Abstract:
At present, genome-wide association study on coronary heart disease (CHD) has been carried out in several major medical research centers worldwide. Most studies of CHD susceptibility loci or regions focused on chromosome 1, 3, 9, 11 and 16, while studies on chromosome 8 are rare. To the best of our knowledge, the genome study on chromosome 8 about CHD in Chinese Han population has never been reported before. We aimed to identify CHD susceptibility loci or regions in the Chinese Han population. First, two separated DNA pooling samples were prepared from 156 CHD cases and 1000 normal controls. Then, a total of 13 microsatellite markers at an interval of 10 cM on chromosome 8 were selected for genetic scanning. Finally, the difference of allele frequency at each locus between two pooled samples was analyzed by Chi-square test. Significant differences were found between cases and controls at D8S264(8p23.3-p23.2) and D8S285(8q12.1) (both P<0.05). Therefore, 8p23.3-p23.2 and 8q12.1 are possible to be associated with CHD and further study is needed to screen susceptible genes around these regions.
