Especially in mosaic cases of Turner syndrome that contains Y-chromosome (e.g. [27], The syndrome is named after Henry Turner, an endocrinologist from Illinois, who described it in 1938. In the majority of Turner syndrome patients with hypertension, no specific cause is known. A test called a karyotype, also known as a chromosome analysis, analyzes the chromosomal composition of the individual. T Indeed, these same risk factors are found in more than 90% of patients with Turner syndrome who develop aortic dilatation. TS was first described in the United States in 1938 by Dr. Henry Turner. A girl with Turner syndrome is relatively small from infancy and usually falls below the 5th percentile for height on age- and sex-specific growth charts by 10 years of age. We hope this information is helpful. Conductive hearing losses are more commonly seen with children than adults and becomes more of a sensorineural pattern once in the adolescence age. Routine surveillance is highly recommended. Different karyotypes may have differing rates of cardiovascular malformations. The term monosomy is used to describe the absence of one member of a pair of chromosomes. The recurring AOM can also be a predisposition to cholesteatomas. Usually, fetuses with Turner syndrome can be identified by abnormal ultrasound findings (i.e., heart defect, kidney abnormality, cystic hygroma, ascites). This may also manifest itself as a difficulty with motor control or with mathematics. ... recurrent/severe otitis media. The fourth metacarpal bone (fourth toe and ring finger) may be unusually short, as may the fifth. The risk of developing type 2 diabetes can be substantially reduced by maintaining a healthy weight. The fetuses diagnosed through positive maternal serum screening are more often found to have a mosaic karyotype than those diagnosed based on ultrasonographic abnormalities, and Therefore, prophylactic antibiotics should be considered when procedures with a high risk of endocarditis are performed, such as dental cleaning.[27]. However, bicuspid valves are more likely to deteriorate and later fail. Growth hormone therapy. A coarctation of the aorta in a female is suggestive of Turner syndrome and suggests the need for further tests, such as a karyotype. Due to inadequate production of estrogen, many of those with Turner syndrome develop osteoporosis. [61] Turner syndrome accounts for about 10 percent of the total number of spontaneous abortions in the United States. [21] The variations found in the different studies are mainly attributable to variations in noninvasive methods used for screening and the types of lesions that they can characterize. This has been confirmed by a study that evaluated 40 patients with Turner syndrome. Meiotic errors that lead to the production of X with p arm deletions or abnormal Y chromosomes are also mostly found in the father.

Ullrich–Turner syndrome; Bonnevie–Ullrich–Turner syndrome; Girl with Turner syndrome before and after an operation for neck-webbing, Broad chest (shield chest) and widely spaced nipples, Rudimentary ovaries gonadal streak (underdeveloped gonadal structures that later become fibrotic), High waist-to-hip ratio (the hips are not much bigger than the waist), Nonverbal learning disability (problems with maths, social skills, and spatial relations). In general, Turner syndrome is considered to be a sporadic condition. [37], Women with Turner syndrome are almost universally infertile. Recurrent Otitis Media & Turner Syndrome Symptom Checker: Possible causes include Turner Syndrome. It is a chromosomal condition describing girls and women with common features, physical traits and medical conditions caused by the complete or partial absence of the second sex chromosome. Sometime the kidney may be malformed or be in the wrong position in the body. [55], Turner syndrome can be diagnosed postnatally at any age. 69.1% of cases had one anomaly present, and 30.9% had two or more anomalies. Nonetheless, the aortic root diameters found in Turner syndrome patients were still well within the limits. Cardiovascular abnormalities are common in women with Turner's syndrome (Lippe, 1991).

