Substitution and insertion in all strains si gene, the homogeneity of nucleotide and the deduced amino acids of s1 gene with 17 alien and domestic references strains were equally less than 80 %
S1基因除與qx的親緣關系較近外，與其它參考株的同源率均低於80 ，可能為一株國內流行性的變異株。 -
All the subjects were genotyped by pcr - rflp ( polymerase chain reaction - restriction fragment length polymorphism ) at polymorphic sac i site inside the exon 7 of the ahsg gene. this polymorphism involves a nucleotide substitution of c to g at the middle nucleotide of the codon at amino acid position 238 resulting in the replacement of threonine ( acc ) with serine ( agc )
所有的樣本通過聚合酶鏈式反應?限制性片段長度多態性方法（ pcr - rflp ）對ahsg基因的第7個外顯子內的sac多態性位點進行基因分型，該多態性位點為238號氨基酸密碼子中間的堿基c到g的替換，使蘇氨酸（ thr ， acc ）變為絲氨酸（ ser ， agc ） 。
