A mutation in either a hormone or its receptor might affect the physiological system that it normally regulates by either blocking hormone effect or creating a completely different effect.
Hormones can be called chemical messengers which coordinate distinct functions in the body. Many glands, organs and tissues produce and release hormones, many of which constitute the endocrine system.
A hormone will only act on a part of the body if it fits i.e. if the cells in the target tissue have receptors which can receive the message of the hormone. Given that hormones carry instructions in their structure, mutations alter their structures by changing nucleic acid sequences which blocks hormone function.
