What chromosomal anomaly is associated with Turner syndrome?

Turner syndrome is specifically characterized by the presence of a single X chromosome, leading to a chromosomal arrangement known as 45,X or X0. This condition occurs when one of the two X chromosomes typically found in females is missing or is partially missing. Individuals with Turner syndrome often exhibit various physical and medical challenges, including short stature, delayed puberty, and infertility, as well as potential heart and kidney issues.

In contrast, the chromosomal anomalies represented by other options do not correspond to Turner syndrome. For instance, XXY is associated with Klinefelter syndrome, while XXX denotes an additional X chromosome without the characteristic features of Turner syndrome. YY does not correspond to a viable human development as there are typically not two Y chromosomes in females, and it is not part of these syndromic presentations. Therefore, the chromosomal anomaly linked to Turner syndrome is unmistakably identified as X0.
