What is Turner syndrome? Turner syndrome (45,X) is a genetic disorder that occurs only in females and arises from partial or complete absence of the X chromosome. H.H.Turner first described Turner syndrome in 1938 and the chromosomal basis of this syndrome was established in 1959 by Ford. Turner syndrome occurs in 1 in 2500 female births. The physical phenotype of this syndrome includes: gonadal dysgenesis lack of pubertal maturation infertility short stature shield chest webbing of the neck coarctation of the aorta horseshoe kidney The neurocognitive profile of females with Turner syndrome includes: Preserved verbal skills Specific deficits in visuo-spatial tasks, visual memory, and arithmetic Verbal IQ is greater than Performance IQ T he psychosocial profile of females with Turner syndrome includes: Difficulty with school adjustment and facial affect recognition Social hypersensitivity Poor peer relations What causes Turner Syndrome? Turner syndrome is the only sex chromosome disorder in which complete absence of an X chromosome is compatible with life. The loss of one of the sex chromosomes in Turner syndrome probably occurs after the zygote has formed or just after the fusion of the gametes. It has been determined that approximately 50% of cases have a 45,X karyotype with the remainder having mosaic karyotypes. In addition, it has been found that in 70 to 80 % of the cases, the retained X is maternal in origin. Researchers have begun to speculate as to the possibility that genes are present on the X chromosome which are expressed differently depending on the parental origin of the X chromosome. The effects of genomic imprinting can be analyzed from the standpoint of physical and physiologic parameters in females with Turner syndrome.

Natascha was born at the last day of November 1996, already at birth we could see that something was wrong, but no one told us anything, until the third day, a doctor told us that she might have Turner Syndrome, but they had to do some test, Bloodtest to look after chromosones abnormalties, X-ray her kidneys, and there was this dissonace at her heart, so they had to scan her. all these examinations were done by the next couple of days, and the results from the bloodtest came at last, and they said " She is a Turner girl " our whole world fell apart that day, because we also knew that she had to go through an heart operation, in a age of 3 months, so we have to go and worry about this operation for 3 months, and the doctors told us a lot about turner Syndrome, and we got really scared because all that that could happen to our little babygirl. But now 10 months later, we can look happily back, because the heartoperation, was an succes, she is growing like any other girl, she is like any other girl, exept two things 1. she has a big scar on her chest.

MAIN SEARCH INDEX Turner syndrome Definition Description Causes and symptoms Diagnosis ... Resources Definition Turner syndrome is a chromosomal disorder affecting females wherein one of the two X-chromosomes is defective or completely absent. Description Chromosomes are structures in the nucleus of every cell in the human body. Chromosomes contain the genetic information necessary to direct the growth and normal functioning of all cells and systems of the body. A normal individual has a total of 46 chromosomes in each cell, two of which are responsible for determining gender. Normally, females have two X-chromosomes and males have one X and one Y-chromosome. In Turner syndrome, an error occurring very early in development results in an abnormal number and arrangement of chromosomes. Most commonly, an individual with Turner syndrome will be born with 45 chromosomes in each cell rather than 46. The missing chromosome is an X-chromosome. The affected person is always female. The prevalence of Turner syndrome is widely reported as being approximately one per 2,000 live female births, although researchers have reported prevalence rates that range from one in 3,125 to one in 5,000 live female births. About 1% to 2% of all female conceptions have a missing X-chromosome. Of these, the majority (99%) spontaneously abort, usually during the first trimester of

Turner syndrome was initially described by Dr. Henry Turner in 1938. Turner syndrome occurs in approximately 1 of 2,500 females. About 95 percent of fetuses are spontaneously miscarried during pregnancy and thus only 5 percent survive to term. Most cases of Turner syndrome occur randomly and thus do not carry a recurrence risk. Prenatal diagnosis is available through amniocentesis (sampling of the fluid which surrounds the baby before birth) to look for the abnormality of the X chromosome. Since patients with Turner syndrome are unable to have children, there is no risk of mother-daughter transmission. Return to Top Genetic abnormality of Turner syndrome Turner syndrome is characterized by an abnormality in the X chromosome. Normally females have two X chromosomes (and males have one X and one Y). In Turner syndrome, females often have only a single X chromosome. (This occurs in 60 percent of patients with Turner syndrome.)

Children with Turner syndrome only have one functioning X chromosome (unlike normal females who have two functioning X chromosomes [46, X, X]), and the other one may be absent [45, X] in all cells, or just some cells which is called a mosaic [45, X/46, X, X], or there may be a fragment of the second X chromosome present in some cells. It is not known what causes Turner syndrome and it is not associated with advanced maternal age. Turner syndrome is found in about 1 out of every 2000-3000 live born females.

Turner syndrome is a genetic condition that occurs in females who have only one X chromosome, instead of the usual two. Typical features include short stature (height); webbed neck; underdeveloped breasts; abnormalities of the eyes and bones; and not getting your period (no menstruation). To learn more about genetics and to better understand how genes cause syndromes, see Your Child: Genetic Syndromes If your daughter has the physical features of Turner syndrome, then she should be tested to find out for sure whether she has it. A blood test can be done to check for the absence of an X chromosome.

About 1 in every 8,000 babies born has Turner syndrome. No cause has been identified for Turner syndrome. At birth, female babies with Turner syndrome are below average in weight and length. They have slightly swollen hands and feet, and sometimes have swelling at the nape of the neck. Girls with Turner syndrome are shorter than normal, and have short, webbed necks with extra, loose skin. The jaw is usually small and the ears are large. An extra fold of skin is often seen on either side of the nose, close to the eye (called an epicanthic fold). The chest is usually quite broad, with increased distance between the nipples.

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 Xs 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 2,500 females born. 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 (having only a single X chromosome) was identified.

Usually, men have an X and a Y, while women have two X's. In Turner syndrome, a baby girl develops with only one X chromosome. The incidence is 1 out of 3,000 live births. Turner syndrome usually occurs sporadically, which means that the mutation occurs in fetal development and is not inherited from either parent. In rare cases, a parent silently carries rearranged chromosomes that can result in Turner syndrome in a daughter; this is the only situation in which Turner syndrome is inherited.

Turner Syndrome Turner syndrome is a chromosomal condition that occurs when one of the two X chromosomes found in females is missing or incomplete. It is a chromosomal condition that only affects females. It is one of the most common chromosomal conditions occurring in about 1 out of every 2,500 live female births. What causes Turner syndrome? Turner syndrome is caused by the complete or partial absence of one of the two X chromosomes normally found in a woman. There are no know reasons for the complete or partial absence of one of the X chromosomes and the condition appears to occur randomly. How is Turner syndrome diagnosed? Turner syndrome is diagnosed using a blood test known as a karyotype. The karyotype blood test analyzes the chromosomal composition of the individual and determines whether the X chromosome is absent. What are the characteristics of someone with Turner syndrome? A shorter stature and lack of ovarian development are the most common characteristics. A woman with Turner syndrome may exhibit any of the following physical characteristics: Arms that are slightly turned out at the elbow A low hairline in the rear of the head Are there any health concerns for someone with Turner Syndrome?

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.
