Can a girl get muscular dystrophy
Muscular dystrophy is a general name for a group of rare diseases that cause muscle weakness. It is caused by mutations in certain genes. There are more than 30 different types of muscular dystrophy and each affects certain muscles and varies in severity. The most common type, called Duchenne muscular dystrophy, usually begins between ages 2 to 5 and symptoms progress quickly.SEE VIDEO BY TOPIC: Muscular Dystrophy for USMLE

About Duchenne Muscular Dystrophy
Muscular dystrophy MD is a broad term that describes a genetic inherited disorder of the muscles. Muscular dystrophy causes the muscles in the body to become very weak. The muscles break down and are replaced with fatty deposits over time. Other health problems commonly associated with muscular dystrophy include the following:. The most common forms of muscular dystrophy are Duchenne muscular dystrophy DMD and Becker muscular dystrophy.
The two forms are very similar, but Becker muscular dystrophy is less severe than DMD. Girls are rarely affected by either of these two forms of muscular dystrophy. Duchenne muscular dystrophy is a genetic disease which means it is inherited. Our genes determine our traits, such as eye color and blood type. Genes are contained in the cells of our bodies on stick-like structures called chromosomes.
There are normally 46 chromosomes in each cell of our body, or 23 pairs. The first 22 pairs are shared in common between males and females, while the last pair determine gender and are called the sex chromosome pair: females have two X chromosomes, while males have one X and one Y chromosome.
Duchenne muscular dystrophy is caused by an X-linked recessive gene. Genes on the X chromosome can be recessive or dominant, and their expression in females and males is not the same because the genes on the Y chromosome do not exactly pair up with the genes on the X.
X-linked recessive genes are expressed in females only if there are two copies of the gene one on each X chromosome. However, for males there only needs to be one copy of an X-linked recessive gene in order for the trait or disorder to be expressed. For example, a woman can carry a recessive gene on one of the X chromosomes unknowingly, and pass it on to a son, who will express the trait or disease. Muscular dystrophy is usually diagnosed in children between 3 and 6 years of age.
Early signs of the illness include a delay in walking, difficulty rising from a sitting or lying position, and frequent falling, with weakness typically affecting the shoulder and pelvic muscle as one of the initial symptoms.
The following are the most common symptoms of muscular dystrophy. However, each child may experience symptoms differently. Symptoms may include:.
Children with Duchenne muscular dystrophy find it very hard to get up from a sitting or lying position on the floor. They first pull up to their hands and knees. The child walks his or her hands up their legs to brace themselves as they rise to a standing position. In addition, children with muscular dystrophy often have very large calves due to the large amounts of fatty deposits that are replacing muscle.
The symptoms of muscular dystrophy may resemble other conditions or medical problems. Always consult your child's doctor for a diagnosis. The diagnosis of muscular dystrophy is made with a physical examination and diagnostic testing by your child's physician. During the examination, your child's doctor obtains a complete prenatal and birth history of the child and asks if other family members are known to have muscular dystrophy.
Diagnostic tests for muscular dystrophy may include:. To date, there is no known treatment, medicine, or surgery that will cure muscular dystrophy, or stop the muscles from weakening. The goal of treatment is to prevent deformity and allow the child to function as independently as possible.
Since muscular dystrophy is a life-long condition that is not correctable, management includes focusing on preventing or minimizing deformities and maximizing the child's functional ability at home and in the community. Management of muscular dystrophy is either nonsurgical or surgical. Nonsurgical interventions may include:. Muscular dystrophy is a progressive condition that needs life-long management to prevent deformity and complications. Walking and sitting often becomes more difficult as the child grows.
Usually by the age of 12, the child needs a wheelchair because the leg muscles are too weak to work. Heart or lung problems often occur by the late teenage years or into the early 20s.

How is muscular dystrophy diagnosed? Diagnostic tests for muscular dystrophy may include: Blood tests.
These include genetic blood tests. Muscle biopsy. The primary test used to confirm diagnosis. A small sample of muscle tissue is taken and examined under a microscope. Electromyogram EMG. A test to check if the muscle weakness is a result of destruction of muscle tissue rather than nerve damage. A test that records the electrical activity of the heart, shows abnormal rhythms arrhythmias or dysrhythmias , and detects heart muscle damage.
Treatment for muscular dystrophy Specific treatment for muscular dystrophy will be determined by your child's doctor based on: Your child's age, overall health, and medical history The extent of the condition The type of condition Your child's tolerance for specific medications, procedures, or therapies Expectations for the course of the condition Your opinion or preference To date, there is no known treatment, medicine, or surgery that will cure muscular dystrophy, or stop the muscles from weakening.

