[Susceptible genes of essential hypertension].
Essential hypertension (EH) is a complex multifactorial disorder with genetic and environmental factors contributing to its prevalence. The genetic features have been revealed from the significant familial aggregation and the consistency among twins. Therefore, identification of EH susceptibility genes will be helpful to understand the pathophysiology of the disease, identify populations with potential risks of developing the disease, and select antihypertensive drugs. The present article introduces the search strategies of EH susceptibility genes and some genetic variants related to EH; meanwhile, it tries to analyze the difficulties and the role for samples in identifying susceptibility genes to EH.