It is usually isolated, but it may be seen in combination with other anomalies, particularly coarctation of the aorta. ", "What are common treatments for Turner syndrome? 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. [1] Typically, they develop menstrual periods and breasts only with hormone treatment, and are unable to have children without reproductive technology. [4], Turner syndrome occurs in between one in 2,000[6] and one in 5,000 females at birth. Also, abnormalities in other mesenchymal tissues (bone matrix and lymphatic vessels) suggests a similar primary mesenchymal defect in patients with Turner syndrome. [7], Approximately 99 percent of fetuses with Turner syndrome spontaneously terminate during the first trimester. Some Turner syndrome patients may have a cell line containing Y chromosome material which is associated with an increased risk of gonadoblastoma. To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. However, its relative risk is 320 in comparison with the general population. Of the following common symptoms of Turner syndrome, an individual may have any combination of symptoms and is unlikely to have all symptoms. [31], Aortic dissection affects 1 to 2% of patients with Turner syndrome. Women with this condition tend to be shorter than average and are usually unable to conceive a child (infertile) because of an absence of ovarian function. [27] Usually it is hypothyroidism, specifically Hashimoto's thyroiditis. The most frequent karyotype is 45,X monosomy (40–50%), but others are also reported, and notably mosaic karyotypes (30–40%); X-chromosome structure abnormality, such as duplication (isochromosome Xp or Xq), deletion or X ring … Sometimes, fetuses with Turner syndrome are identified by abnormal ultrasound findings (i.e. For couples ascertained following recurrent miscarriage, the risk of chromosomally unbalanced pregnancies surviving to term… About 1 in every 2,500 newborn babies have Turner syndrome.1 Yet according to research, monosomy X is present in 1–2% of all conceptions, but about 99% of affected babies are miscarried or stillborn. [4] Human growth hormone injections during childhood may increase adult height. Turner syndrome is a lifelong diagnosis and requires consistent follow-up. I It is assumed that the likelihood of recurrence is similar to that in the general population (in other words, no increased risk for couples who have had a previous affected pregnancy). [45][46] About 75% of people with Turner syndrome have some hearing loss, with the most common presenting as a high frequency sensorineural hearing loss (HFSNHL) across all ages. Turner syndrome (TS) occurs in approximately one out of every 2,000- 4,000 female live births. The increased decline tends to occur in the higher frequency range, with a rate of around 0.8-2.2 dB a year. Many complications are associated with the disease, such as short stature, heart and kidney malformations, ovarian failure, increased risk for obesity, diabetes, and elevated blood pressure. However, it is also common for it to go undiagnosed for several years, often until the girl reaches the age of puberty and fails to develop typically (the changes associated with puberty do not occur). [5], Turner syndrome is not usually inherited; rather, it occurs during formation of the reproductive cells in a parent or in early cell division during development. These abnormalities can increase the risk … The abnormal cells may have only one X (monosomy) (45,X) or they may be affected by one of several types of partial monosomy like a deletion of the short p arm of one X chromosome (46,X,del(Xp)) or the presence of an isochromosome with two q arms (46,X,i(Xq))[51] Turner syndrome has distinct features due to the lack of pseudoautosomal regions, which are typically spared from X-inactivation. How can I find a genetics professional in my area? While some women with Turner syndrome have successfully become pregnant and carried their pregnancies to term, this is very rare and is generally limited to those women whose karyotypes are not 45,X. As more women with Turner syndrome complete pregnancy thanks to modern techniques to treat infertility, it has to be noted that pregnancy may be a risk of cardiovascular complications for the mother. Arterial hypertension is frequently seen. For example:[57], Turner syndrome occurs in between one in 2000[6] and one in 5000 females at birth. R Recurrence in subsequent pregnancies is rare, but has occurred. Two studies have suggested aortic dilatation in Turner syndrome, typically involving the root of the ascending aorta and occasionally extending through the aortic arch to the descending aorta, or at the site of previous coarctation of the aorta repair. This variety accounts for around 2–4% of all Turner syndrome cases. As the empirical observed risk is 1 in 8 one can estimate that only 1 in 4 (1/2 × 1/8) of such families will have an X linked disorder. The loss or alteration of the X chromosome occurs randomly. heart defect, kidney abnormality, cystic hygroma, ascites). It is also associated with an increased risk of bone fractures. [12] Diagnosis is based on physical signs and genetic testing. I underwent an IVF cycle and got pregnant but miscarried at 9 weeks. More than 50% of the cardiovascular malformations of individuals with Turner syndrome in one study were bicuspid aortic valves or coarctation of the aorta (usually preductal), alone or in combination.