Clinical Information

Turner syndrome, classified under ICD-10 code Q96.2, is a chromosomal disorder that primarily affects females and is characterized by the complete or partial absence of one of the two X chromosomes. This condition leads to a variety of clinical presentations, signs, symptoms, and patient characteristics that can significantly impact the individual's health and development.

Clinical Presentation

Karyotype Characteristics

The karyotype associated with Turner syndrome typically shows a 45,X configuration, indicating the absence of one X chromosome. However, in cases classified under Q96.2, the karyotype is 46,X with an abnormal sex chromosome, excluding iso (Xq) variations. This means that while there is one normal X chromosome, the second sex chromosome is abnormal, which can manifest in various ways depending on the specific chromosomal abnormalities present[2][4].

Common Signs and Symptoms

Individuals with Turner syndrome may exhibit a range of physical and developmental signs, including:

  • Short Stature: One of the most consistent features, with affected individuals often being significantly shorter than their peers due to growth hormone deficiencies[6].
  • Gonadal Dysgenesis: This refers to underdeveloped ovaries, leading to primary amenorrhea (absence of menstruation) and infertility[4][6].
  • Webbed Neck: A characteristic physical feature where the skin on the sides of the neck appears to be stretched or webbed[5].
  • Lymphedema: Swelling due to lymphatic fluid accumulation, often seen in the hands and feet at birth[6].
  • Cardiovascular Issues: Congenital heart defects, particularly coarctation of the aorta, are common in Turner syndrome[4][5].
  • Skeletal Abnormalities: These may include scoliosis, cubitus valgus (elbow deformity), and other bone-related issues[6].
  • Kidney Abnormalities: Some individuals may have structural kidney issues, which can lead to complications[4].

Additional Symptoms

Other symptoms may include:

  • Delayed Puberty: Due to ovarian insufficiency, many individuals do not undergo normal puberty without hormone replacement therapy[5].
  • Hearing Loss: There is an increased risk of conductive hearing loss due to ear abnormalities[6].
  • Cognitive and Learning Differences: While intelligence is typically normal, some individuals may experience specific learning disabilities, particularly in spatial reasoning and mathematics[4][5].

Patient Characteristics

Demographics

Turner syndrome affects approximately 1 in 2,500 live female births, making it one of the most common chromosomal disorders in females[6]. It can occur in any ethnic group and is not influenced by maternal age, although the risk of chromosomal abnormalities increases with maternal age.
