Turner Syndrome

Turner syndrome occurs in girls and is characterized by abnormal external appearance (such as webbed neck and cubitus valgus), abnormalities of certain internal organs (particularly heart and kidneys), dysgenesis of the ovaries, and short stature. It is caused by the complete or partial absence of one of the two X chromosomes. There is no increased prevalence of mental retardation, however difficulties with visuospatial tasks and vulnerability to specific behavioral problems, as well as learning disabilities are often seen. Individuals are susceptible to a number of medical problems for which monitoring throughout adult life is recommended.
