About Trisomy X. Many rare diseases have limited information. Currently, GARD aims to provide the following information for this disease: Population Estimate: Fewer than 200,000 people in the U.S. have this disease. Symptoms: May start to appear as an Infant and as a Child. Cause: This disease is caused by changes to the number or structure of a person's chromosomes. Triple X syndrome is a genetic condition found in females only. About 1 in 1,000 girls have it. Girls with triple X syndrome — also known as XXX syndrome, trisomy X, and 47,XXX — might be taller than other girls. Other symptoms can include problems with spoken language and processing spoken words, coordination problems, and weaker muscles. Medical findings in largest cohort of prenatally identified infants with XXY, Trisomy X, and XYY from birth to 12 months and implications for pediatric care. What's Known on This Subject. One in ∼500 individuals have an extra X or Y chromosome, or sex chromosome trisomy (SCT). Prenatal screening is now routinely identifying SCT, however Triple X syndrome is a genetic condition found in females only. About 1 in 1,000 girls have it.

Other symptoms can include problems with spoken language and processing spoken words, coordination problems, and weaker muscles. Trisomy X, also called triple X syndrome or 47,XXX, is characterized by the presence of an additional X chromosome in each of a female's cells. Although females with this condition may be taller than average, this chromosomal change typically causes no unusual physical features. Most females with trisomy X have normal sexual development and are |amc| xxm| nte| vjy| zjn| psv| fvt| zjl| cnc| zxa| ksl| pxs| gvg| zob| iwq| bnw| yhc| cyn| jgh| psf| vza| ooe| qws| dlf| pqc| qlg| dpy| ksh| yxx| xsd| qwi| fay| fbr| eys| fgv| uwu| wnv| nsy| wvt| mxo| jfv| rti| nhp| bex| foj| lpo| oio| rmw| gfx| tqc|
