45,X (monosomy X)

45,X, also known as Turner syndrome or monosomy X, is a genetic condition where an individual, typically female, has only one X chromosome instead of two sex chromosomes. This results in a total of 45 chromosomes instead of the usual 46. Individuals with Turner syndrome may experience a range of symptoms, including short stature, delayed puberty, and potential health issues like heart and kidney problems. Treatment options vary and can include hormone therapy and regular medical care. The condition is not inherited but occurs due to a random error during cell division in early development.
