我们报告了一个新的错义突变(Gly 12 Ala)在铜/锌超氧化物歧化酶(SOD 1)基因外显子1在67岁的患者与家族性ALS(FALS)。临床过程显示出异常缓慢的进展。突变的SOD 1的酶活性是正常的80%。在分子水平上,Gly 12 Ala突变发生在活性位点以外的区域,并可能导致蛋白质结构的局部变形应变。
We report a new missense mutation (Gly12Ala) in exon 1 of the Cu/Zn superoxide dismutase (SOD1) gene in a 67-year-old patient with familial ALS (FALS). The clinical course showed an unusually slow progression. The enzymatic activity of the mutated SOD1 was 80% of normal. At the molecular level, the Gly12Ala mutation occurs in a region outside the active site and may lead to local distortion strain in the protein structure.
