Leading clinicians review in depth the clinical and molecular aspects of the hormone resistance syndromes caused by receptor mutations. These mutations are involved in a large number of disorders, including dwarfism, Laron syndrome, pseudohypoparathyroidism, insulin resistance, resistance to thyroid hormone, glucocorticoid resistance, hereditary resistance to vitamin D, and estrogen resistance. Throughout, the books distinguished contributors not only summarize the clinical features of these and related disorders, but also illuminate their molecular bases. Hormone Resistance Syndromes provides an authoritative summary and standard reference for all those clinicians and researchers actively studying these mutations today and affords a unique opportunity to understand hormone action in normal physiology.
