Endocrine gland
The adrenal glands are located above the kidneys in humans and in front of the kidneys in other animals. The adrenal glands produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. It controls the behaviour during crisis and emotional situations. It stimulates the heart and its conducting tissues and metabolic processes.
Absent adrenal gland
SF-1 plays a role in the development of adrenal gland. Single gene polymorphism involving SF-1 gene may have a role in adrenal gland agenesis. Various other factors have also been identified.
