<prompt> Answer this question truthfullyWhat are the potential clinical presentations of McCune-Albright syndrome, and what hormonal imbalances may contribute to these symptoms?  <response>: <reason> McCune-Albright syndrome is a rare genetic disorder that can present with a range of symptoms, including precocious puberty and gigantism. Precocious puberty is characterized by the onset of puberty before the age of 8 in girls and 9 in boys, and may be due to excess LHFSH secretion. Gigantism is characterized by excessive growth and may be due to excess growth hormone secretion. Both of these hormonal imbalances can be caused by McCune-Albright syndrome, which is caused by a mutation in the GNAS1 gene. In addition to precocious puberty and gigantism, McCune-Albright syndrome can also cause bone deformities, skin pigmentation changes, and other endocrine abnormalities.
