NR3C2

NR3C2 encodes the mineralocorticoid receptor, which responds to hormones such as aldosterone and helps regulate salt and fluid balance. It is distinct from the NR3C1 glucocorticoid receptor.

Mineralocorticoid signaling and salt balance

Mineralocorticoid signaling and salt balance

NR3C2 encodes the mineralocorticoid receptor, which responds to hormones such as aldosterone and helps regulate salt and fluid balance. It is distinct from the NR3C1 glucocorticoid receptor.

Putting the pieces together

Dr. Purser groups NR3C2 into the broader stress-response discussion. Its role also makes blood pressure, electrolyte results and relevant medicines important context. A wellness SNP is not evidence that the receptor is missing or that salt, potassium or hormone treatment should be changed.

A question to bring to your visit

Do blood pressure, electrolytes or medicines provide a clinical reason to investigate this pathway?
