METHOD FOR DETERMINING THE HUMAN GENOTYPE BY POLYMORPHISM IN THE CYTOCHROME P450 GENE CYP2D6*4 (1846G>A), RS3892097 Russian patent published in 2018 - IPC G01N33/58 C12Q1/68 

FIELD: medicine; biotechnology.

SUBSTANCE: invention relates to medicine, biology and biotechnology and is intended to determine the human genotype by polymorphism in the cytochrome P450 gene CYP2D6*4 (1846G>A) rs3892097. Pair of primers is used, fluorescently labeled allele-specific oligonucleotide probes, and a universal oligonucleotide labeled with a fluorescence quencher are used. Assignment of a sample to a homozygote or heterozygote for a given allele is evaluated by the shape of the DNA melting curves, namely by the maximum of the first derivative of fluorescence plots.

EFFECT: invention allows to conduct a study in a single tube, which reduces the cost of the study.
