Q: Which of the following conditions is characterized by webbing of the neck, short stature, increased carrying angle, low posterior hairline, primary amenorrhea, and short fourth metacarpal?

Turner syndrome. ***Turner syndrome*** - Characterized by **webbing of the neck**, **short stature**, and **primary amenorrhea**, which are classic features of Turner syndrome [1][2]. - The presence of a **short fourth metacarpal** is also a specific skeletal manifestation associated with this condition. - **Short stature** in Turner syndrome is specifically explained by haploinsufficiency of the SHOX gene [1]. *Noonan syndrome* - Presents with features like **short stature** and **cardiac anomalies**, but lacks the specific manifestations of neck webbing and primary amenorrhea. - Typically associated with facial dysmorphisms, such as **widely spaced eyes** and a **distinctive appearance** which are not mentioned here. *Klinefelter syndrome* - Characterized by **47,XXY** karyotype leading to **gynecomastia** and **testicular atrophy**, rather than symptoms like webbed neck or short stature. - Men with this syndrome usually display **delayed or incomplete puberty**, not primary amenorrhea. *Cri-du-chat syndrome* - Primarily associated with a **distinctive high-pitched cry** and developmental delays, rather than physical traits like webbed neck or short fourth metacarpal. - Symptoms are more related to **chromosomal deletion** and do not include amenorrhea or features typical of Turner syndrome. **References:** [1] Kumar V, Abbas AK, et al..
