Familial Hypertension

Familial Hypertension includes a few rare genetic conditions that lead to early onset and treatment-resistant hypertension due to flaws in the body's sodium handling systems. Protheragen offers complete preclinical services focusing on the molecular mechanisms of inheritance in these disorders to accelerate the development of therapies for hypertension of renal origin.

Introduction to Familial Hypertension

The term refers to heightened (diagnostic) blood pressure levels that appear to cluster in the same blood relatives, which suggests a notable heritable factor is modulating the risk and expression of hypertension. While essential hypertension remains somewhat of a mystery, occurring in roughly 30-40% of the adult population (near 47% in the U.S.), having a genetic predisposition for hypertension, especially with a familial history of early onset (before 55-60 years). This genetic risk is due to a combination of shared familial lifestyles and environments and genetic variants that are known to modulate blood pressure. Hypertension in these individuals poses a heightened risk to grievous outcomes such as ischemic heart disease and renal disease which demonstrates the important need of research in this specific area.

Pathogenesis of Familial Hypertension

Familial hypertension is characterized by an interplay of environment and hereditary factors which disturb the regulation of blood pressure mechanisms. While more commonly the result of a combination of factors, sometimes familial hypertension can stem from a single genetic cause that offers insight into relevant mechanisms. The kidney remains the prime organ involved in hypertension management and its pressure-natriuresis mechanism, as well as hereditarily malfunctioning salt and water balance, is often at the center of familial hypertension.

Key factors of familial hypertension include the genetic variants of the renal tubular sodium exon which results in sodium retention, and sodium-dependent hypertension. Specific genetic susceptibilities can also lead toward an imbalance of the RAAS, increasing its vasoconstriction, salt, and water retention. Along with that is a genetic predisposition toward a higher tone of the sympathetic nervous system, peripheral resistance, and accelerated heart rate. Some genetic variants can lead toward the dysfunction of the vascular endothelium which results in the inappropriate narrowing of blood vessels, increased stiffness, and damage to the blood vessels. There is emerging evidence which suggests that certain genetic factors influencing the pathways of inflammation that leads toward the damage of blood vessels and hypertension.
