儿童期发作的扭转性肌张力障碍(DYT 1)是一种罕见的遗传性运动障碍,通常由TOR 1A基因(ΔE,p.Glu303del)中的杂合GAG缺失(c.907-909)引起。torsin蛋白的神经功能和ΔE突变的发病机制尚不清楚。之前,我们已经从DYT 1患者成纤维细胞产生了hiPSC系。本研究对GAG缺失进行了遗传校正,获得了两个等基因对照系。这些hiPSC细胞系含有野生型TOR 1A序列,表现出正常的干细胞形态和核型,表达多能性标记,并分化为三胚层,为DYT 1的研究提供了宝贵的资源。
Childhood-onset torsin dystonia (DYT1) is a rare hereditary movement disorder and usually caused by a heterozygous GAG deletion (c.907–909) in the TOR1A gene (ΔE, p.Glu303del). The neuronal functions of torsin proteins and the pathogenesis of ΔE mutation are not clear. Previously, we have generated a hiPSC line from DYT1 patient fibroblast cells. In this study, we genetically corrected GAG deletion and obtained two isogenic control lines. These hiPSC lines contain the wild-type TOR1A sequence, showed the normal stem cell morphology and karyotype, expressed pluripotency markers, and differentiated into three germ layers, providing a valuable resource in DYT1 research.
