This study intends to find out the pathogenic genes of bipolar disorder by collecting the two-phase family of Chinese Han population with the large sample using a family cohort study design, combined with the new generation of high-throughput sequencing technology and Genome-Wide Association Studies (GWAS), Proteomics, bioinformatics analysis, etc., which is expected to be clarified at the genetic level. The pathogenesis of bipolar disorder.

Full description
Bipolar disorder (BD) is a serious, complex, family-grafting mental illness. Studies have shown that genetic factors may be the dominant factor in the pathogenesis of bipolar disorder, thus, it is worth looking forward to getting started and clarifying the etiology of bipolar disorder from a genetic perspective. However, earlier genetic studies such as linkage analysis, genetic mutation detection (preferred candidate genes), and recent genetic studies (no need to presuppose candidate genes) such as Whole Genome Sequencing (WGS), whole genome GWAS and Whole-exome sequencing (WES) failed to identify any biogenic disorder gene or chromosomal region that plays a major role in, which may be related to the synergy of population heterogeneity, insufficient sample size or coordination effect caused by common mutations.
As a familial, highly heritable psychiatric disease, the literature suggests that the pathogenic genes of bipolar disorder may be directly derived from the intergenerational transmission of rare mutations in family members, and these rare variants are more likely to be predicated from the family. It has been found that the family has a higher frequency and is more susceptible to detecting susceptibility genes for bipolar disorder. Therefore, the family research design combined with WGS, GWAS and other advanced genetic research methods can reduce the unnecessary sample size, eliminate the confounding factors of the population, and more easily capture the potential genes of bipolar disorder.
However, at present, there are few reports of foreign bipolar disorder family and the results are not consistent. There is no research report on the large sample family of Chinese Han population in China. Therefore, it is necessary to expand the family sample size and combine with new genetic research methods in the Han population. explore. Therefore, this study intends to find out the pathogenic genes of bipolar disorder by collecting the two-phase family of Chinese Han population with the large sample using a family cohort study design, combined with the new generation of high-throughput sequencing technology and GWAS, Proteomics, bioinformatics analysis, etc., which is expected to be clarified at the genetic level.
