Klinefelter syndrome

Even though many women who have Turner have non-functioning ovaries and are infertile, their vagina and womb are totally normal.

Missing one copy of this gene likely causes short stature and skeletal abnormalities in women with Turner syndrome. This includes bicuspid aortic valve and coarctation narrowing of the aorta. They show some abnormal features such as enlarged breasts, underdeveloped body hair, and small testes and prostrate glands.

The natural history of aortic root dilatation is still unknown, but it is Turner and klinefelter syndrome to aortic dissection and rupture, which has a high mortality rate. Research shows a possible association between age at diagnosis and increased substance use and depressive symptoms.

They may also suffer from cardiovascular disease and other hormonal problems.

Turner syndrome

These symptoms are sometimes noticed at the time of puberty. The fetuses are often severely hydropic Figure 1. Whether aortic root diameters that are relatively large for body surface area but still well within normal limits imply a risk for progressive dilatation remains unproven. A tendency to develop high blood pressure so this should be checked regularly.

But in rare cases, a male is born with an extra X chromosome XXY. However, its relative risk is in comparison with the general population.

Testes, ovary absent or poorly developed.

Difference betweeen Klinefelter Syndrome and Turner Syndrome

Skeletal[ edit ] Normal skeletal development is inhibited due to a large variety of factors, mostly hormonal. A small percentage of females with Turner syndrome have a part of one X chromosome in a ring formation.

Additional chromosomal material can contribute to cardiac, neurological, orthopedic, and other anomalies.Still other types of genetic diseases include chromosome abnormalities (for example, Turner syndrome, and Klinefelter syndrome), and mitochondrial inheritance (for example, epilepsy and dementia).

High Blood Pressure Hypertension. Turner syndrome affects only females as the result of a missing or partially missing X chromosome, causing a variety of medical and developmental problems.

Klinefelter syndrome. Individuals with this syndromes are phenotypically males but with tendency towards femaleness. They show some abnormal features such as enlarged breasts, underdeveloped body hair, and small testes and prostrate glands.
