Limb-girdle3

• LGMD2A is the most common form of limb-girdle muscular dystrophy, accounting for about 30 percent of cases. (nih.gov)
• Additionally, CRD has three therapies in the pipeline for the treatment of types 2b, 2g, and 2i of Limb-girdle muscular dystrophy. (cureraredisease.org)
• Between 1909 and 1954, many individual case reports of primary muscle disease with a limb-girdle distribution of weakness were published. (medscape.com)

Affects boys2

• BMD primarily affects boys and men, who inherit the disease through their mothers. (mda.org)
• The condition most often affects boys due to the way the disease is inherited. (medlineplus.gov)

Neurological2

• Neurological diseases are different disorders which affect the brain and nervous system. (mdac.ca)
• A neurological exam can diagnose SMA disease. (nortonchildrens.com)

Myopathy1

• From the time she was 17 months old until she was finally diagnosed with Bethlem myopathy , a type of congenital muscular dystrophy (CMD) , at age 44, she put her health and hope into the hands of a series of pediatricians, orthopedists, neurologists, and surgeons. (mdaquest.org)

Muscle weakness2

• Muscular dystrophy is not one, but multiple health issues that lead to loss of muscle mass and muscle weakness. (mdac.ca)
• The disease is characterised by a loss of motor neurones and resultant muscle weakness and inability to carry out co-ordinated motor tasks including breathing. (abdn.ac.uk)

Phenotype1

• We will now determine the ability of the best PTM to restore normal muscular phenotype, in vitro in KI myoblasts/myotubes and in vivo after injection of AAV-PTM vectors in new born homozygous and adult heterozygous mice. (biomedcentral.com)

Involvement1

• Increased levels of ALP are also associated with Von Recklinghausen's disease with bone involvement and malignant infiltrations of bone. (cdc.gov)

Weakness2

• The early onset of contractures before and slowly progressive weakness and atc the onset of any significant weakness is rophy in a humeroperoneal distribution unique to this disease. (who.int)
• At that time, the differentiation between the spinal muscular atrophies and weakness associated with central nervous system disorders and primary muscle disease had not been established. (medscape.com)

Type4

• This type of diseases appears when the neurons with functions in movement become damaged or die. (mdac.ca)
• It is the most common type of muscular dystrophy. (wikipedia.org)
• Type 1 SMA, or Werdnig-Hoffman disease, is usually diagnosed within the first six months of life. (healthline.com)
• Type 3 SMA, or Kugelberg-Welander disease, is usually diagnosed by age 3 but can sometimes appear later in life. (healthline.com)

Degeneration1

• Amyotrophic lateral sclerosis (ALS), also known as Charcot's disease and Lou Gehrig's disease, is a disease of unknown cause characterized by slowly progressive degeneration of upper motor neurons (UMNs) and lower motor neurons (LMNs). (medscape.com)

Scoliosis1

• Children with SMA disease are at increased risk for scoliosis. (nortonchildrens.com)

Biopsy1

• Confirmation of muscular sarcocystosis requires biopsy and histologic observation of sarcocysts in muscle. (cdc.gov)

Genes5

• Muscular dystrophy is a general term for a group of inherited diseases involving defects in the genes responsible for normal muscle functioning. (drweil.com)
• Increased knowledge of genomics over the past two decades has made it apparent that the traditional category of genetic diseases represents only those conditions in which the genetic contribution is particularly marked, whereas in fact diseases can be arrayed along a spectrum representing the varied contribution of genes and the environment. (who.int)
• The interaction of genes with each other and with environmental factors underlies many aspects of human health and disease. (who.int)
• These conditions are described as genetic diseases because a defect in one or more genes or chromosomes leads to a pathological condition. (who.int)
• for instance, carriers of sickle-cell disease and thalassaemia genes may be protected from contracting malaria. (who.int)

Treatment3

• What is the treatment for the muscular dystrophy? (mdac.ca)
• Disease areas Broad brings people together to advance the understanding and treatment of disease. (broadinstitute.org)
• In this review, we discuss our current understanding of the contribution of NMJ dysfunction in SMA disease pathogenesis, and also provide an overview of therapies currently under preclinical and clinical development for treatment of SMA. (benthamscience.com)
