What is the official name of the REN gene?
The official name of this gene is “renin.”
REN is the gene's official symbol. The REN gene is also known by other names, listed below.

What is the normal function of the REN gene?
The REN gene provides instructions for making a protein called renin, which is produced in the kidneys. This protein is part of the renin-angiotensin system, which regulates blood pressure and the balance of fluids and salts in the body. In the first step of this process, renin converts a protein called angiotensinogen into angiotensin I. Through an additional step, angiotensin I is converted to angiotensin II. Angiotensin II causes blood vessels to narrow (constrict), which results in increased blood pressure. Angiotensin II also stimulates production of the hormone aldosterone, which triggers the absorption of water and salt by the kidneys. The increased amount of fluid in the body also increases blood pressure. Proper blood pressure during fetal growth, which delivers oxygen to the developing tissues, is required for normal development of the kidneys, particularly of structures called the proximal tubules, and other tissues. In addition, angiotensin II may play a more direct role in kidney development, perhaps by affecting growth factors involved in development of kidney structures.
How are changes in the REN gene related to health conditions?
Where is the REN gene located?
Cytogenetic Location: 1q32
