鉴定引起罕⾒神经退⾏性疾病和神经肌⾁疾病的新基因突变

历经超过四年的研究,陈浩然教授及其团队发现了⼀种新的基因突变,该突变可导致脊髓小脑萎缩症 (SCA)的出现。 陈教授等通过对患者亲属及其儿女的基因测序和⽣物信息学分析,将导致患者发⽣遗传性SCA基因突变的可能性,确定在含有CCDC88C的卷曲螺旋结构领域内 ,这种基因突变的携带者将会出现SCA40的病症。

这种新发现的SCA分型,被 “⼈类基因组基因命名委员会” 确认,并命名为 “SCA40  ” 型。 相关硏究发表在著名的 “Journal of Medical Genetics” 期刊上。 该研究促进了來⾃波兰的相同病例的鉴定进程。 鉴定新基因突变,能够扩阔⼈类对SCA潜在原因的学术理解,并为患者提供了基因鉴定和咨询服务的机会,同时它还阐明了SCA的潜在治疗方法。
