some of which are able to compensate for loss ofSMN1but many of which do not. Spinal muscular atrophy can be divided into four types, with an onset ranging from just after birth through to adulthood, and dependent on the compensatory expression fromSMN2[19]. The symptoms includemuscle weaknes...

脊髓性肌肉萎缩症(Spinal muscle atrophy):是由SMN1基因突变导致的一类疾病,其中SMN2是SMN1的同源基因,与SMN1有共同的编码区。SMN1的7号外显子变化则会导致外显子跳跃,产生没有7号外显子的缩短型SMN2蛋白,这种缩短型蛋白易降解,没有实质功能。通过寡核苷酸(ASO)nusinersen与靶标结合,阻止其7号外显子被剪切,产生...
