Problems solved by technology

However, the previous genetic diagnosis was based on the Sanger sequencing method, which was costly, time-consuming, and complicated to operate, and was not suitable for clinical complex diseases caused by polygenic diseases, so it was powerless to treat hereditary vascular diseases

Embodiment 2

[0127] The primer pool of the present invention contains 103 genetic vascular disease-causing genes newly discovered by the inventor, as shown in Table 1 above. The newly discovered 103 genetic vascular disease-causing genes come from the research accumulation and family investigation of the inventors over the years. The inventor first searched through the KEGG signaling pathway and the homologous gene library among the known causative genes of hereditary vascular diseases to find the homologous genes of the known causative genes and the key genes on the same pathogenic pathway. Then, targeted high-throughput sequencing of candidate disease-causing genes was carried out in the large-scale case sample library of Chinese yellow-race patients accumulated over the years, and bioinformatics analysis was carried out to screen and find disease-causing mutations. Cases with pathogenic mutations were screened for follow-up and further family analysis, and the entire family of the patie...
