NR5A1 : nuclear receptor subfamily 5 group A member 1

Understanding the NR5A1 Gene: A Key Player in Development and Hormones

Description

The NR5A1 gene holds the blueprint for the steroidogenic factor 1 (SF-1), a remarkable protein that acts as a gatekeeper for gene activity. Like a conductor of a symphony, SF-1 orchestrates the action of specific genes involved in the development and function of the gonads (ovaries and testes) and the adrenal glands, vital organs perched atop each kidney.

Associated Diseases

Mutations in the NR5A1 gene can lead to a spectrum of disorders, including:

• Congenital adrenal hyperplasia (CAH): Affects the production of adrenal hormones, leading to ambiguous genitalia, salt-wasting, and hypertension.
• 46,XY disorders of sex development (DSD): Disrupts the development of male genitalia, causing a range of symptoms including cryptorchidism (undescended testes) and short stature.
• Adrenal insufficiency: Affects the adrenal glands‘ ability to produce hormones, resulting in fatigue, muscle weakness, and weight loss.

Did you Know ?

Approximately 1 in 10,000 newborns is affected by disorders associated with NR5A1 gene mutations, highlighting the gene‘s crucial role in development.
