What is a common phenotype feature of individuals with Turner Syndrome?

Individuals with Turner Syndrome often present with short stature, which is one of the most recognizable phenotypic features of this condition. Turner Syndrome is a chromosomal disorder that affects females, typically characterized by the complete or partial absence of one of the X chromosomes. This genetic anomaly can lead to various developmental issues, including growth deficiencies. As a result, many girls with Turner Syndrome experience a significantly lower height compared to their peers, leading to short stature being a prominent physical characteristic.

In contrast, the other options listed—polydactyly, clenched hands, and echogenic bowel—are not typically associated with Turner Syndrome. Polydactyly refers to having extra fingers or toes and is commonly linked to other genetic disorders, while clenched hands can be seen in conditions like congenital syndromes such as Down syndrome. Echogenic bowel is often an ultrasound finding that can signify various conditions, including infections or genetic syndromes, but it is not a definitive characteristic of Turner Syndrome.

Thus, short stature stands out as the defining phenotypic feature in individuals with Turner Syndrome, making it the correct answer.
