TURNER SYNDROME
DESCRIPTION |
|
|
Chromosomes are structures in the
nucleus of every cell in the body. Chromosomes contain the genetic
information necessary to direct the growth and functioning of all
the cells and systems of the body. A normal person has a total of 46
chromosomes in each cell, two of which are responsible for
determining the sex of that person. Normally, females have two X
chromosomes and males have one X and one Y chromosome.
In Turner syndrome, an error very early in development results in an
abnormal number and arrangement of chromosomes. Most commonly, a
patient with Turner syndrome will be born with 45 chromosomes in
each cell rather than 46. The missing chromosome is an X chromosome.
About 1 in every 8,000 babies born has Turner syndrome. |
