Is muscular dystrophy common in boys?
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. So girls can almost always make working dystrophin using the dystrophin gene on their second X chromosome.
Why do boys get muscular dystrophy?
DMD generally affects boys because the dystrophin gene is on the X chromosome. Chromosomes are the parts of your cells that contain your genes. Boys only have one X chromosome. Girls have two X chromosomes, one from each parent.
How do you know if your child has muscular dystrophy?
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.
At what age does muscular dystrophy appear?
Onset usually occurs in the teenage years but can begin in childhood or as late as age 50. Congenital. This type affects boys and girls and is apparent at birth or before age 2. Some forms progress slowly and cause only mild disability, while others progress rapidly and cause severe impairment.
Does muscular dystrophy run in families?
In most cases, muscular dystrophy (MD) runs in families. It usually develops after inheriting a faulty gene from one or both parents. MD is caused by mutations (alterations) in the genes responsible for healthy muscle structure and function.
Can you test for muscular dystrophy during pregnancy?
Genetic testing can also be used for prenatal diagnosis. This is when a baby is diagnosed with MD before birth using tests carried out during pregnancy. You may be offered these tests if you’re pregnant and there’s a possibility that your unborn baby has MD.
Can you detect muscular dystrophy before birth?
Prenatal diagnosis. Genetic testing can also be used for prenatal diagnosis. This is when a baby is diagnosed with MD before birth using tests carried out during pregnancy. You may be offered these tests if you’re pregnant and there’s a possibility that your unborn baby has MD.
What is the worst type of muscular dystrophy?
Myotonic dystrophy is highly variable and often gets worse very slowly, with little change over long periods of time. However, it can become more severe as it’s passed down through the generations. Some people with myotonic dystrophy may never have a significant disability, although their heart rate will need to be monitored for abnormalities.
What are some facts about muscular dystrophy?

Is muscular dystrophy and multiple sclerosis the same thing?
Muscular dystrophy and multiple sclerosis are two similar diseases, but their causes are vastly different. Multiple sclerosis is an autoimmune disease that affects the nervous system, and muscular dystrophy is a genetic disorder that impacts muscle function.
