Transcript of Turner Syndrome

Dominant or Recessive?
Autosomal or sex-linked?
Turner syndrome is neither dominant or recessive. This is because it is a chromosomal disease caused by nondisjunction. Nondisjunction is not inherited, although chromosome deletion may be inherited through some families. But this can be the cause of sveral genetic disorders.
Turner Sydrome is also sex-linked. Because it runs through the second X chromosome, a male cannot possibly obtain the disease.
Number of People Affected
Turner Syndrome affects 1 in every 2,500 girls. Although, 99% of them are miscarried. 15% of all miscarriages is due to Turner Syndrome.
What causes Turner Syndrome?
The chromosomal cause for Turner Syndrome is the failure of the second X chromosome to split from either the egg or sperm that is replicated. So a sperm or egg pairs up missing most or all of the X chromosome. Since a male only needs one X, they are not susceptible to the disease.
Symptoms of Turner Syndrome
If a girl with Turner Syndrome is to survive birth, they will have several bodily birth defects. These defects would include short stature, webbed neck, receding jaw, heart defects and swelling in the hands and feet. Turner Syndrome will cause a hormone deficiency in girls, causing them to not go through puberty fully. They will not receive all the traits that come along with puberty, which means they can not have children. They also may carry problems in understanding and logical reasoning.

Treatment for Turner Syndrome
Treatments would include hormone growth supplements to help with growth and functioning as well as estrogen therapy. Although, there is not much you can do for the pain of heart defects and body defects besides pain pills. The body cannot be surgically fixed in anyway.

What is Turner Syndrome?
Turner Syndrome is a chromosomal condition that occurs in the womb of the first trimester to females. Most baby girls do not survive the first trimester, and if they do, they obtain hormonal conditions.
