Association between the C3F-gene and essential hypertension
Clinical Science (London, England : 1979)
|December 1, 1981
Summary
The C3F-gene is more frequent in essential hypertension patients, increasing risk by 1.90. This association is stronger in untreated individuals, suggesting immunogenetic factors in hypertension development.
Area of Science:
- Immunogenetics
- Cardiovascular Disease Research
Background:
- Essential hypertension is a complex condition with multifactorial etiology.
- The role of immunogenetic factors in hypertension pathogenesis requires further investigation.
Purpose of the Study:
- To investigate the association between the complement 3 (C3) phenotype distribution, specifically the C3F-gene, and essential hypertension.
- To determine the relative risk of essential hypertension associated with the C3F-gene.
Main Methods:
- Comparative analysis of C3 phenotype distribution in 112 essential hypertension patients and 316 normotensive controls.
- Calculation of relative risk for essential hypertension in C3F-positive individuals.
Main Results:
- A significantly increased frequency of the C3F-gene was observed in patients with essential hypertension (0.2637 vs 0.1721, P = 0.0031).
- The relative risk of essential hypertension for C3F-positive individuals was 1.90.
- The association was stronger in untreated patients (relative risk 3.89).
- A negative correlation was found between C3F-positivity and hypertensive disease severity (eye changes).
Conclusions:
- The C3F-gene is associated with an increased risk of essential hypertension.
- Immunogenetic factors, specifically related to complement C3, may play a role in the pathogenesis of essential hypertension.
- Further research is warranted to elucidate the mechanisms underlying this association.

01:18Hypertension and Regulation of Blood Pressure
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

01:30Coronary Artery Disease I: Introduction
Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
01:28Hypertension I: Introduction
Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...
01:29Hypertension II: Pathophysiology
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
01:30Hypertension III: Clinical Manifestations and Diagnostic Studies
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
