<p>The present invention is to provide a method for identifying a polymorphism. The method includes performing a nucleic acid chain extension reaction and identifying the polymorphism of the nucleic acid contained in the test nucleic acid sample. The extension reaction is conducted with use of a nucleic acid in a test nucleic acid sample as a template, a type I detection primer which hybridizes with a region including the polymorphic site of a nucleic acid whose polymorphic site nucleotide sequence consisting of a first nucleotide sequence, and a polymerase. The reaction is conducted with the presence of an inhibitory oligonucleotide, which hybridizes with the type I detection primer. The region of the type I detection primer to hybridize with the inhibitory oligonucleotide is located on the 5′side of the polymorphism detection site of the type I detection primer to hybridize with the polymorphic site.</p> |
