Question

Are hypertension and coronary heart diseases polygenic?

Answer 1

Polygenic disease:

1. Polygenic disease is a type of genetic disorder caused by more than one gene.
2. Various independent genes or polymorphic interacting genes result in polygenic diseases.
3. Both hypertension and coronary heart diseases are polygenic diseases.

Hypertension:

1. Hypertension is a medical condition in which the blood pressure is higher than the normal (120/80 mm Hg).
2. It leads to heart diseases, brain damage, and kidney failure.

Coronary heart disease:

1. In coronary heart disease (atherosclerosis), the lumen of arteries becomes narrower due to the deposition of fatty compounds and cholesterol.
2. It weakens heart muscles and may lead to heart attacks.
