The mild end of the spectrum includes the phenotypes of asymptomatic increase in serum concentration of creatine phosphokinase (CK) and muscle cramps with myoglobinuria. The severe end of the spectrum includes progressive muscle diseases that are classified as Duchenne/Becker muscular dystrophy when skeletal muscle is primarily affected and as DMD-associated DCM when the heart is primarily affected. Duchenne muscular dystrophy (DMD) usually presents in early childhood with delayed motor milestones including delays in walking independently and standing up from a supine position. Proximal weakness causes a waddling gait and difficulty climbing stairs, running, jumping, and standing up from a squatting position. DMD is rapidly progressive, with affected children being wheelchair dependent by age 12 years. Cardiomyopathy occurs in almost all individuals with DMD after age 18 years. Few survive beyond the third decade, with respiratory complications and progressive cardiomyopathy being common causes of death. Becker muscular dystrophy (BMD) is characterized by later-onset skeletal muscle weakness. With improved diagnostic techniques, it has been recognized that the mild end of the spectrum includes men with onset of symptoms after age 30 years who remain ambulatory even into their 60s. Despite the milder skeletal muscle involvement, heart failure from DCM is a common cause of morbidity and the most common cause of death in BMD. Mean age of death is in the mid-40s. DMD-associated DCM is characterized by left ventricular dilatation and congestive heart failure. Females heterozygous for a DMD pathogenic variant are at increased risk for DCM." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln"><div class="excerpt">Excerpted from the <i>GeneReview: </i><a href="/books/NBK1119" target="_blank">Dystrophinopathies</a></div><div>The dystrophinopathies cover a spectrum of X-linked muscle disease ranging from mild to severe that includes Duchenne muscular dystrophy, Becker muscular dystrophy, and DMD-associated dilated cardiomyopathy (DCM). The mild end of the spectrum includes the phenotypes of asymptomatic increase in serum concentration of creatine phosphokinase (CK) and muscle cramps with myoglobinuria. The severe end of the spectrum includes progressive muscle diseases that are classified as Duchenne/Becker muscular dystrophy when skeletal muscle is primarily affected and as DMD-associated DCM when the heart is primarily affected. Duchenne muscular dystrophy (DMD) usually presents in early childhood with delayed motor milestones including delays in walking independently and standing up from a supine position. Proximal weakness causes a waddling gait and difficulty climbing stairs, running, jumping, and standing up from a squatting position. DMD is rapidly progressive, with affected children being wheelchair dependent by age 12 years. Cardiomyopathy occurs in almost all individuals with DMD after age 18 years. Few survive beyond the third decade, with respiratory complications and progressive cardiomyopathy being common causes of death. Becker muscular dystrophy (BMD) is characterized by later-onset skeletal muscle weakness. With improved diagnostic techniques, it has been recognized that the mild end of the spectrum includes men with onset of symptoms after age 30 years who remain ambulatory even into their 60s. Despite the milder skeletal muscle involvement, heart failure from DCM is a common cause of morbidity and the most common cause of death in BMD. Mean age of death is in the mid-40s. DMD-associated DCM is characterized by left ventricular dilatation and congestive heart failure. Females heterozygous for a DMD pathogenic variant are at increased risk for DCM. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK1119#dbmd.Summary" target="NBK1119">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1119#dbmd.GeneReview_Scope" target="NBK1119">GeneReview Scope</a>  |  <a class="medgenPMinfo" href="/books/NBK1119#dbmd.Diagnosis" target="NBK1119">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1119#dbmd.Clinical_Characteristics" target="NBK1119">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1119#dbmd.Genetically_Related_Allelic_Disorde" target="NBK1119">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1119#dbmd.Differential_Diagnosis" target="NBK1119">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1119#dbmd.Management" target="NBK1119">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1119#dbmd.Genetic_Counseling" target="NBK1119">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1119#dbmd.Resources" target="NBK1119">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1119#dbmd.Molecular_Genetics" target="NBK1119">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1119#dbmd.Chapter_Notes" target="NBK1119">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1119#dbmd.References" target="NBK1119">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />The muscular dystrophy that carries the Becker eponym is similar to Duchenne muscular dystrophy in the distribution of muscle wasting and weakness, which is mainly proximal, but the course is more benign, with age of onset around 12 years; some patients have no symptoms until much later in life. Loss of ambulation also varies from adolescence onward, with death usually in the fourth or fifth decade. In some cases, as in Duchenne muscular dystrophy, a degree of mental impairment is present (Emery, 2002).&#13;
As in DMD, about 5 to 10% of female carriers of this X-linked disorder show muscle weakness, and frequently enlarged calves--so-called manifesting heterozygotes. Such weakness is often asymmetric; it can develop in childhood or not become evident until adult life, and can be slowly progressive or remain static. Because weakness is essentially proximal, differentiation from limb-girdle muscular dystrophy is essential for genetic counseling. In both DMD and BMD, female carriers may develop dilated cardiomyopathy in the absence of apparent weakness (Grain et al., 2001).  <a target="_blank" href="http://www.omim.org/entry/300376">http://www.omim.org/entry/300376</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />Both the Duchenne and Becker forms of muscular dystrophy are associated with a heart condition called cardiomyopathy. This form of heart disease weakens the cardiac muscle, preventing the heart from pumping blood efficiently. In both Duchenne and Becker muscular dystrophy, cardiomyopathy typically begins in adolescence. Later, the heart muscle becomes enlarged, and the heart problems develop into a condition known as dilated cardiomyopathy. Signs and symptoms of dilated cardiomyopathy can include an irregular heartbeat (arrhythmia), shortness of breath, extreme tiredness (fatigue), and swelling of the legs and feet. These heart problems worsen rapidly and become life-threatening in most cases. Males with Duchenne muscular dystrophy typically live into their twenties, while males with Becker muscular dystrophy can survive into their forties or beyond.<br /><br />Duchenne and Becker muscular dystrophies have similar signs and symptoms and are caused by different mutations in the same gene. The two conditions differ in their severity, age of onset, and rate of progression. In boys with Duchenne muscular dystrophy, muscle weakness tends to appear in early childhood and worsen rapidly. Affected children may have delayed motor skills, such as sitting, standing, and walking. They are usually wheelchair-dependent by adolescence. The signs and symptoms of Becker muscular dystrophy are usually milder and more varied. In most cases, muscle weakness becomes apparent later in childhood or in adolescence and worsens at a much slower rate.<br /><br />A related condition called X-linked dilated cardiomyopathy is a form of heart disease caused by mutations in the same gene as Duchenne and Becker muscular dystrophy, and it is sometimes classified as subclinical Becker muscular dystrophy. People with X-linked dilated cardiomyopathy typically do not have any skeletal muscle weakness or wasting, although they may have subtle changes in their skeletal muscle cells that are detectable through laboratory testing.<br /><br />Muscular dystrophies are a group of genetic conditions characterized by progressive muscle weakness and wasting (atrophy). The Duchenne and Becker types of muscular dystrophy are two related conditions that primarily affect skeletal muscles, which are used for movement, and heart (cardiac) muscle. These forms of muscular dystrophy occur almost exclusively in males.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/duchenne-and-becker-muscular-dystrophy">https://medlineplus.gov/genetics/condition/duchenne-and-becker-muscular-dystrophy</a></div></div>
