**Core Concept**
Turner syndrome is a genetic disorder in females resulting from the absence or abnormality of one X chromosome. This condition affects approximately 1 in 2,500 live-born females and is characterized by short stature, gonadal dysgenesis, and various other physical and developmental anomalies.

**Why the Correct Answer is Right**
Turner syndrome is associated with a range of clinical features, including:
- Short stature due to growth hormone deficiency or estrogen deficiency
- Gonadal dysgenesis, leading to ovarian failure and infertility
- Cardiovascular anomalies, such as bicuspid aortic valve and coarctation of the aorta
- Developmental delays and learning disabilities
- Physical features, including a webbed neck, low-set ears, and a broad chest

**Why Each Wrong Option is Incorrect**
**Option A:** **Stature normal** - Turner syndrome is characterized by short stature, so this option is incorrect.
**Option B:** **Gonadal dysgenesis** - Gonadal dysgenesis is a hallmark of Turner syndrome, making this option incorrect.
**Option C:** **Hypothyroidism** - While thyroid disorders can occur in Turner syndrome, they are not a universal feature. However, this option is less commonly seen compared to the other options.

**Clinical Pearl / High-Yield Fact**
Turner syndrome often presents with a wide range of systemic complications, including cardiovascular and renal anomalies. A high index of suspicion is required for early diagnosis and management.

**Correct Answer:** D.
