Here, we report a fetus with a mosaic karyotype: mos 45,X/46,X,del(Y)(q11.21). A case is reported of dysgenetic male pseudohermaphroditism (DMPH) having Turner stigmata and 45,X/46,X+mar karyotype. We aimed to investigate change over time in incidence, prevalence and age at diagnosis among Turner syndrome (TS), Klinefelter syndrome (KS), Triple X syndrome (Triple X) and Double Y syndrome (Double Y). Chronic myelogenous leukemia, a classic 9;22 translocation that is diagnostic of the disease. NOTE: Males may sometimes have the 45,X/46,XY mosaic karyotype, but this is not Turner syndrome. Girls and women with Turner syndrome need ongoing medical care from a variety of specialists. Parsonage Turner syndrome is usually characterized by the sudden onset of severe pain in the shoulder and upper arm, which is often described as sharp, aching, burning, stabbing, or throbbing. features of Turner syndrome. Here, we report a fetus with a mosaic karyotype: mos 45,X/46,X,del(Y)(q11.21). Share to Twitter Share to Facebook Share to Pinterest. We describe a case of Turner syndrome with a 46,XY genotype by conventional 5-cell karyotype who was subsequently found to have a mosaic genotype of 18% 45,X and 82% 46,XY by 50-cell FISH analysis. Administration of appropriate hormonal therapy may induce the installation of menstruation. Patau syndrome (Trisomy 13), caused by an extra chromosome 13. Turner syndrome (TS) is a rare genetic condition in which a girl or woman doesn’t have the usual pair of 2 X chromosomes. Turner's Syndrome. Turner Syndrome Causes, Symptoms And Karyotypes, Klinefelter Syndrome Causes, Symptoms And Karyotype, Escherichia Coli (E. Coli) Infection - Treatment And Prevention. Patients with Turner syndrome, often develop ear infections that can lead to deafness, also develop hypothyroidism or hyperthyroidism. Turner syndrome is defined by the presence of a single X chromosome (sex chromosome disease, and not an autosomal disease like Down syndrome), complete or partial monosomy which is present in all cells or only in a certain proportion and associates phenotypic aspects such as nanism, defects in development of ovaries and various visceral malformations. Klinefelter syndrome, the most common sex chromosome abnormality in males; caused by an extra X chromosome. Mosaicism 45x / 46XX in 15% of cases of Turner syndrome; X isochromosome,  46X,i(Xq) in 10% of cases of Turner syndrome; Mozacism 46X,i (Xq) / 46XX in 8% of cases of Turner syndrome; Deletions 46XXp- or 46XXq- in 6% of cases of Turner syndrome; Other mosaicism in 8% of cases of Turner syndrome. Since puberty, patients with Turner syndrome have short stature (150 cm in 90% of cases), which also stands in childhood (short stature after age 2-5 years), gonadal dysgenesis (fibrosis of gonads with follicles degenerate ) and absence of the installation of  secondary female sexual characteristics: primary amenorrhea, mammary glands are not developt, axillary and pubic hair growth are underrepresented and infertility. Noonan syndrome is a distinct disorder that can affect both males and females. Turner syndrome is caused by partial or complete loss (monosomy) of the second sex chromosome. Klinefelter syndrome, the most common sex chromosome abnormality in males; caused by an extra X chromosome (XXY). What is Turner syndrome? In males, this is simply referred to as 45,X/46,XY,male. Chromosomes are found in the nucleus of all body cells. The male patient exhibited short stature, hypospadias and bilateral cryptorchidism. Conclusion Patients with Turner syndrome are usually phenotypically female, and male cases are rarely reported. In males, they can range from a seemingly normal male to the presence of a variety of features which can include dysmorphic (abnormally formed) features, mild intellectual disabilities, infertility, Ulrich-Turner stigmata (drooping of upper eyelid, extra “webbing” on the neck), gonadal dysgenesis, infertility, low testosterone levels, and azoospermia (having no sperm). Moreover, 50% of patients with Turner syndrome, present a mosaic karyotype or structural aberrations of the second X chromosome. Hence, this is another … 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. Turner syndrome affects only females, resulting from a missing sex (X) chromosome. The marker chromosome of this patient consisted of most if not all of the short arm, including the sex determining region of the Y chromosome. The male sex has one X … Turner syndrome is distinguished from other sex chromosome abnormalities, in particular from Klinefelter syndrome, by a variety of karyotype. A skin sample from a 17-year-old female was received for routine karyotyping with a set of clinical features including clonic seizures, cardiomyopathy, hepatic adenomas, and skeletal dysplasia. In males, this is simply referred to as 45,X/46,XY,male. Thus, females with a normal chromosome make-up (karyotype) have 46 chr… It was found that 70% of cases with Turner syndrome appear as a non-mitotic disjunction with a preferential loss of the paternal X chromosome. Klinefelter's Syndrome Karyotype. Turner Syndrome is characterized cytogenetically by X chromosome monosomy, the presence of an abnormal X chromosome, or mosaicism of a 45,X cell line with another cell line, which might be 46,XX, 46,XY or have an abnormal sex chromosome rearrangement.2 The incidence of Turner syndrome is approximately 1 in 5000 newborn girls;2 97% of the TS conceptions are spontaneously aborted.2 On chromosomal analysis, the percentage occurrences of the various karyotypes observed in TS are 45,X (… Phenotype becomes evident with puberty, when appear gonadal dysgenesis which amplify the clinical dysfunction.

