Abstract: Part of a survivial motor neuron (SMN) gene-like DNA fragment has been identified .This DNA fragment was accidentally isolated from cDNA by RT–PCR using primers specific for the region between exon 3 and 6 of the SMN gene .This fragment was used as a probe to hybridize the mRNA from several tissues, but we have been unable to detect any transcript of this SMN-like gene in these tissues. Thus, we have inferred this SMN gene-like fragment was a genomic product contaminant that was amplified in the reaction . Sequencing analysis of this fragment , which contains several stop codons, revealed a 74.6% nucleotide homology with the SMN gene. From these results, we believe that this DNA fragment is not a mutated form of SMN gene . Rather , it is an SMN-like pseudogene ,which is variably present even in normal individuals.
我們利用RT–PCR方法分析SMN基因的表現,分析其產物偶然發現一段與SMN基因非常相似的產物,其DNA序列的分析結果顯示有74.6%的核?酸同質性,但其中含有幾個停止的密碼,我們又發現此基因片斷在各種組織並無表現,因此,我們認為它是一個SMN偽基因的片斷。此偽基因片斷並無intron,而且有些正常人並無此基因。
