Abstract
A Spanish family with X linked dominant Charcot-Marie-Tooth (CMTX1) neuropathy was screened for point mutations in the connexin32 gene (GJ beta 1). The patients showed a C-T transition at position 552 which predicts arginine to tryptophan substitution at amino acid 164 (R164K). This mutation destroys an AciI restriction site at position 552 and creates a PflMI restriction site.
摘要
对一个患有X连锁显性遗传性腓骨肌萎缩症（CMTX1）的西班牙家族进行了连接蛋白32基因（GJβ1）点突变筛查。患者在552位出现了C-T转换，预测该位点的精氨酸被色氨酸替代（R164K）。此突变破坏了552位的AciI限制性酶切位点，并产生了一个PflMI限制性酶切位点。
