An Overview Of Klinefelter And Turner’s Syndrome

During pregnancy, expectant parents might opt for a variety of non-invasive prenatal tests such as a prenatal paternity test or a test to determine the gender of an unborn child. While the NIPT procedure can tell the latter with utmost accuracy, there might be cases where the test results are inconclusive. One possible cause for this is sex chromosome aneuploidy or SCA, wherein the child has too many or too few sex chromosomes in some or all of the cells, creating patterns such as XO and XXY instead of the typical XX and XY patterns that are observed in females and males respectively. The two most common types of SCAs are Klinefelter Syndrome and Turner Syndrome. 

The nature of these syndromes will be discussed in detail below.

Klinefelter Syndrome

Klinefelter Syndrome is caused by the presence of the XXY chromosome instead of the XY chromosome. This condition only affects male children. There are no predetermined causes of Klinefelter Syndrome, as it occurs due to a random error in cell division during conception. 

Some common symptoms of this condition include the presence of enlarged breast tissue, also known as gynecomastia, weak bones, broad hips, small genitalia that may or may not be functional, delay in puberty, lack of hair growth on the face and body and much more. However, in most cases, the condition is not debilitating and with some hormone replacement therapy and counselling, the children suffering from Klinefelter Syndrome can lead fruitful lives. 

Turner Syndrome

Turner Syndrome is a condition that affects only female children who lack one X chromosome in their genetic makeup. It can be caused by a variety of reasons such as monosomy, which is an absence of the second X chromosome in all the cells, mosaicism, which can be defined as an absence of X chromosome in only some of the cells, or trace presence of Y chromosome. 

Unlike Klinefelter Syndrome, women and children suffering from this condition might need constant medical care as it can cause a few health complications. Some common symptoms include delay in growth and puberty, cardiac problems, infertility, irregular menstrual cycles, and can even lead to loss of vision, hearing and a bevy of autoimmune diseases. 

Ultimately, with a basic knowledge of these two syndromes, expectant parents can be better prepared to care for their children who might have these conditions.
