The application discloses the application of the MT-2A
gene SNP site in the detection of susceptibility to heavy
metal poisoning. The SNP site is G>A at the 178th
nucleotide of the MT‑2A
gene, and the sequence of the MT‑2A
gene is shown in SEQ ID No.7. The G and A of the SNP loci are significantly different between the case group and the control group, wherein, G is a
cadmium poisoning susceptible
allele or a
cadmium poisoning high
risk allele, and A is a non-
cadmium poisoning susceptible
allele Genes or low-risk alleles for cadmium
toxicity. Therefore, by detecting the base type of this site, judging the
genotype of this site can be used to detect heavy
metal (such as cadmium) poisoning susceptibility or heavy
metal poisoning risk, screen patients with heavy
metal poisoning, identify or assist in the identification of heavy
metal poisoning susceptibility genes, Detection of single
nucleotide polymorphisms associated with heavy
metal toxicity or
metabolism. The applications and products provided by the invention are of great value in the identification of susceptible groups to heavy
metal poisoning, thereby reasonably preventing heavy metal poisoning.
