at age 14, hypoglycaemia failed to elicit a rise in growth hormone but did so in the older ...
