  • Publication number: 20230416823
    Abstract: The present invention chiefly aims to provide a new method of detecting or determining ApoE genetic polymorphism, that is rapid and less invasive to the subject. The present invention includes, for example, a method for detecting a genetic polymorphism of apolipoprotein E present in genomic DNA collected from a subject, comprising the following steps 1 to 3: 1. a step of preparing a specimen with DNA released from saliva; 2. a step of adding the followings to the specimen containing the DNA and then mixing: (1) a PCR enzyme, (2) a PCR primer pair for amplifying a nucleic acid fragment of the apolipoprotein E gene, and (3) a fluorescent labeled probe set which has oligonucleotides for detecting the genetic polymorphism of apolipoprotein E; and 3. a step of performing PCR, and measuring the fluorescence intensities according to the genetic polymorphism of apolipoprotein E from the PCR product.

  • Publication number: 20200190590
    Abstract: Provided is a method for predicting probability of ischemic stroke onset. A method for predicting a risk of ischemic stroke onset, the method comprising: a detection step of detecting presence or absence of a RNF213 p.R4810K gene variant in a sample derived from a test subject who does not develop ischemic stroke; and a determination step of determining whether a probability of ischemic stroke onset of the test subject is high or not, based on the presence or absence of the RNF213 p.R4810K gene variant in the detection step, and gender information of the test subject. A genetic marker for predicting a risk of ischemic stroke onset using gender information, comprising a RNF213 p.R4810K gene variant. A biomarker for predicting a risk of ischemic stroke onset using gender information, comprising a polypeptide encoded by a RNF213 p.R4810K gene variant.
