Genetic Foundations of Adrenal Insufficiency
Adrenal insufficiency is a serious endocrine disorder characterized by the inability of the adrenal glands to produce adequate amounts of essential hormones, particularly cortisol and, in many cases, aldosterone. While autoimmune disease is the leading cause of adrenal insufficiency in adults, genetic defects play a major role in pediatric and congenital forms of the disease. In children, up to 80% of primary adrenal insufficiency (PAI) cases are linked to inherited genetic abnormalities. These genetic disorders affect adrenal function through several major mechanisms: disruption of steroid hormone synthesis, abnormal adrenal gland development, immune-mediated destruction of adrenal tissue, or metabolic disorders that progressively damage the adrenal cortex. Advances in molecular genetics have significantly improved the understanding of these conditions, enabling earlier diagnosis, targeted management, and genetic counseling.
