In this report, the frequency of the G-->A transition polymorphism at nucleotide 5557 in exon 39 of the coding sequence of the gene mutated in ataxia-telangiectasia (ATM) was analysed. The frequency of the A and G alleles was estimated in the general population at 0. 15 and 0.85, respectively. This polymorphism can be identified by single-strand conformation polymorphism (SSCP) and by a simple and rapid Dde I digestion after polymerase chain reaction (PCR)-mediated site directed mutagenesis (PSDM).
在本报告中,分析了共济失调毛细血管扩张症(ATM)相关基因突变的编码序列第39外显子中核苷酸5557处G→A转换多态性的频率。在普通人群中,A和G等位基因的频率估计分别为0.15和0.85。这种多态性可以通过单链构象多态性(SSCP)以及聚合酶链反应(PCR)介导的定点诱变(PSDM)后简单快速的Dde I酶切来鉴定。
