Is there a genotype for high blood pressure?

Genotype for HBP. Yes in rare cases there are specific genes that cause high blood pressure. Other clues to genes are: Is there high blood pressure in your family? Do you have a twin with high blood pressure? Are of you African Descent especially African American. But we do not know the genes for most causes of high blood pressure. All genes today appear to involve salt metabolism as does much garden variety HTN.
Probably. There is not one specific genotype. However, hypertension or high blood pressure is known to be at least partially genetic with 70-80% of patients with hypertension having some family history of hypertension. The genes discovered to date only account for a small amount of the variation in blood pressure.
Maybe. Commonest cause for high blood pressure is age and family history. It is possible there are genotypes that are predisposed however that is not how we physicians approach HTN at this time.