[23]. Get the latest research information from NIH: https://www.nih.gov/coronavirus (link is external). Rare exceptions may include the presence of a balanced translocation of the X chromosome in a parent, or where the mother has XO mosaicism restricted to her germ cells. - MedicineNet", "Long-term safety of recombinant human growth hormone in turner syndrome", "Growth hormone treatment of early growth failure in toddlers with Turner syndrome: a randomized, controlled, multicenter trial", "Studying early lethality of 45,XO (Turner's syndrome) embryos using human embryonic stem cells", "Care of girls and women with Turner syndrome: a guideline of the Turner Syndrome Study Group", Turner Syndrome at the National Institute of Child Health and Human Development, Endocrine and Metabolic Diseases Information Service, Acute myeloblastic leukemia with maturation, 46,XX testicular disorders of sex development, https://en.wikipedia.org/w/index.php?title=Turner_syndrome&oldid=991324263, Short description is different from Wikidata, Wikipedia articles needing clarification from April 2016, Wikipedia medicine articles ready to translate, Creative Commons Attribution-ShareAlike License. [5] Henry Turner first described the condition in 1938. In the remainder, it is usually associated with cardiovascular or kidney abnormalities, including coarctation of the aorta. The most commonly observed are congenital obstructive lesions of the left side of the heart, leading to reduced flow on this side of the heart. [4] Estrogen replacement therapy can promote development of the breasts and hips. The condition is thought to be a factor in roughly 10% of all first trimester miscarriages. Although the recurrence risk is not increased, genetic counseling is often recommended for families who have had a pregnancy or child with Turner syndrome.A test, called a karyotype or a chromosome analysis, analyzes the chromosomal composition of the individual. Withdrawal bleeding can be induced monthly, like menstruation, or less often, usually every three months, if the patient desires. Turner syndrome occurs in one out of every 2,500 to 3,000 live female births. Most of these significant conditions are treatable with surgery and medication. Chromosomal disorder in which a female is partly or completely missing an X chromosome, Pathogenesis of aortic dissection and rupture, "What are the symptoms of Turner syndrome? Turner syndrome may be diagnosed by amniocentesis during pregnancy. The prevalence of this abnormality also is low (around 2.9%) in Turner syndrome. Indeed, several studies had suggested an increased risk for aortic dissection in pregnancy. If detected, it can be easily treated with thyroid hormone supplements. Considering the increased risk of gonadal tumors in such patients, early investigation and individual management, including prophylactic gonadectomy, are recommended. Patients with Turner syndrome are at risk of congenital heart defects (e.g., coarctation of aorta, bicuspid aortic valve) and may have progressive aortic root dilatation or dissec- tion. This chromosome variation happens randomly when the baby is conceived in … [11] The chromosomal abnormality may be present in just some cells in which case it is known as TS with mosaicism. The association between a similar defect and aortic dilatation is well established in such conditions such as Marfan syndrome. So, the risk of aortic dissection in Turner syndrome appears to be a consequence of structural cardiovascular malformations and hemodynamic risk factors rather than a reflection of an inherent abnormality in connective tissue. Associated syndromes are found in 15% of cases. However, learning difficulties are common among women with Turner syndrome, particularly a specific difficulty in perceiving spatial relationships, such as nonverbal learning disorder. The following information may help to address your question: What is the recurrence risk for Turner syndrome? From table 1, the empirical recurrence risk for the parents is 1 in 7.5, in round figures 1 in 8. The natural history of aortic root dilatation is still unknown, but it is linked to aortic dissection and rupture, which has a high mortality rate. As with the other cardiovascular malformations, complications of aortic dilatation is commonly associated with 45,X karyotype.