The human body has 46 (or 23 paired) chromosomes that store genetic material. The missing gene prevents the body from growing and developing normally. Typically, these men have dysmorphic features such as webbed neck, short stature, low-set ears and wide-set eyes. Turner syndrome (TS), also known 45,X, or 45,X0, is a genetic condition in which a female is partly or completely missing an X chromosome. Turner's syndrome, a form of gonadal dysgenesis resulting from a 45,X karyotype (X‐chromosomal monosomy), is characterized by female phenotype, short stature, a shieldlike chest, a short and sometimes webbed neck, low‐set ears, high‐arched palate, small mandible, and sexual infantilism. The aim of this study was to determine the association between karyotype and prevalence of BAV. The phenotype bears similarities to that of TURNER SYNDROME that occurs only in females and has its basis in a 45, X karyotype abnormality. It is estimated that the incidence of Turner syndrome, reported to all products of conception is 1% – 1.5%, Turner syndrome is one of the most common chromosomal abnormalities. Turner syndrome, characterized by the presence of a monosomy X cell line, is a common chromosomal disorder. They carry the genetic characteristics of each individual and they come in pairs. Recent work demonstrates that men with Klinefelter's syndrome (47,XXY men) have a similar risk of developing SLE as do women. For male‐predominant autoimmune diseases, women with X monosomy were at approximately doubled risk (SIR 2.3 [95% CI 0.9–4.7]), while among women with the isochromosome Xq karyotype, the SIR was 5.3 (95% CI 1.3–13.6), and among women with all other Turner's syndrome karyotypes, the SIR was 5.2 (95% CI 2.9–8.5). It was noted that 15 of 1000 fetuses from recognized pregnancies are with Turner syndrome, but 99% of them are ending in miscarriage in the first trimester of pregnancy.

Turner syndrome is related to the X chromosome, which is one of the two sex chromosomes. Turner syndrome, caused by missing one X chromosome in females. Karyotype of this syndrome is 45x. Noonan syndrome presents phenotypically as a male Turner syndrome (45,X). Turner's Syndrome Karyotype. A "normal" human being has 23 pairs of chromosomes, for a total of 46. The male karyotype is the chromosomal picture of a male characterized by the 23 rd chromosome pair. It concludes that monosomy X, would be lethal and that for survival would be required some degree of mosaicism. The presence of Turner stigmata in DMPH has not previously been demonstrated and the typical karyotype for DMPH is 46,XY, so we consider that the Turner stigmata seen in our patient may have resulted from his 45,X/46,X+mar karyotype, which is normally seen in Turner’s syndrome. It was noted that 15 of 1000 … - Costello Syndrome X and Y chromosomes determine your sex. The human body has 46 (or 23 paired) chromosomes that store genetic material. We receive one copy from each parent. However, Noonan syndrome occurs in both males and females with a normal sex chromosome constitution (46,XX and 46,XY). However, Noonan syndrome occurs in both males and females with a normal sex chromosome constitution (46,XX and 46,XY). Noonan syndrome is an autosomal dominantdisorder that is multi-systemic and occurs and affects approximately 1 in 1,000 to 2,500 people. - Neurofibromatosis 1 Sexual chromatin and chromosome analysis indicate that about 1 in 2500-3000 female newborns have a 45x karyotype, so they are diagnosed with Turner syndrome. Bruce O. Berg, in Textbook of Clinical Neurology (Third Edition), 2007. The incidence of Klinefelter syndrome is 1 to 500 in male newborns for 47XXY and 1 to 300 in spontaneous abortions, 1 to 50.000 for karyotype 48XXXY and 1 to 85.000 for karyotype 49XXXXY. An exact relation between the occurrence of BAV and a particular karyotype has not been established yet. Conventional karyotyping revealed a mosaic Turner syndrome karyotype with a cell line containing a small marker of X chromosome origin. The missing gene prevents the body from growing and developing normally. Gonadal dysgenesis is seen in the vast majority of cases, and almost all affected individuals are infertile (Sybert and McCauley 2004). Although this karyotype is relatively common in Turner’s syndrome and occasionally observed in mixed gonadal dysgenesis, … And TS isn't "on" any chromosome. Karyotype of this syndrome is 45x. Intelligence is usually average or below average (IQ = 70-120). Individuals with a mosaic 45,X/46,XY genotype have a variety of phenotypic presentations ranging from male to female which are not correlated with the perce… Background: Bicuspid aortic valve (BAV) represents one of the strongest risk factors for aortic dissection in Turner syndrome (TS). Followers. Turner syndrome cytogenetic variants and their frequency is the following:: The medical management of Turner syndrome: Biosynthesised growth hormone is administered at early ages to improve the stature with 10 cm. The 23 rd pair which is the sex chromosome pair has a long X chromosome and a shorter Y chromosome. The phenotype bears similarities to that of TURNER SYNDROME that occurs only in females and has its basis in a 45, X karyotype abnormality. However, the karyotype in these men is normal 46,XY and the chromosomal abnormality has not yet been identified. Is practice amniocentesis for fetal karyotype analysis. 