Pituitary dwarfism is caused by a combined pituitary hormone deficiency. The effects include underdeveloped kidneys (and often renal failure), underactive thyroid glands, and sterility. The side effects are often noticed in the first few months as short legs, long body, a short jaw, bulging eyes, and skin disorders including baldness and bacterial skin infections. Age of symptoms onset apparent at 8-16 weeks. Forms of this disease can also be non-genetic.
