Spinal muscular atrophy type 3 (SMA3), or Kugelberg-Welander disease, is a relatively mild form of spinal muscular atrophy characterized by proximal muscle weakness and hypotonia caused by the degeneration of the lower motor neurons in the spinal cord and the brainstem nuclei. The onset of ...
SMN蛋白表达不足将导致脊髓前角运动神经元变性,继而造成肌肉神经源性肌萎缩,罹患脊髓性肌萎缩(Spinal Muscular Atrophy, SMA),是中国人最常见的常染色体隐性遗传的神经肌肉病。中国人群1174对夫妇中既有1对有生育患儿风险,风险值为1/4。95%的SMA患者是由SMN1基因第7外显子的纯合缺失所致。 临床表现 SMA患者临床主...
Spinal Muscular Atrophy(SMA),即脊髓性肌萎缩,是一种罕见且严重的遗传性神经肌肉退行性疾病。以下是对该疾病的详细
Spinal muscular atrophy (SMA) most often affects babies and children and makes it hard for them to use their muscles. When your child has SMA, there's a breakdown of the nerve cells in the brain and spinal cord. The brain stops sending messages that control muscle movement. When that happ...
Some children with Spinal Muscular Atrophy (SMA) can walk on their own with arm and balance support from a rolling walker. Walkers come in anterior (support bars in front) or posterior (support in back) styles. Your therapist will help you pick out a walker and teach your child how to ...

脊髓性肌肉萎缩症(SMA) 脊髓性肌肉萎缩症是一种由运动神经元退化引起的疾病,导致从脊髓到达肌肉系统的信号不足。该病是仅次于地中海贫血症的第二大常见遗传病。 脊髓性肌萎缩症的类型 脊髓性肌萎缩症可以影响任何年龄段的人群,从新生儿到成年人都有可能患病,但在婴儿期出现的症状往往更为严重。这种疾病可分为以下...
The Report Covers Global Spinal Muscular Atrophy (SMA) Market Analysis and is segmented by Type (Type I, Type II, Type III, and Type IV), Procedure (Gene Replacement Therapy and Drug Therapy), Route of Administration (Oral and Intrathecal), and Geography (North America, Europe, Asia-Pacific...
SMA I型在出生后2～3个月出现症状,婴儿会突然丧失肢体运动能力,发病急,进展快。常见表现为双腿关节屈曲,两腿外展,膝关节屈曲如蛙腿状。重者哭声小,吞咽因难,因肋间肌麻痹而呈腹式呼吸。一般在出生时就表现为严重的肌张力低的婴儿,极少生存超过一年。而6个月后出现肌无力的婴儿,进展较为缓慢,有些甚至可以有暂时...
脊髓性肌萎缩(Spinal Muscular Atrophy,SMA)是一种基因突变导致脊髓前角细胞变性引起肌无力和肌萎缩等临床症状的一组疾病。根据疾病严重程度及发病年龄,1992年在欧洲神经肌肉疾病中心召开的SAM国际研讨会将其分为4个类型(Ⅰ、Ⅱ、Ⅲ、Ⅳ)。据统计...