45, X. Unaffected Male (pedigree symbol) An unshaded square on a pedigree represents _____. Noonan syndrome occurs in both males and females with a normal karyotype (46,XX and 46,XY). However, the karyotype in these men is normal 46,XY and the chromosomal abnormality has not yet been identified. Turner syndrome, characterized by the presence of a monosomy X cell line, is a common chromosomal disorder. NOTE: Males may sometimes have the 45,X/46,XY mosaic karyotype, but this is not Turner syndrome. Chronic myelogenous leukemia, a classic 9;22 translocation that is diagnostic of the disease. At birth, some signs may be considered pathognomonic for Turner syndrome: lymphedema of the dorasl part of the hands and feet, short neck, dysplastic and low implanted ears, light ptosis, hypoplastic mandible, dystrophic nails and pterigium coli (webbed neck). Rarely, both sides of the body are involved. 47, XXY. The male … X and Y chromosomes determine your sex. Background: Knowledge on the prevalence of sex chromosome abnormalities (SCAs) is limited, and delayed diagnosis or non-diagnosis of SCAs are a continuous concern. This treatment prevents osteoporosis and reduces cardiovascular risks of Turner syndrome. Turner syndrome is defined by the presence of a single X chromosome (sex chromosome disease, and not an autosomal disease like Down syndrome), complete or partial monosomy which is present in all cells or only in a certain proportion and associates phenotypic aspects such as nanism, defects in development of ovaries and various visceral malformations. Establishment of early therapy, allows the state of pregnancy through in vitro fertilization and birth. Turner syndrome presents a clinical picture, in which the existence of certain abnormalities is leading to the recognition and diagnosis of the syndrome at birth. Occasionally, in females with mild signs and symptoms of Turner syndrome, the diagnosis is delayed until the teen or young adult years. complications / diagnosis / embryology / epidemiology / etiology / metabolism / microbiology / surgery / therapy, PROTEIN TYROSINE PHOSPHATASE, NON-RECEPTOR TYPE 11, MeSH 2010 © U.S. National Library of Medicine®, More information from the Genetics Home Reference Website, Noonan syndrome - Genetics Home Reference, Orphanet Journal of Rare Diseases | Full text | Noonan syndrome, Statins 'reverse' Noonan syndrome learning disabilities - Medical News Today, Noonan syndrome: MedlinePlus Medical Encyclopedia, Forgotten Diseases Research Foundation | Global Growth Curves, Noonan Syndrome Angels: An Italian patient organisation is fighting for them, rare-diseases — National Organization for Rare Disorders, The Noonan Syndrome Support Group Website, Cardiovascular Genetics at Children's Hospital Boston, Consult HON's world-wide database of medical meetings. It is characterized clinically by short stature, gonadal dysgenesis, sexual infantilism, and various somatic anomalies. Mutations in a several genes (PTPN11, KRAS, SOS1, NF1 and RAF1) have been associated the the NS phenotype. In conclusion, the majority of the sSMCs in patients with a mos 45,X/46,X,+mar karyotype were derived from the sex chro-mosomes. Unaffected Female (pedigree symbol) Noonan syndrome presents phenotypically as a male Turner syndrome (45,X). Other cell lines may contain two X chromosomes, three X chromosomes, very rarely XY chromosomes, or may contain structural abnormalities of chromosome X or Y. A karyotype is the test that is used to look at the chromosomes and determine if someone has Turner Syndrome or another chromosomal disorder such as Down Syndrome. 