This condition cannot affect males, since they must have a Y chromosome to be male. A condition of YO is automatically lethal since the X chromosome carries the genetic information vital to living. The name comes from the first person to describe and acknowledge the conditons, H.H. Turner, who did so in 1938. The first person to describe it on a genetic basis was a Dr. Ford in 1959. There is a distinctive phenotype for people with Turner's Syndrome which is a short stature with under-developed sexual characteristics.
Symptoms begin to show at the newborn stage as being underweight and having puffy hands and feet.
Later on in development, features such as downslanting eyes, high palate, and small lower jaw may become apparent. The cardiovascular system can be weakened and the aorta has a constricted area in the arch. There are also obvious problems with fertility since gametes are formed to be haploid of the normal chromosome number. Occasionally, however, there is a case to where a normal gamete can form and fertilization can occur. Typically, Turner's Syndrome subjects can reproduce if fertilization is done in vitro.
