similarities between down syndrome and klinefelter syndromesimilarities between down syndrome and klinefelter syndrome

If the sperm holds a Y chromosome when it meets the egg, the resulting baby will be a male (46, XY). While both syndromes can present with similar physical characteristics, such as low muscle tone, facial differences and varying degrees of intellectual disability, the underlying genetic cause of each syndrome is what makes them unique. Children and adults may be taller than average, with proportionally longer arms and legs, and they may have less-muscular bodies, more belly fat, wider hips, narrower shoulders, or minor to moderate learning disabilities. Turner syndrome is best managed when a diagnosis is made as early as possible, though many girls are not diagnosed until later childhood or early adolescence. Other features often found include small jaw with carp-like mouth, epicanthic folds or ptosis, and multiple lentigenes. Autoimmune diseases can be broadly divided into those affecting mainly one organ, such as thyroid disease and type 1 diabetes, and those affecting multiple organs, such as SLE and rheumatoid, Autoimmune thyroid disease is the commonest autoimmune condition recognized in Turner's syndrome. This karyotype shows all of the chromosomes from a person with the 47, XXY chromosomal arrangement. WebKlinefelter's syndrome (KS) affects one in 600 men and Turner's syndrome (TS), one in 2500 women. Usually, symptoms are subtle and subjects do not realize they are affected.

This can cause physical and mental delays, along with other symptoms like low muscle tone and distinct physical features, such as low-set ears, an upward slant to the eyes, and a flattened facial profile. The study found substantial differences in framings of information, and social support available online for Klinefelter syndrome and Down syndrome. This syndrome is also associated with behavioural problems, learning difficulties, congenital heart defects, bone abnormalities, tremor, obesity, type 2 diabetes and/orrespiratory problems. Klinefelter's syndrome co-exists in 0.25% as a result of double non-disjunction. Common reasons for first surgery failures include incomplete resection of seizure focus, incorrect identification of seizure focus and recurrence of tumor. This chromosome is large compared with the male conferring Y sex chromosome. These including respiratory infections, problems with the gastrointestinal (digestive) tract, leukemia (a blood cancer), eye problems, hearing loss, and hypothyroidism. Would you like to know more about What is the difference between transgenesis and selective breeding,which describes the two methods in detail. Copyright 2008 Published by Elsevier Ltd. It affects only females. Both syndrome's indicate the presence of a 47th chromosome (or Turner's syndrome and Klinefelter's syndrome involve abnormalities in the X sex chromosome. pathology seminar mbbs student. In most cases, the differences in their puberty and/or fertility are because the testicles have early failure and cannot make enough testosterone and/or sperm. They have some level of intellectual disability, which is usually mild to moderate. The risk is higher in those over 35 years old who become pregnant, but the majority of babies born with trisomy are to parents younger than 35 years of age because there are statistically more births in those under 35 years. Gonadal dysfunction and beyond: Clinical challenges in children, adolescents, and adults with 47,XXY KlinefeltersyndromeAm J Med Genet C Semin Med Genet. WebKlinefelter syndrome (KS), also known as 47,XXY, is an aneuploid genetic condition where a male has an additional copy of the X chromosome. TRISOMY 21- DOWN SYNDROME Immediate peri-partum hysterectomy was performed in one patient. The Glickman Urological & Kidney Institute offers innovative treatments in urology and kidney medicine, including minimally invasive, scarless options for urologic procedures and medical management of kidney disease. Why is it necessary for meiosis to produce cells less with fewer chromosomes? Down syndrome is really the only trisomy compatible with life. Since there was a known link between gonadal dysgenesis and thyroid autoimmunity, it was suspected that there was a common cause for the chromosomal abnormalities. WebIn both Turner syndrome (TS) and Klinefelter syndrome (KS) copy number aberrations of the X chromosome lead to various developmental symptoms. We do not endorse non-Cleveland Clinic products or services. Down syndrome and Klinefelter syndrome are two types of trisomy conditions. What prenatal screenings do you recommend to verify if my baby has a genetic condition? Patients have an essentially normal life expectancy but require regular medical follow-up. Turner syndrome affects only females and involves a missing or altered X chromosome in all or some cells. Down's syndrome is caused by trisomy of chromosome 21one of the smallest chromosomes. A total of seventeen patients (involving 10 females) were included in the study. Salt Lake City (UT): Genetic Science Learning Center; 2014 RSV replication and interleukin 6 (IL-6) levels in RSV-infected HEp-2 cells were compared before and after FIP-fve treatment. WebDifferentiate between : Klinefelters syndrome and Downs syndrome Medium Solution Verified by Toppr In both Klinefelters and Downs syndromes, there are 47 chromosomes Some will develop the varied and often subtle features of Klinefelter syndrome. WebPeople who have Down syndrome may look similar and have similar qualities, but the conditions manifest differently for each person. Activate your 30 day free trialto continue reading. Normally, each pair would contain two chromosomes, but a third chromosome forms and attaches to the pair, creating a trisomy, which literally translates to three bodies.. The detailed analysis of genetic mechanisms is dealt with below. Klinefelter syndrome happens when there is an extra X chromosome in the genetic code. Intravitreal thalidomide may be a potential alternative to treat intraocular inflammation in corticosteroid-sparing therapies. Genetics home reference: https://ghr.nlm.nih.gov/primer/mutationsanddisorders/structuralchanges, To learn more about translocations, visit the, Genetic Science Learning Center. (This can include being too tall, having long legs and a short trunk and the shoulders being equal to hips in size rather than wider, which is more typical in a male.). Digital marketing. 51-61, Clinical Radiology, Volume 69, Issue 8, 2014, pp. Most males have an X chromosome and a Y chromosome (46, XY), and most females have two X chromosomes (46, XX). While both are caused by an extra chromosome, the two conditions differ in the type of extra chromosome present. Read More What Is The Difference Between Antistatic And EsdContinue. The dominant associations are with thyroid disease, diabetes, and celiac disease but the spectrum is wide (Soderbergh et al., 2006). The three copies of chromosome 21 are circled. Children with Klinefelter syndrome may also need changes in the classroom to help them learn. Children with Down syndrome usually develop more slowly than their peers. How do you telepathically connet with the astral plain? The SlideShare family just got bigger. WebPeople with Klinefelter syndrome are also more likely to develop certain conditions that are part what is known as metabolic syndrome. The survival rate for babies born with trisomy 18 or trisomy 13 is low after the first few weeks of life (neonatal period) due to the severity of the condition, especially delayed or abnormal organ development. Autoimmune diseases (including type 1 diabetes. Since there is no way to prevent genetic abnormalities like trisomy conditions, if you plan on becoming pregnant, talk with your healthcare provider about genetic testing to assess your risk of having a child with a genetic condition. Each cell contains half the amount of DNA as the original, so the copy contains 23 chromosomes from the original 46. Having testicular failure (not making enough. Clipping is a handy way to collect important slides you want to go back to later. Monosomy occurs when you are missing a copy of a chromosome. Treatment for children born with trisomy includes: You cant prevent genetic conditions like trisomy from occurring because the chromosome error occurs randomly during cell division. AND How can a map enhance your understanding? This chromosome is large compared with the male conferring Y sex chromosome. This is followed by an account of the disturbances of chromosomal number and structure, and the underlying mechanisms leading to the various karyotypes are outlined. The experimental protocol consisted of two subcutaneous injections of BCG, followed by two intravitreal injections of the same antigen, inducing panuveitis. Major and minor histocompatibility antigens are important for organ and tissue transplants, as they are responsible for determining donor and recipient compatibility. FIP-fve inhibited viral titers on plaque assay and Western blot, as well as inhibited RSV-stimulated expression of IL-6 on ELISA and RT-PCR. The typical features of Turner's syndrome include short stature, infertility, and hypogonadism. Policy. Disclosures Often, they do not know that they have an extra chromosome. "Examples of Aneuploidy." FIP-fve is a widely used, natural compound from F. velutipes that may be a safe agent for viral prevention and even therapy. Policy. Of the ten patients who were Engel Class I, seven required extension of the previous resection margins, while three had surgery for recurrence of previously partially resected tumor.

