Why is Turner syndrome important?
The missing or changed X chromosome of Turner syndrome causes problems during fetal development and other developmental problems after birth — for example, short stature, ovarian insufficiency and heart defects. Physical characteristics and health complications that arise from these chromosomal issues vary greatly.
Is Turner’s syndrome life threatening?
The heart defects associated with some cases of Turner syndrome can increase the risk of severe, life-threatening complications including high blood pressure of the arteries of the lungs (pulmonary hypertension) or aortic dissection, a condition in which there is a tear in the inner wall of the aorta.
Who is most affected by Turner syndrome?
Turner syndrome is a chromosomal condition that affects development in females. The most common feature of Turner syndrome is short stature, which becomes evident by about age 5. An early loss of ovarian function (ovarian hypofunction or premature ovarian failure) is also very common.
How long do people live with Turner’s syndrome?
The prognosis, or outlook, for women with Turner syndrome (TS) is usually good. Life expectancy for Turner syndrome might be slightly shorter, but by testing for and treating the conditions that come with TS, women with TS can expect to live essentially normal lives.
Why is it called Turner syndrome?
Turner syndrome results from missing all or part of one of the X chromosomes. Turner syndrome occurs in 1 in 2,000 to 2,500 females. The name “Turner syndrome” comes from Dr. Henry Turner, the physician who first described the collection of findings in 1938.
How many people are diagnosed with Turner syndrome each year?
Turner is the second most common genetic disorder. It is estimated that the disorder affects 1 in 2,000 females; 1,000 new baby girls are born with the Syndrome annually (one every eight hours).
Can Turner syndrome get pregnant?
Most women with Turner syndrome cannot get pregnant naturally. Those who can are at risk for blood pressure-related complications, which can lead to premature birth or fetal growth restriction. Pregnancy also is associated with increased risk for maternal complications, including aortic dissection and rupture.
Who discovered Turner syndrome?
How many people in the world have Turner’s syndrome?
Thus, TS is responsible for 7–10% of all spontaneous abortions. TS affects approximately 1 in 2,500 live female births (5, 6), corresponding to approximately 1.5 million women worldwide.
Who invented Turner syndrome?
Turner syndrome occurs in 1 in 2,000 to 2,500 females. The name “Turner syndrome” comes from Dr. Henry Turner, the physician who first described the collection of findings in 1938. It was not until 1959 that the cause of Turner syndrome was identified.
How was Turner syndrome discovered?
Turner syndrome was first discovered in 1938 by Dr. Henry Turner while studying a group of 7 girls who all had the same unusual developmental and physical features. Though most people today refer to the condition as Turner syndrome or TS, your doctor may call it gonadal dysgenesis.
How was Turner syndrome named?
Can Turner syndrome have babies?
Is Turner syndrome only in females?
Turner syndrome is a female-only genetic disorder that affects about 1 in every 2,000 baby girls. A girl with Turner syndrome only has 1 normal X sex chromosome, rather than the usual 2.
How is Turner syndrome formed?
Turner syndrome occurs when part or all of an X chromosome is missing from most or all of the cells in a girl’s body. A girl normally receives one X chromosome from each parent. The error that leads to the missing chromosome appears to happen during the formation of the egg or sperm.
How many people have Turner’s syndrome in the world?
How many types of Turner syndrome are there?
There are 2 types of Turner syndrome: monosomy X TS and mosaic TS. About half of all girls with Turner syndrome have a monosomy disorder. Monosomy means that a person is missing one chromosome in the pair. Instead of 46 chromosomes, the person has only 45 chromosomes.
