Abstract

The invention provides a kit used for detecting human MTHFR and MTRR gene polymorphism, and a detection method thereof. The kit is used for avoiding defects and insufficient in conventional gene polymorphism detection technology. A primer and a probe used for detecting MTHFR and MTRR gene polymorphism are provided; the primer and the probe can be used for detecting MTHFR gene 677C>T and 1298A>C site and MTRR gene 66A>G site polymorphism, and are high in sensitivity and specificity. The kit can be used for rapid, high efficiency, and accurate detection of human MTHFR gene 677C>T and 1298A>C site and MTRR gene 66A>G site polymorphism. The invention also provides the detection method used for detecting human MTHFR and MTRR gene polymorphism using the kit. The detection method is convenient inoperation, high in sensitivity and specificity, wide in suitable machine type range, real and reliable in detection results, and is convenient for popularization.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a kit for detecting human MTHFR and MTRR gene polymorphisms and a detection method thereof. Background technique [0002] Folic acid is a glutamic acid containing a pteridine ring. It is a B-family water-soluble vitamin that cannot be synthesized by the human body and needs to be ingested through food. It is called vitamin M, vitamin Bc or vitamin B9. It is H.K.Mitchell , 1941) extracted and purified from spinach, so it was named folic acid. Folic acid is an important substance in cell growth, differentiation, repair and host defense, and it is an indispensable nutrient in the process of embryonic development. Folic acid deficiency or metabolic disorders can lead to interference in DNA biosynthesis and in vivo methylation levels, leading to disease. Folic acid is an indispensable nutrient for fetal growth and development. Folic acid deficiency in pregnant women may lead to low birth...
