Muscular dystrophies are caused by mutations in genes, usually those involved in making muscle proteins. [2] The muscle protein, dystrophin, is in most muscle cells and works to strengthen the muscle fibers and protect them from injury as muscles contract and relax. [3] It links the muscle membrane to the thin muscular filaments within the cell.
Congenital muscular dystrophies are autosomal recessively-inherited muscle diseases. They are a group of heterogeneous disorders characterized by muscle weakness which is present at birth and the different changes on muscle biopsy that ranges from myopathic to overtly dystrophic due to the age at which the biopsy takes place.
Hyaluronic acid (/ ˌ h aɪ. ə l j ʊəˈr ɒ n ɪ k /; [1] [2] abbreviated HA; conjugate base hyaluronate), also called hyaluronan, is an anionic, nonsulfated glycosaminoglycan distributed widely throughout connective, epithelial, and neural tissues.
Ullrich congenital muscular dystrophy; Other names: Scleroatonic muscular dystrophy [1] Autosomal recessive pattern is the inheritance manner of this condition: Symptoms: Muscle weakness [2] Types: UCMD1, UCMD2: Causes: Mutations in the COL6A1, COL6A2, COL6A3, and COL12A1 gene [3] Diagnostic method: Physical exam, Medical history [3] Medication
Myotonic dystrophy is caused by a genetic mutation in one of two genes. Mutation of the DMPK gene causes myotonic dystrophy type 1 (DM1). Mutation of CNBP gene causes type 2 (DM2). [1] DM is typically inherited, following an autosomal dominant inheritance pattern, [1] and it generally worsens with each generation. [1]
Mexico President Claudia Sheinbaum said Wednesday that surveillance drone flights by the U.S. government over Mexico are occurring in collaboration with and at the request of her government.
Duchenne muscular dystrophy is a rare progressive disease that eventually affects all voluntary muscles and involves the heart and breathing muscles in later stages. Life expectancy is estimated to be around 25–26, [18] [59] but this varies. People born with Duchenne muscular dystrophy after 1990 have a median life expectancy of approximately ...
Spinal and bulbar muscular atrophy (SBMA), popularly known as Kennedy's disease, is a rare, adult-onset, X-linked recessive lower motor neuron disease caused by trinucleotide CAG repeat expansions in exon 1 of the androgen receptor (AR) gene, which results in both loss of AR function and toxic gain of function.
