Method for estimating major depression coming on susceptibility

Abstract

The invention relates to the field of the association analysis between the gene-environmental interaction and the disease susceptibility, in particular to a method for judging the disease susceptibility of severe depression through detecting the associative action between a NET gene and negative life events. The method solves the problem that the disease susceptibility of the severe depression cannot be accurately judged yet in prior art through detecting the NET gene only or evaluating the negative life events only. First, the study object that is peripheral blood leukocyte DNA is extracted by a conventional phenol-chloroform method; the polymerase chain reaction and the direct sequencing DNA technique are adopted to detect the polymorphism of SNPs rs2242446 and rs5569 which are the NET gene; the genotype and the allele of examinees are determined; then the screening and the judgement of susceptible population are evaluated and performed through combining a life event scale so as to find that individuals are easier to be attacked by tristimania when suffering from the stimulus of certain life events, wherein, NET gene rs2242446 polymorphism basic groups of the individuals are C, and rs5569 polymorphism basic groups thereof are A.

Description

technical field [0001] The invention belongs to the field of correlation analysis between gene-environment interaction and disease susceptibility, and specifically relates to a method for judging the onset susceptibility of major depression by detecting the joint action of NET gene and negative life events. Background technique [0002] Major Depression (MD) is one of the most common mental disorders in humans, and its lifetime prevalence rate is 16.2% in the United States and 15% in China. It not only affects the individual's physical and mental health and social function, but also has a high risk of suicide. About 2 / 3 of depressed patients have suicidal ideation and behavior, and 10% to 15% of them commit suicide successfully. Not only that, but the recurrence rate of major depressive disorder is also very high, and it shows an upward trend with the increase of the number of illnesses. However, the clinical effective rate of existing antidepressants is only 60%-70%. Rece...