47, XY, Trisomy 21. A TS diagnosis only applies to phenotypical females (those born with female sexual organs internally and externally). Male karyotypes are used to identify chromosomal defects in males. Patau syndrome (Trisomy 13), caused by an extra chromosome 13. Such cases have an increased risk to develop gonadoblastoma and require a removal of gonadal rudiments. TURNER'S SYNDROME in its most common form is a congenital disorder appearing in phenotypic females. Molecular biology tests, because in 5% – 10% of cases of Turner syndrome there is an XY cell clone that can not be detected by classical cytogenetics. Prenatal diagnosis in Turner syndrome is on the specific ultrasound signs, such as the vizualization of cystic higroma in first or second pregnancy trimester, fetal edema and highlighting the small size of the fetus. Turner stigmata have not previously been reported in DMPH. Klinefelter syndrome (XXY) and XYY syndrome are examples of sex abnormalities found in male karyotypes while Turner syndrome (X0) and triple X syndrome are the examples of sex abnormalities found in female karyotypes. It is also noted low implantation of hair, cardiovascular abnormalities of which coarctation of the aorta is the common. Infertile , streak ovaries (No males) Email This BlogThis! Besides the numerical abnormalities in Turner syndrome are structural abnormalities of one of the two X chromosomes, homogeneous or mosaic, all fitting as Turner syndrome cytogenetic varieties. A TS diagnosis only applies to phenotypical females (those born with female sexual organs internally and externally). Signs and symptoms vary among those affected. Structural abnormalities of the X chromosome, occurring in 30% of cases of Turner syndrome are often of paternal origin and in this situation, paternal age can be considered a risk factor. Chromosomes are numbered from 1 through 22; the 23rd pair normally consists of one X and one Y chromosome for males and two X chromosomes for females. Turner syndrome, characterized by the presence of a monosomy X cell line, is a common chromosomal disorder. The phenotype bears similarities to that of TURNER SYNDROMEthat occurs only in females and has its basis in a 45, X karyotype abnormality. Although Turner syndrome is most commonly associated with a 45,X genotype, other mosaic genotypes are present in approximately half of all cases. Turner syndrome, caused by missing one X chromosome in females. Women with Turner Syndrome typically have short stature, webbing of the posterior neck, an increased “carrying angle” at the elbows (cubitus valgus), and delayed or absent puberty (Turner 1938). The aim of this first analysis from Turner Syndrome Life Course Project was to identify the relationship between karyotype and clinical outcomes of adult women with TS. Turner syndrome may be diagnosed before birth (prenatally), during infancy or in early childhood. The cause is a missing or incomplete X chromosome (the chromosome that determines a person’s sex before birth). 47, XX, Trisomy 21. Turner syndrome (TS) is a rare genetic condition in which a girl or woman doesn’t have the usual pair of 2 X chromosomes. People typically have two sex chromosomes in each cell: females have two X chromosomes, while males have one X chromosome and one Y chromosome . The classic cause of the disease is the complete absence of a second sex chromosome, leading to an abnormal 45,X karyotype, as opposed to the normal 46,XX or 46,XY karyotyp… Down Syndrome Male Karyotype. The male karyotype testing is done to identify the chromosomal aberrations present in males which is characterized by the 23 rd chromosome pair consisting of an X and a Y chromosome and the female karyotypes reveal information on chromosomal aberrations of females which is characterized by the 23 rd chromosome pair having two X chromosomes in it. Turner Syndrome. In the past, it was also referred to, incorrectly, as ‘Male Turner Syndrome, ‘Female Pseudo-Turner Syndrome’ and ‘Turner Phenotype with Normal Karyotype’. The molecular cytogenetic features of sSMCs may provide useful information for genetic counseling, prenatal We present an unusual African-American family with two SLE-affected individuals in which one of the patients with SLE also has Turner's syndrome (46,X,del(X)(q13)). - Turner Syndrome, Subheadings: A TS diagnosis only applies to phenotypical females (those born with female sexual organs internally and externally). What is Turner syndrome? The underlying genetic mutations affect the number and function of sex chromosomes (e.g., in Turner syndrome), lead to structural changes with altered sensitivity of hormone receptors (e.g., androgen insensitivity syndrome), or alter the function of enzymes responsible for sex hormone synthesis (e.g., congenital adrenal hyperplasia). Typically, these men have dysmorphic features such as webbed neck, short stature, low-set ears and wide-set eyes. Patients with Turner syndrome are usually phenotypically female, and male cases are rarely reported. Here, we report a fetus with a mosaic karyotype: mos 45,X/46,X,del(Y)(q11.21).
