| 摘 要： | 本文研究了8个独立来源的中国汉族人Leber氏病家系的患者,其中在4个家系的患者中找到了这种突变。这种转换突变使NADH脱氢酶第4个亚单位(ND_4)的第340位编码子的精氨酸转变为组氨酸,并使SfaNI酶的切割位点消失,因此可提供一种简单的诊断方法。

| Abstract: | Leber's hereditary optic neuropathy is a maternally inherited disease. The mitochondrial DNA mutation was correlated with this disease. In our report, eight patients form independent Chinese families with this disease were analysed. The mutation was found in four families. This replacement mutation converted a arginine to a histidine at con-don 340 in the 4th gene subunit of NADH deny-drogenase and eleminated a sfa NI site. The finding provided a simple diagnostic test for this disease. |
