 What are the symptoms of Turner syndrome ? 
 What are the signs and symptoms of Turner syndrome? There are various signs and symptoms of Turner syndrome, which can range from very mild to more severe. Short stature is the most common feature and usually becomes apparent by age 5. In early childhood, frequent middle ear infections are common and can lead to hearing loss in some cases. Most affected girls do not produce the necessary sex hormones for puberty, so they don't have a pubertal growth spurt, start their periods or develop breasts without hormone treatment. While most affected women are infertile, pregnancy is possible with egg donation and assisted reproductive technology. Intelligence is usually normal, but developmental delay, learning disabilities, and/or behavioral problems are sometimes present. Additional symptoms of Turner syndrome may include: a wide, webbed neck a low or indistinct hairline in the back of the head swelling (lymphedema) of the hands and feet broad chest and widely spaced nipples arms that turn out slightly at the elbow congenital heart defects or heart murmur scoliosis (curving of the spine) or other skeletal abnormalities kidney problems an underactive thyroid gland a slightly increased risk to develop diabetes, especially if older or overweight osteoporosis due to a lack of estrogen, (usually prevented by hormone replacement therapy). The Human Phenotype Ontology provides the following list of signs and symptoms for Turner syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms.

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
