**Core Concept**
Albright syndrome, also known as McCune-Albright syndrome, is a rare genetic disorder characterized by a triad of fibrous dysplasia, café-au-lait skin spots, and precocious puberty. This condition is caused by mutations in the GNAS gene, which encodes the stimulatory G-alpha subunit of G-proteins.

**Why the Correct Answer is Right**
The GNAS gene plays a crucial role in regulating cAMP signaling pathways, which are involved in various cellular processes, including hormone secretion and cell growth. In Albright syndrome, the mutated GNAS gene leads to constitutive activation of cAMP signaling, resulting in the development of fibrous dysplasia, café-au-lait skin spots, and precocious puberty. This is due to the abnormal activation of various G-protein coupled receptors, including those involved in hormone secretion, such as gonadotropin-releasing hormone (GnRH) receptors.

**Option A:** This option is not specified, so it cannot be evaluated.
**Option B:** This option is not specified, so it cannot be evaluated.
**Option C:** This option is not specified, so it cannot be evaluated.

**Clinical Pearl / High-Yield Fact**
Albright syndrome is a classic example of a genetic disorder that affects multiple organ systems, including the skeletal, skin, and endocrine systems. It is essential to recognize the characteristic triad of this condition to make an accurate diagnosis.
