The invention discloses a specific primer and liquid chip for detecting polymorphism of a DPYD (dihydropyrimidine dehydrogenase) gene. The liquid chip mainly comprises ASPE (allele specific primer extension) primers, microspheres and amplification primers, wherein each ASPE primer is formed by tag sequences at the 5' terminal and specific primer sequences which are arranged at the 3' terminal and aim at the mutation site of the target gene; the specific primer sequences are SEQ ID NO.7 and SEQ ID NO.8 aiming at the G55A site, SEQ ID NO.9 and SEQ ID NO.10 aiming at the G141A site and / or SEQ ID NO.11 and SEQ ID NO.12 aiming at the G134T site; and the microspheres are enveloped by anti-tag sequences. The detecting liquid chip provided by the invention has the advantages that the consistency of the detection result and the sequencing method is as high as 100%, thus parallel detection of wild types and mutant types of a plurality of mutation sites is achieved.

The invention discloses a single-nucleotide polymorphism (SNP) detection specific primer of the CYP2C19 gene and a liquid phase chip. The liquid phase chip contains an ASPE primer composed of a tag sequence on the 5'-end and specific primers on the 3'-end which aims at the target genetic mutation, microspheres covered by the anti-tag sequence and an amplification primer, wherein the specific primers contain SEQ ID NO.25 and SEQ ID NO.26, SEQ ID NO.27 and SEQ ID NO.28 aiming at the C194T SNP site, SEQ ID NO.29 and SEQ ID NO.30, SEQ ID NO.31 and SEQ ID NO.32, SEQ ID NO.33 and SEQ ID NO.34, SEQID NO.35 and SEQ ID NO.36, SEQ ID NO.37 and SEQ ID NO.38, SEQ ID NO.39 and SEQ ID NO.40, SEQ ID NO.41 and SEQ ID NO.42, SEQ ID NO.43 and SEQ IDNO.44, SEQ ID NO.45 and SEQ ID NO.46, and / or SEQ ID NO.47 and SEQ ID NO.48. The coincidence rate of the detection result of the SNP detection liquid phase chip of the CYP2C 19 gene and the detection result adopting a sequencing method is up to 100%.

The invention provides a CYP2D6 gene mutation detection liquid-phase chip which comprises ASPE (Allele Specific Primer Extension) primers aiming at CYP2D6 C2850T and CYP2D6Deletion mutational sites, three microballoons respectively enveloped with a specific anti-tag sequence and amplification primers aiming at the CYP2D6C2850T and the CYP2D6 Deletion mutational sites.
