im doing this for a research and i need references from anyone that answers this question please. Of the following common symptoms of Turner syndrome, an individual may have any combination of symptoms and is unlikely to have all symptoms. 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. While very few women with Turner syndrome menstruate spontaneously, estrogen therapy requires a regular shedding of the uterine lining ("withdrawal bleeding") to prevent its overgrowth. Usually, a woman has two X chromosomes. - 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. [53] Overall, the functional X chromosome usually comes from the mother. One in … The risk of developing type 2 diabetes can be substantially reduced by maintaining a healthy weight. ", "Optimising management in Turner syndrome: from infancy to adult transfer", "How many people are affected or at risk? [1] Often, a short and webbed neck, low-set ears, low hairline at the back of the neck, short stature, and swollen hands and feet are seen at birth. The chromosome analysis determines whether or not there is a missing X chromosome or abnormality of one of the X chromosomes. Turner syndrome occurs in about 1 in 2,500 newborn girls worldwide, but it is much more common among pregnancies that do … Usually, fetuses with Turner syndrome can be identified by abnormal ultrasound findings (i.e., heart defect, kidney abnormality, cystic hygroma, ascites). 45,X/46,XY) due to the risk of development of ovarian malignancy (most common is gonadoblastoma) gonadectomy is recommended. [12] Diagnosis is based on physical signs and genetic testing. Girls with Turner syndrome are usually shorter than their peers. [27][42] Turner syndrome is characterized by primary amenorrhoea, premature ovarian failure (hypergonadotropic hypogonadism), streak gonads and infertility (however, technology (especially oocyte donation) provides the opportunity of pregnancy in these patients). Turner’s syndrome is a random genetic disorder that affects women. There are quite a few cases in which the chromosome can be missing from certain cells but not from others, which is officially diagnosed as “Turner Mosaicism.”. thanks a lot ... 1 decade ago. [62] In Europe, it is often called Ullrich–Turner syndrome or even Bonnevie–Ullrich–Turner syndrome to acknowledge that earlier cases had also been described by European doctors. Usually, a person has 46 chromosomes in each cell, divided into 23 pairs, which includes two sex chromosomes. [43][44] People with the monosomy 45, X karyotype have an increased rate of hearing loss over other TS karyotype variants. Following the guidance and expert recommendations of your doctor and licensed specialists will allow you to have a much better chance of living a long and happy life while keeping this condition well-managed. This is solely because of the fact that studies have proven that they are the most common reasons why people that have Turner Syndrome die. Young girls that have are diagnosed with this particular abnormality actually experience a considerable level of gonadal dysfunction as well. During her stay on the ward, in the light of the distinctive facial features, mental retardation, and social behaviour patterns, the possibility of Williams syndrome emerged. In Russian and USSR literature it is called Shereshevsky–Turner syndrome to acknowledge that the condition was first described as hereditary in 1925 by the Soviet endocrinologist Nikolai Shereshevsky [ru], who believed that it was due to the underdevelopment of the gonads and the anterior pituitary gland and was combined with congenital malformations of internal development.[63]. TS occurs in approximately 1 in 2,500 female births, however, it is much more common among pregnancies that do not survive to term.

It is important to note that affected individuals may not have all of the symptoms discussed below. Only a small number of patients (around 10%) have no apparent predisposing risk factors. On September 10, Donnie Heaton will celebrate his 21rst birthday. The first case of Turner’s syndrome was a 45X karyotype in a 14 year old girl from London. Donnie is one of the oldest with the disorder, and his mother was 42 when she had him. [3], No cure for Turner syndrome is known. In the majority of cases where monosomy occurs, the X chromosome comes from the mother. 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? It is named after an endocrinologist who first described it, Henry H. Turner. For girls and women who are treated promptly and follow their treatment plans, they can have a normal or near-normal life expectancy. [52] This may be due to a nondisjunction in the father. 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. Also, abnormalities in other mesenchymal tissues (bone matrix and lymphatic vessels) suggests a similar primary mesenchymal defect in patients with Turner syndrome. [64] It was found in a 14-year-old girl with signs of Turner syndrome. [38][39] Even when such pregnancies do occur, there is a higher than average risk of miscarriage or birth defects, including Turner syndrome or Down syndrome. [13] In 1964, it was determined to be due to a chromosomal abnormality.[13]. One of the most common chromosomal abnormalities that seems to be spreading progressively over time and becoming more and more prevalent is Turner Syndrome.