[27]. We are doing a second IVF cycle and are wondering if it is worth doing genetic testing before we transfer the next embryo. ... Risk factors. [15], Despite the excellent postnatal prognosis, 99% of Turner syndrome conceptions are thought to end in miscarriage or stillbirth,[16] and as many as 15% of all spontaneous abortions have the 45,X karyotype. An example is kidney abnormalities, which include recurrent urinary tract infections (UTI). CONCLUSION: (1) Abnormal karyotype is an important cause of congenital malformations; (2) The age pregnant women abnormal pregnancy history, IUGR and poly/oligohydramnios all may be the high risk factors of congenital malformations; (3) The recurrence rate of malformations rises after the first malformed newborn's birth. Rare exceptions may include the presence of a balanced translocation of the X chromosome in a parent, or where the mother has 45,X mosaicism restricted to her germ cells.[54]. heart defect, kidney abnormality, cystic hygroma, ascities). Normal skeletal development is inhibited due to a large variety of factors, mostly hormonal. Warm regards, [47][48][49] People with TS tend to have more of a progressive hearing loss with a higher decline rate than those in their corresponding age groups with hearing loss. The kidneys may be malformed or in the wrong position in the body. If the mother is a carrier, the risk for each son will be 1 in 2. However, as noted above, kidney problems may be associated with hypertension. [32] Turner syndrome does not typically cause intellectual disability or impair cognition. Since bicuspid valves are capable of regulating blood flow properly, this condition may go undetected without regular screening. [1] Most people with TS have normal intelligence, however many have troubles with spatial visualization that may be needed for mathematics. In rare cases, Turner syndrome may be caused by a missing piece (partial … Other congenital cardiovascular malformations, such as partial anomalous venous drainage and aortic valve stenosis or aortic regurgitation, are also more common in Turner syndrome than in the general population. Turner syndrome is a female-only genetic disorder that affects about 1 in every 2,000 baby girls. Get the latest public health information from CDC: https://www.coronavirus.gov (link is external) A single, horseshoe-shaped kidney on one side of the body. [40] Some women with Turner syndrome who are unable to conceive without medical intervention may be able to use IVF or other fertility treatments.[41]. Up to 15% of adults with Turner syndrome have bicuspid aortic valves, meaning only two, instead of three, parts to the valves in the main blood vessel leading from the heart are present. As this appears to be a random event, Turner syndrome is generally not inherited and risk of recurrence in subsequent pregnancies is minimal. Women with Turner syndrome are at a moderately increased risk of developing type 1 diabetes in childhood and a substantially increased risk of developing type 2 diabetes by adult years. Pregnancies among Turner's syndrome women are not without risk. This page was last edited on 29 November 2020, at 13:30. Estimates of the prevalence of this malformation in patients with Turner syndrome range from 6.9[24] to 12.5%. [29] However, no evidence suggests that patients with Turner syndrome have a significantly higher risk of aortic dilatation and dissection in absence of predisposing factors. Recurrent AOM predisposes to cholesteatoma. Bone mineral density can be measured at regular intervals using a dual-energy X-ray absorptiometry (DEXA) scan to assess any change with time. [27], Recurrent acute otitis media (AOM) and otitis media with effusion (OME) commonly occur in children with Turner syndrome during the preschool age, which can persist or develop later in childhood. [29], Whether aortic root diameters that are relatively large for body surface area but still well within normal limits imply a risk for progressive dilatation remains unproven. ", Eunice Kennedy Shriver National Institute of Child Health and Human Development, "How do health care providers diagnose Turner syndrome? [3], No cure for Turner syndrome is known. [36] Research shows a possible association between age at diagnosis and increased substance use and depressive symptoms. [53] Isochromosome X or ring chromosome X on the other hand are formed equally often by both parents. [1] Vision and hearing problems occur more often. To determine the prevalence and risk factors of ear disease in Turner syndrome (TS), propose an algorithm for future surveillance and recommend preventative strategies. Less common are pigmented moles, hearing loss, and a high-arch palate (narrow maxilla). [23], The prevalence of aortic root dilatation ranges from 8.8[29] to 42%[27] in patients with Turner syndrome. Turner syndrome may be diagnosed by amniocentesis or chorionic villus sampling during pregnancy. Estrogen therapy does not make a woman with nonfunctional ovaries fertile, but it plays an important role in assisted reproduction; the health of the uterus must be maintained with estrogen if an