Turner Syndrome and Klinefelter Syndrome are genetic disorders, caused by the variations in the number of sex chromosomes.
The Turner syndrome is mainly caused in 1 out of 2000 live births of a female baby. This syndrome is mainly caused due to the partial or complete absence of one X or sex chromosomes. Turner syndrome is also known as monosomy of the X chromosome. Turner syndrome leads to various developmental problems and people with this syndrome are at risk of many diseases.
Klinefelter syndrome is caused when a male baby is born with more than required or extra X chromosomes. This syndrome is found in 1 out of 1000 males. Klinefelter syndrome results in the formation of sperm or the egg and people with this syndrome are prone to tremors, osteoporosis and autoimmune disorders.

Let’s learn about the differences between Turner Syndrome and Klinefelter Syndrome
Turner Syndrome and Klinefelter Syndrome – Differences
|This syndrome is caused by the lack of sex chromosome (XO instead of XX).||This syndrome is caused by the presence of an extra sex chromosome (XXY instead of XY).|
|Monosomy of sex chromosome (2n-1), here only one X chromosome, is present in females.||The trisomy of sex chromosome (2n+1), here one extra X chromosome- XXY, are present in males.|
|1 in 2500 phenotypic females.||1 in 1100 phenotypic males.|
|Lymphedema, underweight and swelling or thickness of the neck.||Enlarged breasts, undeveloped penis and testicles.|
|Are absent||Are present and are atrophied|
|Undeveloped breast, absence of menstrual cycles, presence of vagina, vulva, uterus and sterility.||Presence of penis, vas deferens and seminal vesicles, but are inactive due to their undeveloped or smaller size.|
|Women with a webbed neck, short stature, poor or undeveloped breast, degenerated ovaries and rudimentary sexual characteristics.||Men with enlarged breasts|
|There is no cure for Turner syndrome. It is commonly treated with replacement therapy including estrogen and growth hormones.||Fertility treatment.|
Removal of excess breast tissue.
Hormonal Replacement Therapy.
