ConclusionThe ARIX gene polymorphisms, especially the nucleotide change of G153A may be one of genetic risk factors for concomitant exotropia.

结论ARIX基因多态性，尤其是G153 A核苷酸突变可能是共同性外斜视的遗传风险因子。

Their trouble with language had been caused by the change of a single nucleotide of dna-just one letter in the genetic sequence.

他们的语言问题仅仅是因为DNA中一个核苷酸发生了改变，也就是说基因序列中有一个字母被改写了。

A SNP is a variation in just one nucleotide of a genetic sequence; think of it as a spelling change affecting just one letter in an uncommonly long word.

一个SNP就是只在一个基因序列的一个核苷酸中发生的变异；就像一个拼写变化只影响一个罕见的长单词中的一个字母。
