A Barr body is the inactivated X chromosome that is usually found in the nuclei of female somatic cells. It can also occur in males when there is an abnormality and the male is XXY instead of the normal XY, a condition known as Klinefelter's syndrome.
Only a small fraction of the inactive X-chromosome, including the genes located in the pseudoautosomal region at Xp22.3, escapes the global silencing process (2). The inactive chromosome remains in the nucleus and can be detected cytologically as a Barr body in somatic cells (3). The Barr body is found only in cells containing more than one X-chromosome, if cells are trisomic for the X-chromosome, two Barr bodies will be detected. The staining procedures used to detect Barr bodies argue for a global difference in chromatin condensation (4).
