**Core Concept**
CHARGE syndrome is a rare genetic disorder characterized by a combination of congenital anomalies. It is caused by mutations in the CHD7 gene, which is essential for normal embryonic development. The acronym CHARGE stands for Coloboma, Heart defects, Atresia of the choanae, Restricted growth and development, Genital hypoplasia, and Ear anomalies.

**Why the Correct Answer is Right**
CHARGE syndrome is a distinct clinical entity with a specific set of characteristics. The CHD7 gene plays a crucial role in the development of various organs and systems. Mutations in this gene lead to the characteristic features of CHARGE syndrome, including heart defects, choanal atresia, and ear anomalies. The syndrome is often associated with other developmental abnormalities, such as coloboma and genital hypoplasia.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not a characteristic feature of CHARGE syndrome.
* **Option B:** While some individuals with CHARGE syndrome may have intellectual disability, it is not a defining feature of the syndrome.
* **Option C:** This is not a recognized component of the CHARGE syndrome acronym.

**Clinical Pearl / High-Yield Fact**
CHARGE syndrome is often diagnosed through a combination of clinical evaluation and genetic testing. A high index of suspicion is essential, as the syndrome can be easily missed in its early stages.

**Correct Answer:** D. Genital hypoplasia.
