Turner Syndrome (45,XO)

Turner Syndrome (45,XO) is a genetic condition that affects females and involves the loss of all or part of one of the two X chromosomes. This condition primarily impacts the reproductive system, leading to problems such as short stature and infertility due to underdeveloped ovaries. It can also affect the heart, kidneys, and cause distinctive physical features like a webbed neck and a broad chest. Many individuals with this syndrome have normal intelligence but may experience learning difficulties, especially with spatial concepts. Early diagnosis and management are important to address the various health issues associated with this condition.

Turner Syndrome (45,XO) is a chromosomal disorder characterized by complete or partial monosomy of the X chromosome in phenotypic females. The core pathology involves the absence of one X chromosome, resulting in gonadal dysgenesis and failure of normal ovarian development. This leads to primary amenorrhea, infertility, and short stature due to haploinsufficiency of genes involved in growth and sexual development. Common clinical features include lymphedema, webbed neck, coarctation of the aorta, and renal anomalies. The syndrome is caused by nondisjunction or structural abnormalities of the X chromosome during meiosis. It is clinically significant due to its multisystem involvement and the need for lifelong surveillance and management of associated complications.
