Sitting atop each kidney and measuring only around two centimeters long, the adrenal glands are tiny but mighty. These glands produce steroid hormones, including those involved in stress response, blood pressure maintenance, and fertility. When their development goes awry, it can cause a life-threatening condition called primary adrenal insufficiency, also known as Addison’s disease. Many of the genetics involved in this and other adrenal gland disorders remain unknown.