eligible woman with Turner Syndrome wishes to use IVF (using donated oocytes). Strangely, Turner syndrome seems to be associated with unusual forms of partial anomalous venous drainage. Turner syndrome is a chromosomal condition that alters development in females. CONCLUSION: The prevalence of gonadal tumor in patients with 45,X/46,XY mosaicism may vary according to the phenotype, and high in patients with female phenotype. Methods: We reviewed the records of 140 patients to evaluate the presence of familial TS occurrence. Usually, estrogen replacement therapy is used to spur the growth of secondary sexual characteristics at the time when puberty should onset. This includes bicuspid aortic valve and coarctation (narrowing) of the aorta. Besides fetal problems, pregnancy in TS girls is of high risk for the mothers as well. In most cases, Turner syndrome is a sporadic event, and for the parents of an individual with Turner syndrome the risk of recurrence is not increased for subsequent pregnancies. About one-third of all women with Turner syndrome have one of three kidney abnormalities: Some of these conditions can be corrected surgically. Recurrent idiopathic brachial neuritis attacks (ie, Parsonage-Turner syndrome) in contrast most commonly are seen in persons with a family history and a discoverable genetic cause by SEPT9 mutations, which tested negative in this patient. This abnormality is a relatively rare congenital heart disease in the general population. KEY POINTS: ACOG requires all women be offered prenatal screening (biochemical/ cfDNA ) or invasive diagnostic testing (amniocentesis/ CVS) conversely, those with mosaic karyotypes are less likely to have associated ultrasound abnormalities. Genetic, hormonal, and medical problems associated with TS are likely to affect psychosexual development of female adolescent patients, and thus influence their psychological functioning, behavior patterns, social interactions, and learning ability. [8] Generally people with TS have a shorter life expectancy, mostly due to heart problems and diabetes. Other features may include a small lower jaw (micrognathia), cubitus valgus,[14] soft upturned nails, palmar crease, and drooping eyelids. Two studies found a rate of cardiovascular malformations of 30%[24] and 38%[25] in a group of pure 45,X monosomy. A lot of these problems will require multiple specialists to be involved in care. Even with these abnormalities, the kidneys of most women with Turner syndrome function normally. contact us. [7] All regions of the world and cultures are affected about equally. This is t… 1/2,500 - 1/5,000 liveborn females based on screening newborn pop. Turner syndrome is caused by the absence of one complete or partial copy of the X chromosome in some or all the cells. In childhood, a short stature can be indicative of Turner syndrome.[56]. [33] While it is not correctable, in most cases it does not cause difficulty in daily living. This is the test of choice to diagnose Turner syndrome. The total recurrence rate was 30%. It seems that the high risk of aortic dissection during pregnancy in women with Turner syndrome may be due to the increased hemodynamic load rather than the high estrogen level. Also, a rare variety of Turner syndrome, known as "Ring-X Turner syndrome", has about a 60% association with intellectual disability[clarification needed]. Methods Review of TS patients seen in the West of Scotland between 1989 and 2015, with questionnaire follow‐up in 2015. Sometimes, fetuses with Turner syndrome are identified by abnormal ultrasound findings (i.e. [8][10] Turner syndrome is due to a chromosomal abnormality in which all or part of one of the X chromosomes is missing or altered. With a rate from 12.5%[24] to 17.5% (Dawson-Falk et al., 1992), bicuspid aortic valve is the most common congenital malformation affecting the heart in this syndrome. [43][44] People with the monosomy 45, X karyotype have an increased rate of hearing loss over other TS karyotype variants. Chromosomal abnormalities: horseshoe kidney is found in 30% of cases of Turner syndrome and in 20% of trisomy 18. Failure to develop secondary sex characteristics (sexual infantilism) is typical. Spontaneous pregnancy occurs in 2%–7% of TS girls and is associated with a high rate of miscarriages, stillbirths, malformations, and chromosomal aberrations. Approximately one-third of all women with Turner syndrome have a thyroid disorder. [5] In mosaic individuals, cells with X monosomy (45,X) may occur along with cells that are normal (46,XX), cells that have partial monosomies, or cells that have a Y chromosome (46,XY). [27], Cardiovascular malformations (typically bicuspid aortic valve, coarctation of the aorta, and some other left-sided cardiac malformations) and hypertension predispose to aortic dilatation and dissection in the general population. , Social difficulties appear to be an apparent linear relation between hearing loss, and a high-arch palate narrow!
