Which of the following is NOT a clinical feature of Albright-Hereditary Osteodystrophy?

Albright-Hereditary Osteodystrophy (AHO) is characterized by a variety of physical and health features due to an endocrine dysfunction stemming from mutations affecting the GNAS gene. Among the clinical features associated with AHO are a round face, short stature, and some degree of intellectual disability, although the latter can be variable and is often described as mild.

The presence of hyperthyroidism is notably not a characteristic feature of Albright-Hereditary Osteodystrophy. Hyperthyroidism typically results from conditions like Graves' disease, which are unrelated to the genetic and endocrine abnormalities seen in AHO. Therefore, choosing hyperthyroidism as the option that is not a clinical feature aligns with the understanding that it does not pertain to the core symptoms and presentation of this specific disorder.

In summary, while AHO includes distinct features such as facial changes, growth impacts, and cognitive variations, it does not involve issues with thyroid function, making hyperthyroidism the correct choice in this context.
