how is muscular dystrophy contracted?
through DNA
through a virus
through certain forms of cancer
through old age
Muscular dystrophy is not contracted or transmitted like a typical infection or disease. It is primarily a genetic disorder that is inherited from parents who carry the faulty genes. It occurs due to mutations in specific genes that control the structure and function of muscle fibers. These genetic mutations can be present from birth or acquired during conception. Muscular dystrophy is not caused by viruses, certain forms of cancer, or old age.
Muscular dystrophy is not contracted in the traditional sense like a viral or bacterial infection. It is primarily an inherited disorder caused by genetic mutations. These mutations affect the genes responsible for the structure and function of muscles. The most common type of muscular dystrophy, called Duchenne muscular dystrophy, is caused by a mutation in the dystrophin gene on the X chromosome. This mutation prevents the production of a protein called dystrophin, which is crucial for maintaining the integrity of muscle fibers. Since muscular dystrophy is a genetic disorder, it is not associated with viral infections, certain forms of cancer, or old age.
Muscular dystrophy is primarily caused by genetic mutations or abnormalities in a person's DNA. It is not contracted through a virus, certain forms of cancer, or old age. Let me elaborate on how genetic mutations can lead to muscular dystrophy.
Muscular dystrophy is a group of genetic disorders characterized by progressive muscle weakness and degeneration. These disorders result from mutations in specific genes responsible for the structure and function of muscles. The most common form of muscular dystrophy is Duchenne muscular dystrophy (DMD), which primarily affects boys.
DMD is caused by a mutation in the gene that codes for a protein called dystrophin. Without functional dystrophin, muscle fibers become fragile and prone to damage, leading to the progressive loss of muscle strength. The mutation responsible for DMD is usually inherited from a carrier mother, as the gene is located on the X chromosome.
There are various types of muscular dystrophy, each caused by mutations in different genes. For example, Becker muscular dystrophy (BMD) is another type caused by mutations in the dystrophin gene, but with a different effect on the protein.
To determine if an individual has muscular dystrophy and to identify the specific type, genetic testing is typically performed. This involves analyzing a person's DNA to check for mutations in the genes associated with muscular dystrophy.
In summary, muscular dystrophy is contracted through genetic mutations that affect the structure and function of muscles. It is not caused by a virus, certain forms of cancer, or old age. Genetic testing is essential for diagnosing specific types of muscular dystrophy.
