Genetic Science Learning Center at the Eccles Institute of Human Genetics University of Utah Home ... What Can Our Chromosomes Tell Us? Turner Syndrome Turner Syndrome Turner Syndrome affects 60,000 girls and women in the United States. This disorder occurs in 1 in 2000 to 1 in 2500 live births, with about 800 new cases diagnosed each year. Girls with Turner Syndrome do not develop secondary sex characteristics such as breast tissue and underarm or pubic hair. Women and girls with Turner Syndrome have only one X chromosome . This is an example of monosomy See the box below to learn more about how the gender of an individual is determined. Where does the single X chromosome come from? In 75 to 80 percent of cases, the single X chromosome comes from the mother's egg because the father's sperm that fertilizes the egg is missing a sex chromosome. How do chromosomes determine the gender of an individual? It took scientists a long time to work out the puzzle of how sex chromosomes determine an individual's gender. Here's the evidence: X + X = FEMALE Y + X = MALE X + = FEMALE (Turner Syndrome) Y + X + X = MALE (Klinefelter Syndrome) What's the key feature? What chromosomes do the males have that the females don't have?

Turner syndrome From Wikipedia, the free encyclopedia. Turner syndrome is a human genetic abnormality , caused by a nondisjunction in the sex chromosomes that occur to females (1 out of every 2,500 births). Instead of the normal XX or XY sex chromosomes, only a single X chromosome is present. In Turner syndrome, female sexual characteristics are present but underdeveloped. People with Turner syndrome often have a short stature, webbed neck , low hairline, abnormal eye features and bone development and a "caved-in" appearance to the chest. Turner syndrome is a disorder caused by the loss of genetic material from one of the sex chromosomes. Humans normally have a total of 46 chromosomes (which are tiny, DNA -containing elements) that are present in every cell of the body. DNA encodes genes , which specify all the proteins that make up the body and control its functions. In humans, there are 23 matched pairs of chromosomes in every cell. Each cell contains 22 pairs of chromosomes called autosomes that are the same in males and females. The remaining pair of chromosomes, the X- and Y-chromosomes, are not shaped similarly, and thus are not matched in the same way as the autosomes. The X- and Y-chromosomes are called sex chromosomes. They are responsible for the difference in development between males and females. A Y-chromosome contains genes responsible for

Other physical features may include a webbed neck, heart defects, kidney abnormalities, and/or various other malformations. Normally, females have two X chromosomes. In some cases of Turner Syndrome, however, one X chromosome is missing from the cells (45,X); research studies suggest that approximately 40 percent of these individuals may have some Y chromosomal material in addition to the one X chromosome. In other affected females, both X chromosomes may be present, but one may have genetic defects. In still other cases, some cells may have the normal pair of X chromosomes while other cells do not (45,X/46,XX mosaicism). Although the exact cause of Turner Syndrome is not known, it is believed that the disorder may result from an error during the division (meiosis) of a parent's sex cells.

Longui E-mail: fisiolab@santacasasp.org.br Genet. Mol. Res. 1 (3): 266-270 (2002) Received April 4, 2002 Published September 23, 2002 ABSTRACT. Turner syndrome is caused by haploinsufficiency of the short arm of X-chromosome, and is usually diagnosed by karyotyping. This procedure is time-consuming, expensive and unfeasible for population screening. We propose molecular detection of 45XO Turner patients based on the ability of Hpa II, a methylation sensitive endonuclease, to induce the cleavage of non-methylated DNA in the active X-allele. Genomic DNA was obtained from 22 patients with Turner syndrome confirmed by karyotype (45XO, N = 18; 45XO/46XX, N = 4). After digestion, DNA was amplified with primers directed to exon 1 of the androgen receptor (AR) gene and to the GAPDH control gene. Normal control females or mosaic patients, with a second methylated X-chromosome, escaped from Hpa II digestion and produced a band corresponding to AR gene amplification. 45XO patients have just one active non-methylated X-chromosome, completely digested by

Therefore, there is a total of 45 chromosomes in each cell of the body, rather than 46. For example, if a baby is born with only one X sex chromosome, rather than the usual pair (either two X’s or one X and one Y sex chromosome), the baby would be said to have “monosomy X”.

Find a Doctor About Us Employment Alfred I. duPont Hospital ... Contact Us Frequently Asked Questions Turner Syndrome What is Turner syndrome? Turner syndrome is a chromosomal condition causing short stature and infertility in women and girls. What causes Turner syndrome? Turner syndrome is caused by the complete or partial absence of one of the two X chromosomes normally found in females. Is there a genetic or environmental factor associated with Turner syndrome? No. Turner syndrome is not associated with any environmental or any other factors generally associated with genetic problems. Despite many efforts, no real causes have been found for this condition. It appears to be a random event that can happen to anyone. What can be done for a patient with Turner syndrome? As a chromosomal condition, there is no cure for Turner syndrome the way that antibiotics can cure strep throat. However much can be done to manage the problem. Growth hormone, either alone or with a weak androgen, will improve speed of growth and probably increase final adult height. Growth hormone is approved by the Food and Drug Administration for treatment of Turner syndrome and is covered by many insurance plans. Estrogen replacement therapy has also been used to promote development of secondary sexual characteristics since the condition was described in 1938. This treatment is also important for maintaining good tissue and bone integrity.

The term "monosomy" is used to describe the absence of one member of a pair of chromosomes. Therefore, there is a total of 45 chromosomes in each cell of the body, rather than 46. For example, if a baby is born with only one X sex chromosome, rather than the usual pair (either two X's or one X and one Y sex chromosome), the baby would be said to have "monosomy X". Monosomy X is also known as Turner syndrome. What is Turner syndrome? Turner syndrome is a genetic disorder seen in girls that causes them to be shorter than others and to not mature sexually as they grow into adulthood. The severity of these problems varies among affected individuals. Other health problems may also be present involving the heart or renal system (i.e., kidneys). Many problems affecting girls with Turner syndrome can be managed or corrected with appropriate medical treatment. Turner syndrome occurs in one in 2500 females born. The name "Turner syndrome" comes from the physician, Dr. Henry Turner, who first described the collection of findings in 1938. It was not until 1959 that the cause of Turner syndrome (having only a single X chromosome) was identified.
