What are key characteristics of Turner syndrome?

Turner syndrome is a chromosomal condition that affects females, typically characterized by a partial or complete absence of one of the X chromosomes. The key features of Turner syndrome include short stature, which is evident from an early age and often leads to a final adult height significantly below that of the general population. A prominent feature is the presence of primary gonadal dysgenesis, which means that the individual's ovaries are either absent or non-functional, leading to infertility. Additionally, individuals with Turner syndrome often lack secondary sexual characteristics due to the absence of viable ovaries, resulting in underdeveloped reproductive organs and a lack of breast development during puberty.

Even though the option correctly includes short stature and the absence of ovaries, it highlights the significant lack of secondary sex characteristics, which is a hallmark of this condition. This reflects the fundamental impact of the disorder on growth and sexual development, distinguishing it from other conditions or syndromes that may present different sets of characteristics.