It happens randomly and the diagnosis is not a result of something the parent did during pregnancy. They have some level of intellectual disability, which is usually mild to moderate. In people with very mild cases of Klinefelter syndrome those without symptoms the condition may never be diagnosed or treated. About 30 percent of girls with the disorder are missing the X chromosome in just some of their cells. The evidence for the nature, prevalence, and clinical consequences of autoimmune disorders in Turner's syndrome, Klinefelter's syndrome, and Down's syndrome is then reviewed, emphasising the similarities and differences between them.

Down's syndrome IS an example of trisomy. 1 Learn more about these other conditions in the What conditions or disorders are commonly associated with Down The XXY chromosome arrangement affects primarily sexual development. Klinefelter syndrome is fairly common, happening in about 1 in 600 males, but many men (some say 70 to 80%) likely do not know they have this condition. When your body has an extra copy of a chromosome (trisomy), your body has 47 total chromosomes. Following a screening, additional tests help confirm the diagnosis including: Trisomy is a lifelong condition and requires long-term treatment to alleviate any symptoms associated with the condition. Physical features may appear around the time of puberty, when gender identity and sexual characteristics begin to form. Probably because of the need to balance the amount of genetic material in the two sexes, in men with the normal 46,XY karyotype both of the sex chromosomes are fully activated; in females with the normal 46,XX, karyotype only one chromosome is fully active, where as the other is largely inactivea process eponymously termed Lyonization (Lyon, 1961).
