How are duchennes muscular dystrophy and myotonic muscular dystrophy different?

How are duchennes muscular dystrophy and myotonic muscular dystrophy different?

Amount of Dystrophin: The two conditions differ in their severity, age of onset, and rate of progression. Mutations in the dmd gene cause duchenne and becker forms of muscular dystrophy (dmd and bmd, respectively). Mutations that lead to an abnormal version of dystrophin that retains some function usually cause bmd, while mutations that prevent the production of any functional dystrophin causes dmd. ...Read more

What are the differences between duchennes muscular dystrophy and myotonic muscular dystrophy?

What are the differences between duchennes muscular dystrophy and myotonic muscular dystrophy?

Both are inherited: neuromuscular disorders. DMD is caused by mutatation(s) on Chr. X. Onset of rapidly progressive muscle atrophy starts early in boys. Female carriers can have heart muscle disease. MD 1 is caused by mutant genes on Chr. 19; MD 2 by mutant genes on Chr. 3, Each child of a parent affected by either has a 50% chance of inheriting it, often with earlier & more severe symptoms than the parent's. ...Read more

Muscular hypertrophy is a big muscle right?

Muscular hypertrophy is a big muscle right?

Hypertrophy: The word hypertrophy means enlarged. Muscles can enlarge for various reasons, most commonly related to building muscle mass from exercise, but there are some diseases that lead to what appears to be muscle hypertrophy but is fat instead. If your muscles are enlarging involuntarily, i suggest you see your family doctor. ...Read more

Differentiate between duchenne and spinal muscular atrophy?

Differentiate between duchenne and spinal muscular atrophy?

Muscle vs motor neur: Duchenne muscular dystrophy is a disease of the muscles wherein the muscles degenerate and are replaced by fibrous and fatty tissue. Spinal muscular atrophy may look similar, but it is not a dystrophy. It is a disease of motor neurons. It is an inherited recessive disease. ...Read more

Where does duchenne muscular dystrophy strike most in the body?

Mutations in the : dystrophin gene, Xp21.2-p21.1, causes weakness in large, then small, skeletal muscles. Weakness of heart muscle, smooth muscle of GI tract & urinary tracts, Speech Sound Disorder, Intellectual Disability, Specific Learning Disability & behavior problems occur in some boys. Carrier girls may have cardiomyopathy. Specific mutations determine manifestations in boys & carrier girls. See mda.org. ...Read more

What does congenital muscular dystrophy mean?

Muscle disease: Congenital myopathy means a disease of muscle present since birth, usually inherited. The congenital myopathies are due to several genetic defects, mostly associated with muscle energy use. Usually, people have muscle weakness or damage that is mild and presents in teen or older years. Muscular dystrophy is a congenital myopathy but much more severe and not usually under this name. ...Read more

What does "duchene muscular dystrophy" mean?

What does "duchene muscular dystrophy" mean?

Genetic muscle issue: Dmd is a genetic disorder in which there is a mutation in dystrophin, a structural protein found in muscle cell membrane. It causes progressive weakness that typically starts in the legs and pelvis, but eventually spreads throughout the body and also compromises breathing. There are symptomatic treatments, but no cure. ...Read more

What causes duchenne muscular dystrophy?

Hereditary: It is inherited because of a defective gene on the x chromosome (female sex chromosome). It is referred to as a "sex-linked recessive" inheritance pattern. Girls get two x chromosomes, and the healthy one overrules the unhealthy gene, preventing girls from contracting the disorder. Boys get an x and a y. If the x has the defective gene, there is no corresponding gene on the y to overrule it. ...Read more
