Becker muscular dystrophy (BMD) is a genetic condition that leads to progressive muscle wasting due to a mutation in the gene that makes a muscle-supporting protein called dystrophin. Walking problems are usually noticed around age 15–16. Diagnosis is suggested clinically and is confirmed by genetic testing or analysis of the protein product (dystrophin) of the mutated gene. Your email address will not be published. Some providers prescribe steroids to help keep a patient walking for as long as possible. Becker muscular dystrophy occurs when a different mutation in the same gene results in some dystrophin, but it's either not enough or it's poor in quality. Parent Project Muscular Dystrophy published a consensus statement for the care of persons with Duchenne and Becker muscular dystrophy during the COVID-19 pandemic. Givinostat (ITF2357) is an experimental treatment that Italfarmaco is developing to treat Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD). The diagnosis is confirmed by genetic testing or, rarely, testing a piece of muscle tissue. Becker muscular dystrophy is a genetic disease caused by a gene on the X chromosome that mothers carrying the gene can pass to their sons. It affects the same number of men and women. Access and mobility concerns in the community invariably touch upon the adjustment issues faced by individuals with a progressive disability. Abnormal but functional dystrophin may be produced, in contrast to the pathology in DMD, in which a frame-shift mutation essentially leads to failure to produce dystrophin. Becker Muscular Dystrophy (BMD) What is Becker muscular dystrophy? Becker muscular dystrophy (BMD) is one of nine types of muscular dystrophies, a group of genetic, degenerative diseases primarily affecting voluntary muscles. A child is more at risk for BMD if … In muscular dystrophy, the weakness is in the muscles. Becker muscular dystrophy (DIS-trah-fee), or BMD, is a genetic disease affecting different groups of muscles in the body. The heart comprises mostly muscle, and therefore it is affected by muscular dystrophy. The role of physical therapy services is to address the functional needs of the patient as the disease progresses. The disorder is passed down through families, which is inherited. Becker muscular dystrophy can cause cardiomyopathy, a weakening of the heart muscles, which, if unaddressed, can lead to heart failure and the need for a transplant. BMD is treated the same way, but studies on the impact of steroids are much more limited in the BMD patient population. BMD typically presents as a less severe form of muscle wasting than the similar Duchenne's muscular dystrophy (DMD) because people with BMD have reduced dystrophin, whereas people with DMD … Steroids are the mainstay of therapy for people with BMD.

But the disease rarely causes health problems until a child has muscle weakness in the hips and pelvis. Becker muscular dystrophy (BMD) is an X-linked recessive disorder due to mutation in the Dystrophin gene that results in progressive muscle degeneration and proximal muscle weakness. Over time, the muscles may become too tight and pull together painfully. 1990;26:271. Peverelli L, Testolin S, Villa L, et al.

Each son of a carrier mother has a 50:50 chance of being affected and each daughter has a 50:50 chance of being a carrier. The disease is named after German doctor Peter Emil Becker, who first described this variant of DMD in the 1950s. A reading frame or in-frame mutation hypothesis has been proposed to explain the abnormal translation of the dystrophin gene. BMD can present in several ways such as waddling gait, exercise related cramps with or without myoglobinuria. Causes include injury from trauma or repetitive strain injury, nerve damage or compression in the neck or upper back, or a blockage in the bloodstream.
