He has duchenne muscular dystrophy which is ultimately a fatal disease.

他患有杜氏肌营养不良症，这最终是一种致命的疾病。

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。

There's no equivalent to the " Duchenne smile." That's as far as I know.

没有什么可以与“杜兴微笑”相媲美。据我所知，情况就是这样。

What's interesting is about only one out of every ten people can fake a Duchenne smile.

只有十个人中有一个能够伪造杜甫深笑， 这是非常有趣的。

Editing the unhealthy cells of those suffering from genetic diseases such as Duchenne's muscular dystrophy and cystic fibrosis will alleviate their suffering.

编辑那些患有杜氏肌营养不良和囊性纤维化等遗传疾病的人的不健康细胞将减轻患者痛苦。

A real happiness smile, what's known as a Duchenne smile, after a neurophysiologist who studied it, involves moving the eyes.

一个真正的幸福微笑，也就是所谓的杜氏微笑，得名于一个研究过它的神经生理学家，它涉及到眼睛的运动。

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。
