Which disease is missing a chromosome?

Published in Genetic Disorder 2 mins read

Turner syndrome is a disease where a chromosome is missing.

Understanding Turner Syndrome

Turner syndrome is a genetic condition that affects only females. It occurs when one of the X chromosomes is missing or partially missing. This missing or incomplete chromosome leads to several health and developmental issues.

How Does it Happen?

  • Females typically have two X chromosomes (XX).
  • In Turner syndrome, one of these X chromosomes is either missing entirely (monosomy X) or is structurally abnormal.
  • This chromosomal abnormality can happen randomly during the formation of reproductive cells (eggs or sperm) or during early fetal development.

Effects of Turner Syndrome

The absence or abnormality of the X chromosome can lead to various problems:

  • Short stature: Individuals with Turner syndrome are usually shorter than average.
  • Ovarian insufficiency: The ovaries do not develop properly, leading to reduced hormone production and infertility.
  • Heart defects: Various heart problems can occur.
  • Other developmental issues: such as kidney problems, hearing issues and other challenges.

Diagnosis and Management

  • Turner syndrome is often diagnosed during infancy, childhood, or adolescence based on physical signs or during prenatal testing.
  • Early diagnosis is critical for managing health complications.
  • Treatment can include growth hormone therapy to increase height and hormone replacement to help with puberty.
  • Ongoing monitoring and support can help manage health conditions and optimize quality of life.
