Trisomy X
Trisomy x syndrome, also known as triple x and 47xxx, is characterized by the presence of an extra x chromosome in each cell of a female. Three x chromosomes are present, rather than a normal pair in the nuclei of body cells. The first published report of a women with triple x syndrome was Patricia A. Jacobs at Western General Hospital in Edinburg, Scotland, in 1959.
The condition occurs in about 1 in 1,000 newborn girls. Five to 10 girls with triple x syndrome are born in the united states each day. Some of the symptoms are they are taller than average height with especially long legs, delayed development of speech and language skills as well as motor skills such as sitting up and walking, and they have some learning disabilities, such as difficulty with reading, understanding or math. Triple x syndrome is genetic and usually not inherited, it's due to an error in cell division. The error can happen before conception or early in embryo's development, resulting in one of these forms of triple x syndrome.

They also have behavior problems, poor self-esteem, and need for additional assistance with learning, activities of daily living, school or work. Trisomy x may be suspected based upon the identification of characteristics developmental, behavioral or learning disabilities. A diagnosis can be confirmed by a clinical evaluation, a detailed family history, and certain specialized test such as chromosomal analysis performed on blood samples that can reveal the presence of an extra X chromosome in body cells. Trisomy x is increasingly being diagnosed before birth based on chromosomal analysis performed subsequent to amniocentesis or chorionic villus
