Question:
What is genetic abmormality Turner's Syndrome?



Replies:
Hi Brian

Turner Syndrome is a chromosomal condition that results from the total or partial absence of one of the two X chromosones normally found in women. It occours in 1 of every 2.000-2.500 females born. It is not associated with environmental or other external factors, and no real causes have been found until now seeming to be a random occurrence. The main consequences are short stature and infertility, but can also occur heart, kidney and tyroid health problems.

Absolutely there is no relation with mental retardation and it is recommendad that children and women with Turner Syndrome led complete normal life. Even there not a cure, up to now, there are procedures that can be taken to help with the symptoms as application of growth hormones, althrough that must be done only under medical recommendation and control.

You can find all the informations and help to deal with that condition at:

Otherwise referred to as the Monosomy X syndrome, it occurs in 1 out of every 5000 births. The person appears to be female, however she only carries one X chromosome and does not mature sexually and is sterile as a rule. Normal females are (XX) and these people ar (X0). They usually have normal intelligence, but are shorter in stature to normal females.

Turner syndrome is caused by nondisjunction, which is when a pair of chromosomes separate during meiosis. specifically the 23rd pair or the sex chromosomes doesn't separate. This causes one gamete to have too many chromosomes and another to have too few. In turner syndrome, the child inherits one X chromosome from one parent, and no sex chromosome from the other which makes it a girl who is X0 instead of XX. Girls with Turner tend to be immature sexually (ie, they look sexually immature) and are sterile.