Arizona Woman with Duchenne is a Rarity Among the Rare
Muscular dystrophies MD are common neuromuscular nerve and muscle disorders, characterised by loss of muscle strength and bulk. DMD is caused by a gene change or alteration, called a genetic mutation, in the dystrophin gene on the X chromosome. DMD can occur randomly in a family or be inherited. Females are not usually affected by the symptoms of DMD, but can be carriers of the condition and pass it on to their children. Some carriers experience mild symptoms such as muscle weakness or cramping.
D eb and Shawn Jenssen were used to frustration. Their kids had been turned away from studies. Doctors had questioned if they could really be showing signs of a disease even as it made it harder for them to walk. All of it helped explain why that brief moment in an Orlando hotel conference room caught their attention — why it felt like hope. The Jenssens were there for another conference on Duchenne muscular dystrophy.
Duchenne Muscular Dystrophy
Duchenne muscular dystrophy also called Duchenne MD or DMD is the most common form of muscular dystrophy , a genetic disorder that gradually makes the body's muscles weaker. Children with Duchenne MD also may have learning difficulties. Duchenne MD is progressive, meaning problems get worse with age. As kids with DMD become teens, muscle weakness throughout the body can lead to heart and breathing problems. Duchenne MD happens because of a lack of dystrophin dis-TRO-fin , a protein made by the muscle cells. In DMD, a variation or missing part of the dystrophin gene causes a loss of the dystrophin protein. This protein loss prevents the muscle fibers from working properly, leading to weakness. Duchenne MD affects boys more often than girls because the dystrophin gene is on the X chromosome. Boys have only one X chromosome and girls have two.
Three cases of manifesting female carriers in patients with Duchenne muscular dystrophy.
Duchenne muscular dystrophy usually affects males. However, females are also affected in rare instances. We investigated the clinical features of 3 female patients with dystrophinopathy diagnosed by clinical, pathological, and genetic studies at our neuromuscular disease clinic. The onset age of manifesting symptoms varied years. Muscle weakness grade varied as follows: patient 1 showed asymmetrical bilateral proximal upper and lower extremities weakness, patient 2 showed asymmetrical bilateral upper extremities weakness similar to scapulohumoral muscular dystrophy, and patient 3 had only bilateral asymmetric proximal lower extremities weakness.
Muscular dystrophy is a group of inherited diseases that damage and weaken your muscles over time. This damage and weakness is due to the lack of a protein called dystrophin, which is necessary for normal muscle function. The absence of this protein can cause problems with walking, swallowing, and muscle coordination.

Muscular dystrophy MD is a broad term that describes a genetic inherited disorder of the muscles. Muscular dystrophy causes the muscles in the body to become very weak. The muscles break down and are replaced with fatty deposits over time.
The reasoning is sound: A female has two X chromosomes to a male's one, so she has a built-in "backup" if anything should go wrong on either of her two Xs. She can be a "carrier" of an X-linked disease, because she can give a flawed X chromosome to her sons, who, having only one X, will likely develop an X-linked disorder. DMD is one of many X-linked diseases, such as two kinds of hemophilia including one that affected generations of European royalty and red-green color blindness. The gene for a muscle protein known as dystrophin is located on the X chromosome, and mutations in it were identified as the cause of DMD by MDA researchers in In boys with DMD, the lone X chromosome has only one dystrophin gene; if there's a mutation in that gene, the boys' muscles will lack dystrophin and slowly degenerate.
Pediatric Muscular Dystrophies
Duchenne muscular dystrophy DMD is a rapidly progressive form of muscular dystrophy caused by a mutation in the DMD gene. DMD is a rapidly progressive form of muscular dystrophy that occurs primarily in boys. It is caused by an alteration mutation in a gene, called the DMD gene that can be inherited in families in an X-linked recessive fashion, but it often occurs in people from families without a known family history of the condition. Individuals who have DMD have progressive loss of muscle function and weakness, which begins in the lower limbs. The DMD gene is the second largest gene to date, which encodes the muscle protein, dystrophin. Boys with Duchenne muscular dystrophy do not make the dystrophin protein in their muscles.
Muscular dystrophy MD is an inherited genetic disorder of the muscles. It is called a neuromuscular disease. There are several types. Becker muscular dystrophy BMD is a rare type. It has milder symptoms than Duchenne muscular dystrophy DMD , which is more common.
Duchenne muscular dystrophy
There are a number of Facebook groups focused on female carriers. Discussions and questions arise around why some female carriers of Duchenne have symptoms while others do not. Because Duchenne is primarily a diagnosis of boys, primary care providers pediatricians often do not consider it when they are trying to figure out why little girls are weak, have speech delays, or issues with balance.
They rallied around ‘our boys’ as they pushed for a Duchenne cure. Where did that leave girls?
Duchenne muscular dystrophy affects an estimated 1 in 3, male births. But Elizabeth Heller is an outlier even among her rare friends. The Chicago-born Heller, who relocated to Tempe, Arizona, three years ago, is one of only a handful of women with Duchenne in the United States. This is because the mutated gene responsible for Duchenne is located in the X chromosome.
Back to Muscular dystrophy. There are many different types of muscular dystrophy MD. Girls can occasionally be affected, although the condition tends to be milder. Children with Duchenne MD usually start to have noticeable symptoms between 1 and 3 years of age. The muscles around their pelvis and thighs tend to be affected first and often appear bulkier than normal.
