General Discussion

Turner syndrome is a rare chromosomal disorder of females characterized by short stature and the lack of sexual development at puberty. Other physical features may include a short neck with a webbed appearance, heart defects, kidney abnormalities, and/or various other malformations. Among affected females, there is also a heightened incidence of osteoporosis, type II diabetes, and hypothyroidism. There appears to be great variability in the degree to which girls with Turner syndrome are affected by any of its manifestations.

Turner syndrome occurs when one of the two X chromosomes normally found in women is missing or incomplete. Although the exact cause of Turner syndrome is not known, it appears to occur as a result of a random error during the division (meiosis) of sex cells.
