2   Turner syndrome is a disorder caused by the loss of genetic material from one of the sex chromosomes.  Turner syndrome (TS) is a chromosomal condition that describes girls and women with common features that are caused by complete or partial absence of the second sex chromosome.  Named after Dr. Henry Turner  He was one of the first to describe its features in the 1930s What is it?

4   Can only occur in females  1 out of every 2,500 female births  Result of problems with the chromosomes Important info.

5  Most girls are born with two X chromosomes Females with TS are missing one. This causes for many unusual body features in the females body. What exactly is the problem?

6   Short stature  a "webbed" neck (extra folds of skin extending from the tops of the shoulders to the sides of the neck)  a low hairline at the back of the neck  drooping of the eyelids  differently shaped ears that are set lower on the sides of the head than usual  abnormal bone development (especially the bones of the hands and elbows)  a larger than usual number of moles on the skin  edema or extra fluid in the hands and feet Physical Feautures

8   There is no specific cure for Turner Syndrome.  There are only treatments to better the condition -Growth hormone treatment ( improves growth, helps girls reach a normal height) -Estrogen Replacement ( helps girls develop physical changes of puberty) -In vitro fertilization ( helps some women with turner syndrome become pregnant) Medical Care

9  How do you identify Turner Syndrome? Females with Turner syndrome are usually diagnosed either at birth or around the time they might be expected to go through puberty. A karyotype test is used. The test counts the number of chromosomes and can identify any that are abnormally shaped or have missing pieces. Diagnosis

12   While Turner syndrome is genetic in that it involves the loss or abnormal expression of X-chromosome genes, it is not usually hereditary in the conventional sense.  one exception to this observation are families with a X-chromosome deletion which is stable enough to be passed down through the generations and which also allows fertility. Is it hereditary?

13   Turner syndrome affects all races, nationalities and regions of the world equally, and parents who have produced many unaffected children may still have a child with Turner syndrome. There are no known toxins or environmental hazards that increase the chances of Turner syndrome.  In other words, any female can get TS. Who can get TS?

14  What it looks like ?
