Zooming in
What is Turner Syndrome?
- Also known as Gonadal Dysgenesis, Turner Syndrome is the result of a chromosomal disorder in which a female is born with a missing "X" chromosome.
General Information
- Age: TS is an at-birth defect. The genetic makeup of the offspring is what causes the disease.
- Requires medical diagnosis
- Rare: fewer than 200,000 cases in the US per year
- Chronic impacts: Can last for a long time or the individual's lifetime
- Prognosis: No cure but hormone therapy is available and very helpful

There is no definite evolutionary factor of this disease. the deletion/missing of the last x chromosome is by chance.
Heart: congenital heart defect
Genome of Turner Syndrome
Klinefelder: A genetic condition in which a male is born with an extra copy of the X chromosome (results in INFERTILITY)
Triple X: An abnormality resulting in an extra X chromosome in some females (results in learning disabilites)
Whole body: high blood pressure, osteoporosis
Common: absence of menstruation, infertility, ear infections, widely spaced nipples, elbow deformity, hearing loss, kidney malformation, obesity, puffy hands & feet at birth, scoliosis, vision disorder, webbed neck
TS is X-Linked recessive
No defective genes
It is caused by abnormal or missing X chromosome on #23
