What is Turner's syndrome?

Turner's syndrome is a genetic disease or condition in which the individual has only one X chromosome, instead of two X (female) or one X and one Y. The syndrome was named after H.H. Turner, who first described it. About 1 child in 2,500 (live births) has this syndrome. Most embryos that start this way do not survive to birth. These individuals show the physical features of females, although secondary sex features (breasts, pubic hair) are poorly developed, and they cannot bear children (ovaries fail to develop). More information can be found in a medical genetics textbook.
