Duchenne Muscular Dystrophy 2022: Epidemiology, Etiology, Pathophysiology, Symptoms, Diagnosis and Treatment Guidelines – ResearchAndMarkets.com

DUBLIN–(BUSINESS WIRE)–The “Duchenne Muscular Dystrophy – Opportunity Assessment and Forecast to 2030” report has been added to ResearchAndMarkets.com’s offering.

Duchenne muscular dystrophy (DMD) is a rare genetic disorder characterized by progressive muscle degeneration and weakness due to the alterations of a protein called dystrophin. Dystrophin is part of a group of proteins, which together form the dystrophin-associated protein complex (DPC). These proteins form a transmembrane scaffold that are crucial for the structure of the muscle tissue, protect muscle fibers from injury during muscle contraction and relaxation, and also serve integral functions in cell signalling. DMD is one of four conditions known as dystrophinopathies, and it is classified as the most severe end of the spectrum, with a lack of functional dystrophin. The disease is an X-linked recessive disorder mainly affecting males, with female carriers. While females are generally unaffected, some may show a milder phenotype (“manifesting carriers”) such as cardiac changes, mild muscle weakness, and muscle cramping.

Lack of dystrophin in muscle cells causes them to be fragile and easily damaged. DMD is progressive and most affected individuals require a wheelchair by adolescence. Serious life-threatening conditions including cardiomyopathy and respiratory difficulties ultimately develop and lead to mortality of DMD patients between 19 and 25 years of age; however, the publisher’s primary research revealed that survival has increased in recent years to the 3rd decade of life.
