研究价值 小脑共济失调是一种常染色体显性遗传的神经系统疾病,疾病临床常 表现为运动失调。本研究发现了小脑共济失调家族SCA23亚型新的致病基 因TGλ6。该基因的发现,对今后阐明小脑共济失调发病机制、遗传诊断 和新药研发具有重要的科学和应用价值。 ●方法与结果 对患有小脑共济失调的同一家系4个患者进行了全外显子组测序(平均 测序深度65.1×),在每个患者的外显子区域平均检测到约5800个潜在影 响基因功能的变异,包括NS(非同义突变)、SS(剪切位点突变)和 InDel(插入缺失突变),其中包含了大量的罕见变异。 筛选流程( bioinformatics application): 1)过滤掉同义突变等不影响基因功能的突变,只保留非同义突变、剪切位 点突变、插入缺失等影响基因功能的突变; 2)过滤掉公共遗传突变数据库( dbsnP等)正常人携带的常见突变、已发表 的正常对照个体的突变; 3)根据软件对突变进行功能预测,获得对功能有影响的候选基因和突变位 点 4)最后在所有患病个体的候选基因和突变位点集合中取交集

1) 研究人员选择了来自三个独立家系的四名米勒综合症(Miller syndrome; 常染色体隐性遗传单基因病)患者,进行外显子测序; 2) 通过与公共SNP数据库和8个来自HapMap的个体外显子数据相比较,4个 患者都同时含有2个先前未知的变异,这2个变异同时位于一个候选基因 DHODH上,该基因编码一个嘧啶从头合成途径中的关键酶蛋白; 3) 进一步在其它3个米勒综合症的家系中进行验证,发现患者的DHODH基 因上同样存在这个突变
