How can hormone deficiency or hormone receptor resistance cause congenital disorders?

Congenital disorders related to the endocrine system can arise from hormone deficiency or hormone receptor resistance, often stemming from genetic or developmental factors.1

Mechanisms of Endocrine Dysfunction

• Hormone Deficiency: This occurs when there is an inadequate supply of a hormone. It may be caused by incomplete formation of an endocrine gland during fetal development or inherited genetic mutations that result in a deficiency of enzymes required for hormone synthesis. For example, in congenital adrenal hyperplasia, mutations in genes encoding specific enzymes disrupt the production of hormones like cortisol.12
• Receptor Resistance: This condition involves a deficiency or dysfunction of hormone receptors on target organs. Even if hormone levels are sufficient, the body cannot respond appropriately because the target cells lack the necessary receptors to receive the hormonal signal, leading to reduced hormonal action.1
• External Factors: Congenital hypofunction can also be triggered by substances, such as certain drugs, that cross the placenta and block fetal hormone production or interfere with maternal hormone signaling.1

These disruptions are fundamental to the pathology of various congenital disorders, as hormones are essential for regulating growth, metabolism, and development.31
