Primer set for detecting EGFR exon 21L858R gene polymorphism and use thereof

摘要

The invention provides a primer set for detecting a polymorphism in EGFR exon 21 1 L858R. The primer set has a P1 oligonucleotide and a P2 oligonucleotide and can perform amplification by using a region including the 172792nd base of SEQ ID NO: 1 as a template. As a base that is complementary to the 172792nd base of SEQ ID NO: 1, the P1 oligonucleotide has cytosine and the P2 oligonucleotide has adenine. The melting temperature of the P1 oligonucleotide is higher than the melting temperature of the P2 oligonucleotide, and/or the P1 oligonucleotide is one or more bases longer than the P2 oligonucleotide. The invention further provides a polymorphism detection primer, a polymorphism detection method using the primer set, a method of evaluating a EGFR tyrosine kinase inhibitor using the primer set, a primer used in the polymorphism detection method, and a kit including the primer set.
