Kit for detecting genetic susceptibility of gestational diabetes mellitus

Abstract

The invention relates to a kit for detecting genetic susceptibility of gestational diabetes mellitus. The kit comprises a specific primer pair and a specific fluorescent probe pair which simultaneously detect the rs290487 SNP locus on TCF7L2 gene and the rs10830963 SNP locus on MTNR1B gene, Taq enzyme, dNTP mixed solution, an MgCl2 solution, a fluorescent quantitative PCR reaction buffer solutionand deionized water. The invention has the beneficial effects that: the genotypes of the rs290487 SNP locus on the TCF7L2 gene and the rs10830963 SNP locus on the MTNR1B gene are simultaneously detected for the first time, and the polymorphism of the two loci and dietary factors have interaction. Comprehensive evaluation indicates that the incidence risk of the gestational diabetes can be effectively predicted, and therefore accurate nutrition intervention or other treatment measures can be carried out on high-risk groups of the gestational diabetes before pregnancy as soon as possible.

Description

technical field [0001] The invention belongs to the fields of molecular biology and medicine, and in particular relates to a kit for detecting genetic susceptibility of gestational diabetes. Background technique [0002] Gestational diabetes mellitus (GDM) is abnormal glucose tolerance that occurs or is discovered for the first time during pregnancy and is one of the most common pregnancy complications. The incidence of gestational diabetes worldwide is increasing year by year with the increase in the incidence of overweight and obesity. In 2018, the prevalence of gestational diabetes in Chinese pregnant women was reported as high as 14.8%. With the change of my country's birth policy and the increase of advanced maternal age, the risk of gestational diabetes in pregnant women in my country will further increase. Abnormal blood sugar during pregnancy will increase the risk of pregnancy complications such as gestational hypertension, preeclampsia, premature delivery, and po...

Problems solved by technology

[0006] Although there are studies on the risk association between polymorphic sites of TCF7L2 gene and MTNR1B gene and GDM in the prior art, they are only conducted on polymorphic sites of a single gene, which are used to detect GDM separately. The sensitivity of genetic susceptibility is not high, and there is a lack of kits that can be used to detect genetic susceptibility to GDM in the prior art, and it is impossible to screen out high-risk groups of GDM susceptibility in time, so it is impossible to take preventive measures for GDM in advance
