[Abstract]:Genome-wide association analysis (GWAS) and genomic exon sequencing are effective methods for locating disease-related genes. The main content of this thesis is to identify the susceptible genes of high myopia in Chinese population by the whole genome association analysis of high myopia and to screen the pathogenetic genes of the identical twins with different phenotypes of transposition of the great arteries by using the whole genome exon sequencing. High myopia refers to extreme myopia whose diopter is less than -6.00D or axial length is larger than 26mm. Although genetic factors play an important role in the development of high myopia, its susceptibility genes are not clear. In order to localize high myopia susceptibility genes in Chinese population, a genomic association analysis based on DNA mixed pool (DNA pooling) was carried out. First of all, in 476 patients with high myopia and 275 healthy controls, 19 tagged SNP in the MIR100HG and BLID gene regions were classified and analyzed by association analysis. The contribution of high myopia susceptibility genes located in Japanese population to susceptibility of Chinese population was excluded (all the SNP association results were significant higher than 0. 05), which suggested that Chinese population had their own specific genetic susceptibility. On the basis of this, 504 patients with high myopia and 276 healthy controls were analyzed for the whole genome association based on ENA pooling, and the association results were verified by individual typing. Finally, 9 significant gene regions associated with the disease were obtained. The rs10889602 on intron of PDE4B gene was identified as a candidate susceptibility site by functional analysis of related regions (pooling p1. 38 脳 10 ~ (-6), individual typing p0. 0198). Further repeated validation of this locus was performed in a total of 1606 patients from two different cohorts and 1509 controls. Finally, all the results were integrated and concluded that rs10889602 was associated with high myopia susceptibility in Chinese population (pmeta=3.72 脳 10-3). Inhibition of PDE4B gene function can induce myopia phenotype in guinea pigs. Transposition of great arteries is a cyanotic congenital heart disease, the pathogenesis of which is still unclear. In order to verify the role of genetic factors in the pathogenesis of transposition of the great arteries, a pair of identical twins with one disease and one normal were sequenced. A total of 49 mutation sites with differences between twins were obtained by high throughput sequencing, all of which were confirmed by mass spectrometry typing. At the same time, insertion deletion analysis and copy number variation analysis also found no confirmed differences. Further analysis revealed that both twins had missense mutations (G1437R) that affect protein function in the NOTCH1 gene that regulates asymmetric development. This gene has been reported to be a pathogenic gene for tetralogy of Fallot and aortic valve stenosis. Although the contribution of somatic mutation to the differential phenotypes of twins has not been confirmed, the results suggest that genetic factors play an important role in the transposition of the great arteries.
