Turner’s syndrome and other birth defects are covered here in Dr. Leone’s Knowledge Center.
In 1 of every 3,000 live births, a single X chromosome (XO) is present instead of the normal XX or XY combination, resulting in Turner’s syndrome. Patients are phenotypically females with short stature, a webbed neck, and a low hairline. Girls with Turner’s syndrome do not pass through puberty or develop secondary sexual characteristics because of the lack of sex steroid hormones. Cubitus varus is a common finding in Turner’s syndrome but rarely requires treatment. Scoliosis may also develop and management is similar to that for idiopathic curves.¹
