波兰华沙医科大学组织学和胚胎学系的cieyńska A近日在PLoS One杂志发表了一篇文章,题目为"Processing of OPA1 with a novel N-terminal mutation in patients with autosomal dominant optic atrophy: Escape from nonsense-mediated decay" ,他们发现了一种新型致病性OPA1突变,并确定它位于突变转录本不易发生NMD活化的区域。

常染色体显性视力萎缩(ADOA)是最常见的遗传性视神经病变。在大多数患者中,它是由OPA1突变引起的,并且经常检测到提早终止密码子(PTC)的插入。含有提早终止密码子(PTC)的转录本可能被无义介导的mRNA降解复合物(NMD)降解。但是OPA1突变对无义介导的mRNA降解复合物(NMD)的活化作用知之甚少。

在这发表的文章里,作者将遗传连锁分析和DNA测序的方法结合,在两个波兰家族中,确定了一个新的c.91C> T OPA1突变,其中这个位置上具有推测的早期终止密码子(Q31 *)。在mRNA水平上,他们发现突变携带者与非携带者之间的OPA1转录本的量没有显着差异。特异等位基因定量分析显示,有大量的OPA1突变体转录本存在。

他们的研究确定了一种新型致病性OPA1突变,并发现它位于转录本不易发生NMD活化的区域。他们的研究表明,细胞如何处理突变的基因具有重要的重要。这启示研究者通过了解遗传疾病的分子机制,可以促进创新治疗方法的发展。
