Turner Syndrome vs. Klinefelter Syndrome: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 28, 2023
Turner syndrome is a chromosomal condition in females; Klinefelter syndrome is a chromosomal condition in males.
Key Differences
Turner syndrome is a genetic disorder affecting females, resulting from a missing or partially missing X chromosome. On the other hand, Klinefelter syndrome is a condition in males, caused by the presence of an extra X chromosome.
Individuals with Turner syndrome typically have a single X chromosome, symbolized as "45,X" or "45,X0". In contrast, individuals with Klinefelter syndrome have two X chromosomes and one Y chromosome, represented as "47,XXY".
Turner syndrome can lead to short stature, ovarian dysfunction, and heart defects. Meanwhile, Klinefelter syndrome can result in reduced testosterone, small testicles, and decreased body and facial hair.
While Turner syndrome is exclusively found in females and affects their development, Klinefelter syndrome affects males, influencing their physical and cognitive growth.
Both Turner syndrome and Klinefelter syndrome are non-heritable genetic conditions. Early diagnosis and intervention can help manage their symptoms and potential complications.
