Study Notes
Klinefelter Syndrome Overview
- Klinefelter Syndrome is a genetic condition marked by an extra X chromosome in males, resulting in a 47,XXY chromosomal pattern.
- This condition can lead to various physical, developmental, and emotional symptoms in affected individuals.
Common Symptoms
- A common symptom is reduced testosterone levels, which can cause delayed or incomplete puberty, breast development, and infertility.
- Other symptoms may include taller stature, longer limbs, and less muscular body structure compared to peers.
Impact During Puberty
- Affected individuals may experience inadequate secondary sexual characteristics due to low testosterone production.
- There may also be difficulties in developing facial and body hair, as well as narrower shoulders and wider hips.
Chromosomal Pattern
- The typical chromosomal pattern for Klinefelter Syndrome is 47,XXY, although variations can occur, including the presence of more than one extra X chromosome (e.g., 48,XXXY).
Age of Diagnosis
- Klinefelter Syndrome is most commonly diagnosed in adolescents and young adults, typically during puberty when symptoms become more apparent.
- Early diagnosis can aid in managing symptoms and improving quality of life through appropriate medical interventions.
