Turner syndrome is a disorder caused by a partially or completely missing X chromosome. This condition affects only females.
Most people have 46 chromosomes in each cell-23 from their mother and 23 from their father. The 46 chromosomes are coupled into 23 pairs. The 23rd pair of chromosomes are called the sex chromosomes -X and Y- because they determine whether a person is male or female. Females have two X chromosomes (XX) in most of their cells, and males have one X chromosome and one Y chromosome (XY) in most of their cells.
Turner syndrome most often occurs when a female has one normal X chromosome (45th), but the other X chromosome (46th) is missing - 45X. Other forms of Turner syndrome result when one of the two chromosomes is partially missing or structurally abnormal or there is Y material present. (Mosaic)
This disorder occurs in about 1 in every 2,000-4,000 live births worldwide and they are the 1% who survive.
It affects all races and regions of the world equally. Generally, Turner syndrome is not passed on from mother to child.
Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects. In most cases, girls/women with Turner syndrome are infertile.
Turner syndrome may be diagnosed before birth (prenatally), during infancy or in early childhood. Occasionally, in females with mild signs and symptoms of Turner syndrome, the diagnosis is delayed until the teen years - when puberty is delayed.
Girls and women with Turner syndrome need ongoing medical care from a variety of specialists. Regular checkups and appropriate care can help most girls and women lead healthy, independent lives. -
