fragile x造句
例句与造句
- the screnning and prenatal gene dignosis for fragile x syndrome using pfu dna
综合征的筛查和产前基因诊断 - fxs is mainly caused by a kind of dynamic mutation, the expansion of a cgg repeat located in the 5'- untranslated region ( 5'- utr ) of the fmr1 ( fragile x mental retardation ) gene
该综合症由患者细胞中可见xq27.3的脆性位点fraxa而得名。绝大多数脆性x综合征患者的发病是由于fmr1基因5端非翻译区的三核苷酸cgg重复的不稳定扩增所致。 - fragile x syndrome ( fxs ) is the most common form of inherited mental retardation after down syndrome . it affects approximately 1 in 4000 males and 1 in 8000 females in the general population
脆性x综合征(fragilexsyndrome，fxs)是导致遗传性智力低下的主要原因之一，发病率仅次于先天愚型，在男性中的发病率约为1/4000，在女性中发病率约为1/8000。 - to detect the patients and carriers of the fragile x syndrome, various analytic methods could be used . one is cytogenetic diagnosis to observe the expression of the fragile site fraxa located at xq27.3
对脆x综合征的诊断，可以通过细胞遗传学方法观察分析x染色体相应脆性位点的表达情况，或是通过southern印迹杂交的方法直接分析cgg重复的扩增突变。 - the absence of the fmr1 gene product, fragile x mental retardation protein ( fmrp ), is believed to be responsible for the typical physical and mental characteristics of the fragile x syndrome . alleles with between 43 and 200 cgg repeats are called permutation . they are generally unmethylated with normal transcript and protein level, but are extremely unstable during transmission to next generation
带有前突变(n=43200)的个体其fmr1基因通常不会甲基化，可以正常转录和翻译产生fmrp，故没有临床表型出现，但是，在向下一代传递的过程中却是非常不稳定的，会从前突变扩增成为全突变。 - It's difficult to find fragile x in a sentence. 用fragile x造句挺难的
