Unfortunately, there are no great treatments for Duchenne or Becker muscular dystrophy.

DMD或BMD暂时没有好的治疗方法。

Since this is linked to the X chromosome, both Duchenne and Becker muscular dystrophy are called X-linked recessive.

由于发病与X染色体有关联，DMD和BMD被称为X连锁隐性遗传。

Now, the fact that both Duchenne and Becker muscular dystrophy result from mutations in the same dystrophin gene means that they are " allelic disorders, "

DMD和BMD都是由于同一抗肌萎缩蛋白基因突变引起的，意味着二者是“等位基因疾病”。

Within that group, dystrophinopathies are the most common, which includes Duchenne muscular dystrophy, or DMD, and Becker muscular dystrophy, both of which result from mutations in the dystrophin gene.

这些功能紊乱中，营养不良疾病是最常见的，包括Duchenne型肌营养不良（DMD）和Becker型肌营养不良（BMD）；这二者都是由抗肌萎缩蛋白基因突变导致的。

On the other hand, mutations that allow for a misshapen protein to form, like missense mutations, lead to Becker muscular dystrophy which is basically a milder form of Duchenne muscular dystrophy that presents later on, usually between age 10 to 20.

另一方面，突变（如错义突变）会导致畸形蛋白形成，引发BMD，病情比DMD较轻，发病年龄较晚，一般在10到20岁。
