摘要:
The present invention provides a primer composition for amplifying a gene region having various variations in a target gene comprising: a first primer group comprising at least one primer specific to at least one template including a genotype-analyzable sequence of a genetically variant base sequence subjected to be analyzed in the target gene; and a second primer group comprising at least one primer designed by selecting one primer having the greatest number of shared bases from the primers of the first primer group and by using the selected primer as a reference, the primer of the second primer group binding specifically to the template or binding complementarily to the template with allowing mismatch of up to three successive bases or 1 to 2 bases in the vicinity of the 3′ end of the template.
