Turner Syndrome and Klinefelter Syndrome are two genetic conditions resulting from chromosomal abnormalities, but they differ significantly in terms of their causes, symptoms, diagnosis, and treatment. Understanding these differences is essential for medical professionals, patients, and caregivers.
Aspect | Turner Syndrome | Klinefelter Syndrome |
---|---|---|
Genetics | Missing one X chromosome in females (45,X). | Extra X chromosome in males (47,XXY). |
Affected Gender | Females only. | Males only. |
Symptoms | - Short stature - Webbed neck - Lack of secondary sexual characteristics - Infertility - Heart and kidney abnormalities | - Tall stature - Small testes and infertility - Gynecomastia - Reduced facial/body hair - Learning difficulties |
Diagnosis | Identified in childhood or adolescence through karyotype testing and physical examination. | Often diagnosed in adolescence or adulthood due to fertility issues or hormonal imbalances. |
Treatment | - Growth hormone therapy - Estrogen replacement therapy - Monitoring of heart and kidney health | - Testosterone replacement therapy - Fertility treatments - Support for developmental challenges |
Fertility | Most individuals are infertile due to ovarian failure. | Infertility is common but may be addressed with advanced reproductive technologies. |
Physical Traits | Short stature, webbed neck, broad chest. | Tall stature, reduced muscle mass, gynecomastia. |
Prevalence | Affects 1 in 2,500 live female births. | Affects 1 in 500 to 1,000 live male births. |
Genetic Cause | Missing X chromosome (monosomy X). |

Women with Turner syndrome do not have normal ovarian growth. They do not usually produce all the physical changes that occur in adolescence and do not reproduce as adults.
No, it is not inherited. When this condition results in monosomy X, chromosomal abnormalities occur as a random event during the formation of reproductive cells in the affected human parent.
It can have a detrimental effect on the growth of the testicles leading to smaller testicles which can lead to lower testosterone production. Klinefelter syndrome can also cause weight loss, muscle mass, enlargement of the breast tissue, and facial hair.
Turner syndrome affects females with a missing or incomplete X chromosome, while Klinefelter syndrome affects males with an extra X chromosome.
Down syndrome involves an extra copy of chromosome 21, leading to intellectual disability and physical traits; Turner syndrome affects females with a missing X chromosome, causing developmental issues; Klinefelter syndrome affects males with an extra X chromosome, resulting in hypogonadism and infertility.
Klinefelter syndrome and XXY syndrome refer to the same condition where males have an extra X chromosome, leading to similar symptoms.
