Charcot-Marie-Tooth神经病是一组遗传异质性的周围神经系统疾病。据报道,Mfn2基因突变是2A型Charcot-Marie-Tooth病的主要原因。采用单链构象多态(SSCP)技术对临床诊断为腓骨肌萎缩症2型的患者进行筛查。所有在SSCP分析中出现条带移动的DNA样本都从基因组DNA中扩增并进行循环测序。我们分析了73名临床诊断为CMT-2的无关患者。总体而言,在6名患者中发现了新的突变。C.380G>T(G127V)、c.1128G>A(M376I)、c.1040A>T(E347V)、c.1403G>A(R468H)、c.2113G>A(V705I)和c.2258_2259insT(L753fs)。我们证实了Mfn2基因突变在2型Charcot-Marie-Tooth病发病机制中的重要作用。
Charcot-Marie-Tooth neuropathies are a group of genetically heterogeneous diseases of the peripheral nervous system. Mutations in the MFN2 gene have been reported as the primary cause of Charcot-Marie-Tooth disease type 2A. Patients with the clinical diagnosis of Charcot-Marie-Tooth type 2 were screened using single strand conformation polymorphism (SSCP). All DNA samples showing band shifts in the SSCP analysis were amplified from genomic DNA and cycle sequenced. We analyzed a total of 73 unrelated patients with a clinical diagnosis of CMT 2. Overall, novel mutations were detected in 6 patients. c.380G>T (G127V), c.1128G>A (M376I), c.1040A>T (E347V), c.1403G>A (R468H), c.2113G>A (V705I), and c.2258_2259insT (L753fs). We confirmed a significant role of mutations in MFN2 in the pathogenesis of Charcot-Marie-Tooth disease type 2.
